Rudy8, I see your from Kalamazoo did you go to Western Mich U? I did some grad work there on the supercharger. My son got his BSME from there also.
Funny both of the Professors who helped me were long time tenured profs there but now have great private sector jobs. Most notably Dr. Jay Easwaren. Now has a company that overhauls APU's. Dr. Curt Swanson is in London doing something i don't know.

HELP!!!

While coercing the wire loom for the ECU, one of the white wires (the one that goes to one of the two boxes) popped out. I suspect it was tucked in behind one of the black shrink wraps, and it doesn't look like it was a very good solder joint to begin with.

Could some kind soul please take a nice photo of the loom where that white wire goes in?

Thanks in advance............


I'll be able to take a picture of it tonight after work.

Thank you, Adrian. I found the connection and have repaired it...:)

YES richard...i got my bachelors from there in 83 but am originally from detroit area. i dont know the profs you mentioned, buy i will tell you that kalamazoo and wmu have truly transformed into a dynamic and growing place...not like it was when i was a student. you wouldnt recognize the place.
what kind of program on superchargers did you participate in...engineering i presume?

good to hear from you,

In the engineering school worked with Fluid Dynamics and Materials. All for the supercharger. My son helped Pro Swanson build a spin fixture and I donated a supercharger to use on it.

My son graduated in '91. He studied materials with Easwaren too. He now works for Boeing.

Great school and a bargin to boot. Underated except in aviation. I have not visited in many years and have only seen pictures of the new airport campus at Battle Creek. Donated by Kellogs was it? That must be awsome.

Oh yeh, Kalamazoo has a great WWll aero museum. Nice restoration work on some of those. When I visited it was like $3.00 entrey fee. It's on the commercial airport.

You know there are poeople who don't think there really is a Kalamazoo.
I was on a flight to Detroit then Kalamazoo and when the woman next to me asked where I was going she thought I was joking.



There you go Jon, 101 and counting. So who is the longwinded jerk helping you?
From now on I only speak on my thread.

sorry for discussing personal stuff everyone on this turbo thread...last irrelevant post...

richard, just took my daughter to the newly opened AIRZOO today...pretty cool. they have an sr71, and lots of other stuff including flight simulators that move in 6 dimiensions or more.
they kept the old one open you talked about...it has more stuff...engines, plane parts and tons of planes...still better than the new air zoo by far. my 3 yr old likes the new one because they have indoor amusement rides and popcorn for her.!

ps. if i drive my turboed car out there, would you help a fellow alumni and tweak it for me?
ha ha ?(go broncos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:)

My thread, my thread, this is the enemys turf.

I didn't know they opened a new one. Hell I'd never miss a chance to just stand by an SR 71. You can feel the power even when are not running.

Do you really think a turbo'ed Rx8 can make it that far?? Or were you going to truck it??

My thread, my thread, this is the enemys turf.
Uh oh! Look out Jon, RP is trying to Bogart your thread! :p

well, if jon is the guinea pig for one of the first turbos with 101 pages (go jon!), than i can log the first cross country trip and engine rebuild combo!
ill let you know if it makes it to the end of my driveway. if so, ill just head west and see what happens...have your laptop and a wrench ready! (you can put one of your newfangled superchargers on!)

WHOA BABY!! :D :D :D :D :D

I finally got that pesky oil pressure switch out. I found a semi-deep 24mm socket that fit in the confines. Finished up the details, fired her up, checked for leaks and took her for a spin around the outskirts of the neighborhood. Sheesh...even in Denver, where the air is rare, this thing starts cranking in the mid-2K range and just keeps on cranking! I have a blowoff on the way, and these things NEED ONE. When you let off the throttle, you can definitely hear the excess boost whimpering around trying to find a way out.

Only thing left to do is find a good place to hang the eManage unit behind the glove box. Mine is too full to hold it and all the other stuff that lives in there.

congrats!
cant wait to join in on the fun
how deep was the 24 mm socket?

The one I found was about 1/2 way between a short and normal deep socket...say 3 1/2 inches or so. I'm guessing here...:)

well i just got my support tool and i never used these before. This is very new to me and i need some help. I have the turbo kit installed already, the E-manage has the map that it brings. I have a labtop what do i need to do to put on mazdamaniac map that he creaded. This is the first time so please step by step. THANK YOU

Cool. I might have to wash mine despite the sub-freezing temps and windchill.:p

I'm throwing the laptop and cables in the car right now.

I have played with some versions of the map I installed in your car - it is very rich in some spots which probably don't need to be.

I have also spent some time with the Greddy map. Most of the issues seem to be the transition into boost and the 4800 RPM range, regardless of boost. I made those areas wetter and started pulling some ignition timing under boost - something that everyone should consider. You will need to get that ignition harness installed for that.
When are you going to put the E-01 in?

Any of you with the turbo kit care to get rid of your old stock exhaust manifold?

Any of you with the turbo kit care to get rid of your old stock exhaust manifold?

CRH
Please tell me you don't want to start your header project based off of that thing! The exhaust holes aren't even close to lining up with the engine's ports. I am almost ready to go to the machine shop with the new CAD drawings of the exhaust flange I am making. I have the exact shape and size worked out. If you want a flange, let me know. The first ones will just be 1/2" mild steel.

Okay, I won't tell you that. I would like a manifold to give to my machinist so we know the general space we have for design limits. Geez. :) I would love to have a sample of that flange you are using. Mild steel is fine for mock-ups. How can I re-pay you? Deep discount on a Ti PPF, perhaps?

Do you think the exhaust problems are largely caused by the port mis-match? Just wondering.

CRH

Charles I have my stock exhaust manifold lying around after my turbo install. If you want to take it shoot me a PM with your adderess. One of these days I will figure out what PPF means.

I think is it a combination of things. The stock manifold does indeed look like crap in terms of where the air flows through it. However, if the exhaust ports themselves don't really flow much better, the stock manifold suddenly isn't much of a problem. I think that the ports need to be cleaned up, they need to be totally separated, and we need a better exhaust manifold. For all I know this may still only yield a few horsepower since we have no port overlap to aid in scavenging. I don't yet know.

Since I don't own an RX-8, a ppf won't do me much good.

One of these days I will figure out what PPF means.

Before i open i new thread i thought i post this picture here.....
found on a german form.....one of the german forummembers is working on a 460hp turbo and it will be finnished with in 3 months.
+sry for my bad english+

I had the turbo kit installed last week by Acosta Motorsports last week. They did a great job - the install was $1200, which I knew ahead of time. Some problems I have encountered;
- CEL at start up, multiple times after resetting
spoke to Benny at Greddy, he told me that 50% of the installs could see this CEL which Greddy was working on. I have a Greddy wide band A/F gauge. It seems like the tuning is too rich on start up, reading initially 11-12, as opposed to 14-15 stock, which was great.

- Car stumbling and running too rich at WOT - after 5k and WOT - A/F gauge is reading 11 and lower.
Spoke to Benny about this condition and he told me the kit was designed to be used with stock CAT, I have SR high flow cat. He told me to replace or retune. I plan on bringing car back to Acosta next week to retune.
Over all I am rellly enjoying the turbo, what a difference, I am anxious to see difference tuned properly.

Thanks. I wonder what the weight reduction will be ?

Thanks. I wonder what the weight reduction will be ?
What? You mean take it out?
That would suck...

What? You mean take it out?
That would suck...

No doubt... I can't imagine how damaging wheel hop would be without the PPF to brace everything. Now a Titanium PPF would be pretty sweet : )

No, I meant the weight difference from the standard unit to the (hopefully) new titanium unit.

Ooh. Titanium.

That is a point where I think Mazda might have dropped the ball. I guess it was just more economical to make the PPF out of stamped steel.
The Miata PPF is tubular steel.
The best construction is probably rolled CF, but there isn't any good way to do that via mass production.
The stock unit seems to weigh about 20 lbs. A CF version would probably be less than 10 lbs. Titanium would probably net out at 15 lbs or so, though titanium is overkill - it just doesn't have to be that strong.

Correct, Jeff, Ti is overkill and the raw stock price just jumped to $25/lb. I don't want to divert the subject away from GReddy or turbos but since we are here, this is the latest;

On Saturday Brian and I will get together and begin welding the very first PPF unit. We have decided to make it out of 6061-T4 aluminum because it is cheaper, lighter, and stronger than Ti, at least in this application. I originally selected Ti just to have some exotic metal on my car in the event I am selected for the USCC. Lately, though, I have noticed that those who were/are interested in my PPF were more captivated by weight loss than the Ti, itself(not to mention patient with how long this is taking). Between that and GeorgeH's suggestion that the Ti's modulus of elasticity might pose a problem, along with the recent price spike, we have switched to the 6061.(Thanks, G.)

The factory piece seems to weigh much more than 20 lbs. Either way, we will see a reduction of about 50-60%, overall, and the price will be very affordable for the serious enthusiast. We may offer the PPF with polished, anodized, and powder-painted finishes. I know the first one that goes on my car will be polished. I'll post photos as soon as I can on the PPF thread. Now, getting back to the Greddy topic.....

I have decided to quash the idea of putting a GReddy turbo on my car for several reasons that I won't get into here. However, since I only trust Mr. Abrams with the answer to this question I will offer him the second PPF in the finish of his choice if he chooses to help me. Knowing that I have been a real pain in the ass lately, my question is this;

Which specific GReddy parts do I need in order to most easily fine-tune my fuel and ignition systems? I plan on using the E-Manage, E-01, ignition harness, RPM adapter, and/or whatever else you tell me I will need. I plan on setting up the first map, assuming two are available, to provide the best all around N/A performance. The second map will be optimized to accomodate a 100-125 h.p. shot from my Zex kit. I already know which parameters I would like to use on the second map but I need to know if the E-Man can switch between the two using only the E-01(or do I need the Profec to do that?).

I realize this answer may be found elsewhere on this forum so if you can direct me to that thread the offer for the PPF still stands if you would be so kind as to help me with some of the details when I install this damn thing. Your knowledge and expertise are both priceless but the PPF is all I can offer. My daughter is too young.

Thanks, Jeff.

CRH

Mazda didn't make it out of titanium. Charles is making one out of titanium.
Obviously. :rolleyes:

The OEM piece looks like it is made out of scrap compared to the Miata PPF.

I'm down for an aluminum piece. Any way to get the weight savings, yet still keep the structural stiffness I'm all for.

As for the Greddy E Manage I am getting the software, ignition & injector harness to play with my E Manage.

Ooh. Free stuff! I'm such a parts-whore :D(but I don't have any real use for a child at the momenthttp://www.mazdamaniac.com/images/smiles/icon_shrug.gif):

First of all - I think the E-01 Profec is overkill for your application - unless you can still get the E-01 programmer only version. They have pulled it from production, so hurry up if you want one.
For real tuning purposes, a laptop is a better starting point since it has more screen real estate. If you don't have one, you can get one that is more than adequate for this purpose on E-Bay for $200.

I'm not sure you really want two separate sets of maps just to spray or not spray. It seems to me you should just tune as best you can with the E-Manage and let the Zex kit do what it likes best.
However, you could use the boost input on the E-Manage to control the fuel/timing and hook it up to the nitrous controller some how.

I think I'm just not understanding quite what you need.

Nitrous is quite different from boost in that you mix it with fuel like you would mix epoxy - in equal amounts. Just open the solenoids and stomp on it.
Now, if reducing your ignition timing or adding fuel without a dedicated fuel solenoid is what you are looking for, this is right up the E-Manage's alley.

Maybe if you can describe your goals for me in more detail and the issues as you see them, I could be of more help.

The E-Manage is a very capable tool (especially with the E-01 attached), but you might not need a Swiss Army knife to do the work of a spoon.

Since I have bagged the turbo idea, I agree that the Profec is overkill. The E-01 is still listed on-line. If I can't get that, I guess a laptop and the support tool are in order, eh? If I use a laptop, how do I switch maps as needed?

I thought about the boost input as you have because the Zex is triggered by throttle body voltage. I figured if I can tell the E-Man to cut the ignition timing when it sees 12v at one circuit AND 3.9v in another, I will have a fully-automated system. That would be awesome.

Remember, I am running a "wet" nitrous kit so I can jet it properly as a stand-alone application as opposed to needing the factory injectors to add fuel. That's why I would like two maps. In order to get to levels higher than the 55 shot I am currently using I need to reduce the ignition advance. I have been told there are limitations to the E-Man with regard to automating the timing reduction and nitrous hit in the manner I previously mentioned. If that is true, the closest I can come is a second map with the reduction in advance coming above 4K rpm. I am thinking that I can activate the second map when I am lurking around my favorite street racing area. Keeping my cruising rpm's below 4K will cause the engine to run as it would otherwise. In a racing situation I launch at 4k anyway so arming the nitrous with the second map activated will be as close as I can get to a fully automated stand-alone ECU. The nitrous shot hits at WOT.

Which finish would you like on that PPF?

CRH

OK. I get it now.

You don't need two maps.

If there is a trigger or control voltage of any kind present from the Zex kit when it starts to spray, you just wire it up with a transistor or similar to produce a voltage between 2v and 5v DC (unless it is already in that range, in which case you can hook it up directly).
You then wire that to the boost input on the E-Manage.
Then you set up the ignition map to retard however much you want when it sees the amount of "boost" to which the above mentioned voltage is equivalent (ie - 2.05v is 9 PSI to the E-Manage).
That way, it will never retard the ignition under normal driving situations so you don't have to "lurk".

Better yet, if you are using a "progressive" nitrous kit, you can have the ignition follow the duty cycle of the solenoid.
That might be more difficult if the solenoid is pulsed, but it can be done.

Even more trick, you can still have ignition control when driving under "normal" conditions if you want (though I found only minimal benefit from ignition advance when N/A).
If you set the ignition map to control via the AFM, it expects to see a voltage from 1.2v or so up to about 4.3v.
You set your map to run from 1.1v to 5v. Then, you use the transistor setup from above to produce exactly 5v when the nitrous is on.
You splice that voltage to the MAF circuit via a diode to the E-Manage (which will keep the PCM happy - you don't want 5v suddenly telling the PCM that you are going supersonic) so that when the NO2 is flowing, the map goes to full.
Then, you can tune that last timing row (that the car would never make it to on its own normal air flow) for the amount of retard you need while spraying.

BTW - I can build the ignition protection circuit for you, when you need it. I have all the parts in the shop.

The factory piece seems to weigh much more than 20 lbs. Either way, we will see a reduction of about 50-60%, overall, and the price will be very affordable for the serious enthusiast. We may offer the PPF with polished, anodized, and powder-painted finishes. I know the first one that goes on my car will be polished. I'll post photos as soon as I can on the PPF thread.

Although I haven't seen the PPF thread yet (too busy lately, my job is killing me) the whole project sound great Charles. I am in the weight saving bussiness too, like Fanman said, so I might be very interested. My titanium exhaust will match perfectly with a titanium PPF :rolleyes: Oh, well, I forgot, if you plan on shipping on international scale...
maybe we can chat privately about this one...

I would take an aluminum one. It is much less expensive & is easier to weld. Titanium you need a complete argon environment. You can make aluminum very strong just adjust the thickness. This car can really use these weight savings, it's not like we have a 3600 lb. car that you drop 20 lbs. & it makes no difference. At 3000 lbs. you take 50-100 lbs. off this car & it will besubstantial.

I have a question....Im buying the Greddy turbo for my 8 in about 3 months, does it come with a blow-off valve or do you have to order that seperate? and...is it worth installing yourself, or are you better off getting a professional to do it for you?

http://www.mazdamaniac.com/images/misc/searchdumbass.jpg

Customized search flame pictures! Now you're really raising the bar... :D

jds

http://www.mazdamaniac.com/images/misc/searchdumbass.jpg

No it does not come with a BOV, you have to do some welding if you want one. Best bet is the Greddy Type S/Type RS or the HKS SSV.

Unless you are a pro I would not advise that you install this yourself. Unless you have a lift, it is not an easy install as the turbo has to go behind the right wheel well.

Jeff, it might be more efficient to move our conversation to the p.m. or telephone so as to not clutter up this thread. If that doesn't suit you then I'll continue right as we are. Thanks for that offer on the coil circuit. It would be a huge help. BTW, I ordered my E-Man, E-01, ignition harness, and rpm extractor. The E-01 and extractor are not due 'til end of March.

Anyway, I gotta run for the moment. Is there any way we can communicate directly so as to speed up the communication process? Is it possible for me to install this stuff and drive to wherever you are and spend a weekend together tuning the map(s), installing your new PPF, and riding around in a 400+ rwhp RX-8?

Your interpretation of that which I am trying to do is exactly on target. I ran that very same idea past my local GReddy "tuner" and he said the E-Man would not work that way. Of course, he was also among those who said nitrous wouldn't work either. Let's prove these so called "professional' tuners wrong once again. Remember, Acosta early on told another forum member that 300+ h.p. would "break your engine" and laughed at the very notion. I am finding out that the so called "experts" know nothing more than the rest of us. The difference is that we are sharing our results.

Which finish is it that you would like for your PPF?

Thanks, again for the help. You are a Godsend.

Charles Hill

The problem with most "expert anything" is that they tend to not think outside of the box. They often learned it one way...and despite the fact that there are other ways to do things...they say that their way is the "only way that works"

Real innovators...usually don't profess to be experts at anything...they are always students.
The best way is what works now...till a better solution comes along.

The last part is really important though...the new solution has to work better............

Change for changes sake...= Marketing:D...and someone selling you a line!

Keep it on a thread someplace here....there is always someone who will get information out of it..............(like me :D)

Swedishmax did exactly what he was supposed to do, search. That's how he ended up here. The problem is that I have somewhat hijacked this thread and now we are talking about Ti/aluminum PPF's and ways to make the E-Man work with my nitrous set up so as to reach higher boost levels while keeping it simple. That's my fault. (Although at 104 pages I might say that we have said all that there is for the time being about the GReddy turbo which is why y'all followed me on the hijack.) Anyway.....

The Zex Smart System is activated via throttle body voltage from a "T" splice that connects the Zex's processor card to the factory throttle wire circuit. Since the Zex system is completely modular the only way to access the voltage which actually snap the solenoids open would be to crack open the module, which I am not prone to do. Therefore, the way to make the E-Manage and Zex work together would be use a DPST switch on the arming side of the nitrous system. One circuit would carry the 12v needed to "arm" the system and the other would carry the signal that tells the E-Man that the nitrous is actually spraying. In other words, the boost circuit would see the target voltage ONLY when the nitrous system is actually ready for use. To omit this switch in this particular use would cause the E-Man to think that everytime WOT was present the nitrous would also be present. How's that for a solution? Here's how the Zex/E-Man system would work;

We set up the optimum map for N/A applications. Whatever A/F ratios work best, ignition timing, etc. The car gets that additional 20-30 h.p. we all hear is missing from the factory. WOT situations would not encounter the ignition retard because the boost circuit is not in-line. Then, when we "arm" the nitrous with the dash switch two things happen. First, the 12v needed to power up the nitrous system is activated (pole 1) and the ignition retard map that kicks in under boost via a voltage trigger to the boost circuit is also made available(pole 2). When we go WOT with the nitrous system armed the E-Man properly assumes that the nitrous is spraying because the trigger voltage tells it that is the case.

This is exactly how I have wanted the E-Man to work with my nitrous system and I have been told for 12 months now that it wouldn't work that way. Jeff responds to my inquiry and in two or three posts we have it all figured out. How's that for teamwork.

I must now e-mail Ryan Scott and ask to be included in the F/I shootout he wants to do for an upcoming issue of RX Tuner.

Let's put our brains together and start kicking out some REAL h.p. figures.

WTF?? http://www.mazdamaniac.com/images/smiles/icon_eek.gif

Yeah during our Photoshoot for RXTuner, I noticed some smoke coming out of the vent we couldn't identify where it was coming from so we opened up the engine bay and assumed it was some tape that was peeling off due to the heat and touching the exhaust manifold (things were getting very hot, the fork that holds up the hood burnt my fingers). John musta noticed it again when he took it out for a ride the next day and seen that it was the emanage box.

Jeff you have an AIM sn I need clarification on something.

AIM handle: o0oCrazyPolako0o

Just an aside, I ordered my E-Man with the E-01(as opposed to the Profec) and the guys at MOHD said that they also heard the rumors about discontinuing the E-01. The called GReddy and were told that they are not discontinuing it but they are on backorder and should be here in the next few weeks. Those not interested in boost control can still save a few bucks and get the E-01.

Between traveling, work and the weather I haven't really taken my 8 out since the turbo was installed. Went out with my mechanic today and OMG :eek: what power :D

My question is .... the boost gauge is showing peak boost at 11 psi -- isn't this a little high? I though it was pre-tuned at like 5 or 7 psi. My mechanic tested the gauge and it is accurate. The car ran GREAT but I am concerned about the boost level -- should I have it adjusted down to 7 or leave it as it came from GReddy?

P.S. After checking the hoses, etc. we took it out with a boosted S2000 he has that has dyno'd at 320 WHP and they were pretty even on a couple of informal stoplight runs.

Wow, that's good & bad.

Good : Lot's of extra power
Bad : without proper support (more fuel) you may blow your engine

When I put my kit on my gauge told me I was in line with what greddy was telling me I should be at (7 psi/5 psi at peak), but I was only getting 40 whp. There was something wrong, so my mechanic put his own boost gauge on & found I was only running 4 psi across the board (my gauge was not correct). On adjusting it to 6psi/4 psi at peak I was up to 52 whp increase. These kits need adjustment & tuning. I am bringing my car back in a week to get the boost turned up.

I'm not sure you can turn it down (mentally speaking), but I would get some bigger injectors & probably a boost controller, not to mention probably looking at the fuel maps from greddy.

yes they do

anyone know that this is cant find any information on the greddy site, also any one have any information about the "NEW" e-manage v2 that is comming out
RPM SIGNAL ADAPTOR 3 RX8 ADPT. 15900909 $23.00

The RPM signal adapter is included in the turbo kit.
It creates the RPM signal that the E-Manage needs from the coil signals.

thank you now i dont have to order it :)

kit comes with everything you need

Well, if you're running at 11psi, you would need to flow something like 75% more fuel than stock since you're adding 75% more air.

Is the stock fuel system able to do this?

Has your mechanic or you checked your AFR to make sure you're not running too lean? If not then you might be ok..

9 PSI is all you can do at 9000 RPM.
However, at 5000 RPM you could do 11 PSI with the OEM injectors maxed.

Not a good idea.

What is the limitation, the small turbo?

Not a good idea.

I suspect it is limited by the amount of fuel the injectors can deliver in their duty cycle.

On my Vortech-enhanced Mustang, the system managed the additional flow requirements by increasing the fuel pressure (by a ratio of 8lbs fuel to 1lb of boost). This worked well, up to a point, where the injectors would be unable to flow the additional fuel because of design limitations. Time to move up to larger injectors (which are rated in lbs/hr, not CC's).

This is a very simple conversion. You can figure out cc or lb/hr from any injector. Here's a link to a calculator.

http://www.witchhunter.com/injectorcalc1.htm

Most are rated in lbs/hr but really it is better ti use cc's. This is because there are various weights for fuel. The specific gravity for gasoline runs from .68 to .73 or therebouts. Those are numbers I came up with when weighing gas for dyno input. So without having an actual constant to reference back to it would be better to use cc's. I know the Magnetti Merrelli injectors are.

Injectors are rated in Lb/hr in places that use Imperial measurements. Cubic centimeters per minute is used everywhere else.

Thanks for the link, Fred. That's a good one for my bookmarks.

haha damn us and our use of both measuring standards:( lol can get real confusing..great link thanks for the find Rotarygod:D:D:D

Nice!! Thanks RG!

(After re-reading it, I probably could have qualified it a bit better, like"which are rated in lbs/hr on Fords"...)

Just came across this site looking for my next toy! Sold my MR2 turbo and was thinking bout gettin an 8 and turbcharging it...Anyway, Im reading ur thread and look and see u are from my hometown! Then Im watching the video and there u go down 70 towards my house!!! Quite funny actually. The rarity of the exact car in my area is funny to me: small world. Just wanted to share...now back to the video (stopped it cause I was in shock)

^^^ Welcome to the group. That must have been quite a wake-up call!

Thanks, sure was! The best thing of all ..... that was my same area where I used to take my 2 and rip it! Gotta love those jersey backroads! It would calm me down after the most stressfull day, miss it! Gotta do something about this. Do they make a white 8?

Hehe.. so you're from close by huh? Sweet deal.


And yes, they do make a white RX-8

Philodox on your site it has a link to download the install instructions, but it doesn't work, does anyone else have a digital copy? I want to see how hard the install is.

It's a 993KB PDF File - I have it

I'm sorry.. having trouble updating my site. Apparently almost every link is broken and not working.. ugh.. I'll try to get everything back up this week

Got the support tool, and hooked it up. Says my firmware is 1.42. Hmmm...well, dumb arse that I am I attempted to load the configurable "stock" GReddy map...and after I committed to clearing the old map out, decided it couldn't communicate with the emanage anymore.

WTF is up with this? How are folks getting the GST and emanage to uplink?

http://www.mazdamaniac.com/pdf/rx8_greddy_kit_instruction.pdf

Thanks, Jeff...I'm sorry. I wasn't very clear (read: frustrated).

My current problem is the eManage can be monitored in realtime, but will not read or write any maps. So, my eManage is now cleared, and empty.

I'm running 1.13 on my laptop...gonna try cooking up a hybrid (Jap/Eng) 1.2x version and see if my car and laptop can get along.

:(

Sorry if this was covered in another thread but will your 8 pass New Jersey inspection? I looked over the .PDF of the install instructions and Greddy notes that the kit is not “Street Legal”


My next inspectton date for my RX-8 is July 2008. I'll worry about it then ;)


I'm confused.. on the top of the greddy page under 'Bolt on Turbo Kits' it says:
(CARB E.O. # D-397, D-397-3, D-397-7. Contact GReddy Performance Products, Inc. for details)

My assumption would be that their CARB legal in CA. Which means they're street worthy applications. I e-mailed Greddy to be sure. The reason being is I live in CA where we get hit hard when put these goodies on and 'One tyme' runs up on us and makes us pop our hood. *sigh* Not to mention it just won't striaght pass smog and we'll to pay someone a kidney to smog it for us otherwise.. Anyone got any light on this?

If this was already disscussed sorry. I got to page 25 after trying to read up on it and decided to post it up after realizing there was 100+ pages . =P

That may be a blanket statement from GReddy on their products...but I have never seen any information stating that the RX-8 kit is CARB legal. In fact, there is a statement at the end of the installation instructions that basically says the following (if this paste works, that is):

"Important!
As of 12/30/04 this kit is not a street legal kit. Please ignore the label on the
e-manage."

Whew... :D

I have created a hybrid version 1.24 of the support tool (menus are in Japanese and illegible). The eManage and laptop can exchange maps freely now.

I went for a quick spin around the fringes of the neighborhood and noticed when coming to a stop, the idle would hang around 2K for several seconds, then drop to a smooth 850-ish RPM idle (@ 1.06 to 1.08v). I had the laptop monitoring, and could see the MAF voltage moving from .6 to 1.2 range...then it would settle down. (I don't have my CAN setup yet) When I pulled back in the driveway, the temp gauge caught my eye: it was dead. :eek: I pulled into the garage and sat letting the turbo cool, saving my run data. I looked back at the temp gauge and watched it come right back to life. :confused:

I have never had any gauge glitches or other odd behavior before, so this startled me a bit. I'll be tugging on all the plugs in the engine bay in the morning, after it cools down.

that happen to me once i think your car is not tuned right because i was having the same problem

What is the SST tool that the instructions refer to? And does it come with the kit? How hard was the BOV and Boost gauge install? Also is anyone running a boost controller?

I'm runing the profec type S boost controller.
We like it because is easy to tune it............

You will need something to hold the engine up since the right engine mount will be removed. No it's not included in the kit. They're probably referring to an engine lift (1st pic), but I used a high jack on the transmission (2nd pic) while it was on the lift, or you can use a regular jack if the car is on jackstands.

You'll need a shop that does aluminum welding to put on the BOV flange, then just tighten the 2 bolts and connect the hose.
The Boost gauge is fairly easy. Route the hose and wire through the firewall and then wire the power to it.

I've got the GReddy Profec B Spec II boost controller. Using it to limit the boost spikes right now.

that happen to me once i think your car is not tuned right because i was having the same problem

TTT: Your temp gauge was going dead, too?

Thanks for the help. I am thinking about going with the Profec E-01 it looks and cool and seems worth the money, replaces boost controller, boost gauge, laptop for editing emanage and it you can view things like A/F ratio. I noticed a couple people like Mazdamanic are using it.

What's the difference between the greddy Type-S BOV and the Type-RS BOV

Yes JoeMamma, ttt's water temp gauge was reading C then normal but It was a connection issue at the sending unit. The running condition did not change with the gauge fluctuation. If the run condition changes that sounds more like water thermosensor problem...Scott

Well, I got the Greddy Type RS BOV and the GReddy Profec E-01 yesterday, now all I have to do is get the actual kit.

Guys, I've recommended before.. and I'll recommend it again. The Type-S is the way to go. It's rated for low boost systems which is what the Greddy Kit is. Correct me if I'm wrong, but the Type-RS is for high boost applications.

That's interesting. According to the service manual, the ECT (engine temp) signal will create excessively rich mixtures and a fast idle, like mine. I didn't see a thermosensor mentioned.

Well, the guys at Vivid Racing are running a type RS and they love it. I belive it goes type S low boost, type RS intermediate and type R for high boost. But all should be able to be tuned for any setups. The RS should just be louder and capable of standing more boost.

And you're forgetting more expensive :p :p :p :p

Yes it is more expensive. But not by much I got mine brand new in the box for $150 dollars on ebay which the Type S was selling for $139.

Kurama Motoring? That's the ebay vendor I buy all my Greddy stuff from. Cheapest prices on the planet for new stuff. He's the one I got my Defi BF gauges from as well.

Any chance someone with a Type RS could post a sound clip? I'd like to hear the difference between my type-s and the type-rs.

There is some website some where with loads of sound clips of all most every BOV but I forget the URL

I was reading in the CZ thread and noticed this post from Maurice -- Does this mean anything for us with turbos? Will the ECU "learn" and fight against our tuning maps?

Some of you who are tuning have posted that the car ECU "learns" a long term fuel trim and adjusts against the tuning.
You are right!
BUT:
The car checks AFR when it is in closed loop mode.
That is below 70% throttle, and below the closed loop/open loop transition rpm.
So, what IS the transition rpm?
By measurement:
1st gear: 6,200rpm
2nd gear: 5,500rpm
3rd gear: 4,800rpm
4th gear and up - same as 3rd.

So, some lessons to derive from this:
1) Tune above transition point ( 6,200) and do NOT touch the fuel/air below 6,200 unless it is only 5% or less.
2) If you want to tune down to 5,500 avoid full throttle in 1st gear below 6,200
3) If you want it tune more, and want to get around the "learned"long term trims, simply disconnect the battery ground if the ECU "learns" a fule trim.
This returns the car to default fuel/air settings.
Of course it will "learn" again, so this is not a long term solutiion.
I installed a replacement battery groundpost that has a 1/4 turn knob to disconnect. This allows for quick and easy resets.

Also, regarding weather and temperatures:
If you tune in cold weather the air is denser.
When you run at a higher temp the air is less dense.
That means the mixture will be a bit different.
Humidity will also affect it.
The car has a barometric perssure sensor as well, so it does compensate for altitude and air pressure change due to weather, however it does not have a means for detecting humidity.
My advice, if doing fairly aggressive maps is to do a set for both cold/dry conditions and for warm/wet ones.
Save them and use as needed.

You know this was very early in the ecu development days for this car. Alot has been learned since then. Personally I find it to be a complete waste of time and money to only tune a car above 6200 rpm. This car actually needs the most help below this point. You can clearly see it on my datalogs of the stock maps. The stock ecu can be tuned like every other one. It just needs to be dealt with in a little different fashion. Personally I don't think the Canzoomer/emanage is the right tool for the job but that's just my opinion.

You know this was very early in the ecu development days for this car. Alot has been learned since then.

RG -- Maurice just posted this a few weeks ago. I agree that tuning only at the very top end would be worthless. What I am concerned about is -- will the ECU really "learn" and then adjust? and will it negatively affect our tune -- I assume it will if it "trims" fuel.

assuming that the ECU adjusts below this RPM, or learns, wouldn't Greddy also know this fact? And if so then just see what there maps are like and what it looks like above and below this transition point.

Greddy wires up the emanage differently from how Maurice does it as far as I know. I thought Jeff (Mazdamaniac) said something about this. If this is true, it could explain alot about how the ecu fights back or not.

I ran into the trick GReddy is using to kick the ECU into open-loop on my kit after I loaded the unlocked eManage map that was posted on this thread.

My car would have a dead dashboard temp gauge, fast idle (~2k RPM) for 5-10 seconds, then quickly settle into a proper idle after the gauge came back to life. This was caused by one of the "dongles" on the GReddy wiring loom that controls the ECT (engine temperature sensor), switching it "out" when it needs to richen the mixture and put the ECU in open loop and keep it from pulling out the additional fuel. It's a simple and effective way to get the ECU out of the way, but has the odd visual side effect of dipping the temperature gauge when in boost at low-to-mid RPM ranges.

It doesn't work on all cars, either. Some will have lean issues and bucking as well as preignition and odd LONGFT numbers.

I've been suggesting that people that have issues like these, to disconnect the dongle from the harness.

Longft?

Long term fuel trim.

what would a weird number be for longft?

Less than %5 would be ideal. 3% or 0% is awesome.
14% to 17% or more is a problem, but not uncommon in some "tuned" RX-8s that I have played with. This is not good.

Mine hovers around 5%.

what about negative numbers?

I think (may be wrong here), that negative LFT's indicate the PCM is subtracting fuel (rich), while the positive numbers mean its adding fuel (lean).

On the 6's, the injen intake threw off the maf sensor so much, everyone pegged out the LFT's at 20.3%. =/

Sorry, those are negative numbers.

Question guys, my EGT gauge is reading about 710deg C for my exhaust gas temp. It gets that hot when I am driving hard. Is such a high temp something I should worry about? Normal drving n the street I am around 550deg C.

philodox i'm not far from new jersey hopefully sometime i could go down and check out your turbo 8 before i think about going turbo with mine.

710°C (1310°F) is not that hot at all, especially for a rotary motor.
I'd expect temps as high as 870°C to be normal. It is possible to see temps as high as 1000°C!
Since there are no valves to burn on the rotary, it isn't much of an issue.

EGT is only useful relative to maximum torque. Only once you have established what is the "right" number for your motor on a dyno can you use EGT effectively.

I would opine that rotaries' EGT's are higher precisely BECAUSE they have no exhaust valves which tend to carry away a large portion of the exhaust heat in piston engines. MM is right on the mark with regard to finding which numbers your specific engine operates best with and tuning to that, be they EGT's, A/F ratios, timing curves, or coolant temps.

Ah, so I can probably lean out my A/F a bit more then since my EGT is so low when I am really pushing it?

Possibly. It really comes down to how lean you can go and 1) create more power and 2) avoid preignition.
Rich is relative. 11:1 may produce the most power. 12.5:1 might be better. You need to do it with repeated, identical runs either on the dyno or on a clear track/street where the only thing on your mind is A/F (not collision avoidance).

The other issue is resolution of the E-Manage. The inherent resolution is fine, but the Greddy MAP (mine as well) is set up to address certain RPM ranges with fairly fine control. That leaves other range windows to be somewhat wider. What you do in one range affects another so you may not be able to reduce the fuel in one range without causing the next to be too lean.
Just move in small increments and see what happens.

Best bet is to have one person operate the Support Tool while the other drives.

I wanted to come back to this for a second as I'm trying to tune across the RPM band with my CZ box. I haven't seen the turbo wiring harness, is this "dongle" a seperate cable from the emanage that goes directly to the temp sensor? In other words, its not part of the wiring that connects to the ECU?

My CZ box has three big white connectors that connect to the stock ECU as a pass through from the stock cars sensors, so I'm trying to figure out if I can augment my wiring in a similar manor.

why does messing with the temp sensor trick the car into open loop all the time?

The PCM runs in open loop when the coolant temp is low.....so tricking the PCM will switch it to open loop. The only problem I can see...is what else is it doing at the same time.....ie timing, rev limiting etc. Seems like a bastardized way to deal with this??

Ok, I see. Well, I've logged the car at startup on canscan and I didn't see any wierd ignition advance or other wierd events, other than it idles high for a bit then falls down.

So are you disconnecting the temp sensor wire all together or connecting it to the emanage for the emanage to fool the computer?

The dongle passes the regular temp signal through until it is triggered by the "VTEC" map in the E-Manage.
At that time, it substitutes the temp signal for a resistance that is equal to about 160°F, fooling the ECU into thinking the car is warming up.
Not really a particularly elegant solution and, as noted earlier, one that doesn't work on every car.

FWIW, I had a similar signal modifier on my Miata for a few days back when I was experimenting. It didn't like it very much.

Jeff, out of curiosity...how did you deal with this situation when tuning for your turbo? It doesn't sound like you used a "hack" like this. How about when you were helping some of the GReddy guys for whom the base map wasn't working...did you work with this, or did you trash it and do it differently?

No hack, just straight fuel injection control.

For people with the bucking/lean running/preignition issues, simply pulling this box and retuning seems to fix the problems.

I was told my turbo is gona be in this week. getong guages/turbo timer installed now awaiting the 2 great boxes to arrive any tips when it is installed gona be done by the same guy philodox used. i have a uneque set up for the guages i will post pic when i get it..

I am also gettin my turbo, guages, type Rs-BOV, catchcan, oilpan and turbo timer ... i am gettting my kit on april 6 wich is a wensday and we will be doing the install that weekend ....... me and my brother .... and yes he is ASE cert. and all that good stuff and has a shop to do it at no jack stands ...... But i will take pics and post to let you all know how it goes..... hopefully it all goes well .......

I'm not sure of the distinction, but the new map I received has NVCS selected, not VTEC. Does this just use another control wire, Jeff?

Same wire (yellow), same MAP, different name.

Hey Philo. How many miles do you have on your car since the turbo install? Have there been any changes to your routine (adding oil, gas consumption, issues etc...) over this time?

Miles Since Install: 1750miles

Fuel Before Turbo: 12-13mpg

Fuel After Turbo: 14-15mpg

Oil Consumption: Nothing speciall.. same as always

Other Issues: Nothing worth mentioning.

Great to hear! What do you plan on doing when your next inspection is due? Think you'll pass it as is?

Great to hear! What do you plan on doing when your next inspection is due? Think you'll pass it as is?

lol.. my next inspection isn't due until July of 2008.. I'm not worried about it.

Here is the updated GReddy map (3-4-05 date) that they sent me yesterday -- of course you will need to save and change the file extension to .GSC

Looks like they made some mid-range adjustments and VTEC adjustments?

If your support tool is too old a version to use the new maps -- here is the update that GReddy sent me.

Benny's instructions:
You`ll need to open the zip file 122-142. The new support tool file will be called Project GSC. Open that file, and while online, click on the open file tab and select the RX-8 03 04 05 3 file. After it displays, you`ll need to click on the export data to Emanage tab on the upper right side. After that it should upload the data to the emanage. Thanks for choosing GReddy Products.

EDIT -- Oops the file is too big :( I guess if you need it PM me or ask Benny for it directly.

BTW - my tuner actually used the 2_20 base map that MazdaManiac posted rather than the GReddy map when he dyno tuned yesterday. The GReddy map was running SO rich (AFR's in the 9's) and the dyno plot was very jumpy. Jeff's map with some tuning to a conservative 10.5 to 11.0 AFR @ 7.0 lbs of boost got me to a peak whp of 246.

In 2nd gear at WOT this thing leaps like a rocket taking off :D -- and yes I know what that feels like -- I have been in the space shuttle simulator at NASA :cool:

In 2nd gear at WOT this thing leaps like a rocket taking off :D -- and yes I know what that feels like -- I have been in the space shuttle simulator at NASA :cool:

Schweet!!! Gotta appreciate Jeff's hard work!! ;)

Well I still get a cel for the secondary injection. I have tried both gaskets. Nothing is working on my car. :(

Which map are you using? The base map that came with the emanage? The only CEL I occasionaly get is "random misfire".. but my plugs are fine and it happens once in a blue moon... nothing to worry about.

Hey Jon....I think I remember you saying you were going to run the turbo for a while and then do a partial/full tear down to check things out. ( or was it to do something else?) Still planning on doing that?

Which map are you using? The base map that came with the emanage? The only CEL I occasionaly get is "random misfire".. but my plugs are fine and it happens once in a blue moon... nothing to worry about.

I am using one of jeff's maps he tuned me for on 7-8 psi but I am only runing 6psi up top and it bleeds off to 4psi. I am still trying to figure out the Profec EO-1.

Also the random misfire is from running very rich.Jeffs maps have some rich spots. I still get that random Mis fire code but you now when you get it because the car feels real slow and hesitates because of the richness.

Yeah the Profec is not an easy thing to figure out -- one of the most confusing is that you don't set the boost level (eventhough it allows you to set boost level for hi and lo -- which makes it even more confusing and apparently does nothing) -- you set the duty cycle which in turn controlls the boost.

Mazda Maniac. I'm Just Wondering Why You Haven't Replied To The Private Message I Sent. For Those Of You Out There Reading This. I Was Wondering If Anyone Has A Bunch Of Different Maps For The Emanage. I Already Have Two Different Ones That Greddy Sent Me, But Was Hoping If Any Of You Made Better Ones?

I haven't seen Jeff post any MAPs since this one (it is very hard to find so I will post it for you again).

Thanks RXHusker. I believe I have already seen that one, but when you look at the graph it looks identical to one of the Base Maps Greddy sent me. Maybe Greddy used Jeff's.

I haven't posted any new MAPS lately, but I did just noticed that Greddy is now distributing my last MAP that I made public.
Very interesting.

Yeah the Profec is not an easy thing to figure out -- one of the most confusing is that you don't set the boost level (eventhough it allows you to set boost level for hi and lo -- which makes it even more confusing and apparently does nothing) -- you set the duty cycle which in turn controlls the boost.
Sort of.
You set the "Set Boost" parameter to a percentage over the mechanically fixed opening point of the WG actuator, then you set the "Start" parameter to 2.8 PSI short of your target boost.
Then, you adjust the duty cycle to control how tighly the boost is held without over-shooting.

Sorry, I've been out on work quite a bit the last two weeks. I will be gone on and off again for the next two weeks as well.

Here is my last MAP again, for those that want an intellectual excersise - it is the same as the current Greddy MAP, only with ignition timing (the turbo kit is not wired for this, so they deleted it), no "VTEC" because I don't use the open-loop fooler module and shift-surge fueling suppression (I don't know why they deleted this - it works).

does that mean that they are using your tune in their new "upgaded" maps or just giving out the info in your map. (i suppose they dont give stuff like that away,,,i think i answered my own question!)

Jeff -- give us your latest and greatest :D PLEASE :o

Can you copyright those and send the bill to GReddy ;)

Seriously we all appreciate the time and certainly the expertise you have shared on the forum.


EDIT: You posted the MAP while I was typing -- thanks! I assume I should unplug the little black box to run this MAP

I haven't posted any new MAPS lately, but I did just noticed that Greddy is now distributing my last MAP that I made public.

One thing is sharing your maps with people to use on their own cars and another is Greddy using it to get profits out of it... I'd give them a call ;)

Me: Hey! I just noticed you are shipping your RX-8 turbo kits with my fueling MAPS.
Benny: No we're not.
Me: Yes you are. I spent hours on the phone and in the field with you and your customers and now I see your add injection and sub injection MAPS are a direct, cell-for-cell copy of my last "published" MAP.
Benny: No its not.
Me: Yes it is.
Benny: Even so, what do you want Me to do about it?
Me: Compensate Me for my work in fixing your companies problems.
Benny: Why?
Me: Because! It is the right thing to do.
Benny: We don't have any sort of contract with you. Too bad.

That just sounds like a greedy A$$4013. If I consider to turbo that kind of attitude makes me want to look elsewhere. SSR is looking better every day.

That just sounds like a greedy A$$4013. If I consider to turbo that kind of attitude makes me want to look elsewhere. SSR is looking better every day.
However, the Greddy kit is very well built and far more bang-for-the-buck and you can get one now.

Who is this Benny guy? How high up the food chain is he? Maybe there is someone else you can talk to that has less of a case of assholeitis.....

Wow, That don't sound like Benny to me.. Mazdamaniac what kind of compensation where you thinking about, How much, maybe We greddy turbo owners can pitch in to help you for your work . I will never have a problem compensating someone who has helped me..

Benny is a tech. rep. from GReddy. Many people complain that GReddy has horrible customer relations but that is because they don't do customer relations. Instead, they prefer to service their dealers and let the dealer network worry about the end-user. If I were in their position I might do the same. If you take a look around this very forum you will often find people in a little over their heads when it comes to their mechanical abilities conflicting with their desires. In other words, they sometimes don't realize that they don't have the education necessary to perform certain mods like, say, a suspension spring swap. When they end up with a driveway full of parts and no idea how they go back together they then come on the RX8Club and ask for emergency help. How would you like to deal with these situations all day long? I feel dumb, myself, because I am not quite up-to-speed on the E-Manage deal and I sorta feel bad for asking MM's help but the prospect of getting that elusive 20 h.p. and the ability to reach higher levels of nitrous boost seem to assuage any feelings of inadequecy I may have.

CRH

Settle down folks, i'm pretty sure Jeff said " Oh, I can see that call." Meaning he didn't actually get that response.

Well my trubo is done ... i am waiting for the 02 sensor .... B/c we stripped the stock one .... but question ..... my DSC and my tracktion control will not go off ..... anyone know why ??? thanks Shane

That's why GReddy prefers to service the dealer newtork and not every person out there who is over their head in the mod game.

Do you mean the warning lights won't go off?

If so -- try disconnecting the battery (pump the brake a few times to clear) and then you will need to restart twice and the lights should come off.

The steering angle sensors need to be reset. With the car on, turn the wheel all of the way to the left and then all of the way to the right. The next time you start the car the lights will go out.

Sorry Jeff, I didn't mean to open up a can of worms! The only reason I decided to look at each individual cell was because, When I was taking the three different Fuel Maps for a test drive, Two of them felt exactly the same(Yours and what greddy gave me). At first I just thought that I had named the MAPS incorrectly when saving to my PC. But when i opened it up, I was just confused. Oh well I thought, and left my emanage with Greddy's just to be on the safe side, but now I know who really made it.

Any way, I find this map to be better on fuel, but it also feels like it has less torque under WOT on second gear. However, with this map I can Keep up with My brother's modded 2004. SRT-4 which might I add is FAST! I could totaly take him on first, But on second he catches up. On a guestimated quarter mile length he'll beat me by about a car length.

Oh just FYI!!! With the Greddy Turbo kit, we can take any stock SRT-4. My best friend has one as well and he just can't catch up =) ( he is boosting 14 pounds )

I haven't tried the map you recently posted, but I hope it does me good. Thanks Again Jeff.

Take my word for it, once you get that turbo kit running tip-top you'll have no trouble keeping up with stock STi's, Evo8's, 2005 Mustang's, Camaro's, GTO's, and the list goes on. With other mods like the light flywheel and whatever else you can afford a mere 6-7 psi will have you in the 12's. All this car needs is a little traction and we will rule the streets. The other night a stock STi ended up a car length ahead of me and I wasn't using the nitrous.

CRH

Well guys i am considering buyint greddy turbo kit but recently i heard from a very famous Mechanic here in Greece that 3 8s tried to install the greddy turbo,without changing anything,just bolting it in and all of them crashed the engine....It wasn't fault of the mechanic and nor fault of the guys...It was greddy he said...
Does anyone knows if there was an error of any batch of the greddy turbos???

And second..I have already canzoomer midp-4,waiting for my rb revi,ms flywheel,soon ms disc+cover,soon ms radiator,greddy sp2 catback,n flash i belive its a good basis for the turbo right???

Are you boosting as well?

I read the article in RX tuner by Philodox, how hard was it to transplant the screens from the stock airbox to the new intake, and does it still work/ solve the problem of rough idle? Also, I think I read that we had but have we gotten the Greddy Password yet for the emanage?

I am only using nitrous as the external power adder. I have all the other usual bolt-ons.

That guy in the STi was shocked as to how close it was. The good thing is that he didn't know me by appearance and I overheard him in a burger joint parking lot telling his young homies the truth about what happened. I want to develop a mysterious reputation because that's when the challenges and money are thrown down. Now if I can just get this thing as quick as I need it.....

CRH

Same here charles, i had an sti and neon both test me the other night and it winded up being me and the sti neck and neck . when we stopped he was like that things suppose to be slow, i laughed and smoked the tires, haha, these kids arent ready for this summer haha, fyi, broke traction in 4th gear, i almost crashed i was so surprised haha

Be careful out there, Boosted. I am glad to see that others are finding the true potential of the RX-8. One of the things I like about the RX-8 is that the "go fast" recipes for piston engines are well-known and frequently used, therefore no interesting conversation ensues. It's all same-old, same-old. You roll up to a scene and open the hood on your RX-8, however, and with what few mods are visible people will still gather 'round to look. I would imagine a turbo kit gets a lot of looks. People gather around my trunk to look at the shiny tank and approach me to ask about how well the nitrous works. Usually what happens is that I get asked about my mods while driving and I refuse to tell anyone. There are a couple bigmouths, bigger than mine anyway, out there who I want to blindside this Summer. Once I get into 12.7-12.8 range I'll start some serious "negotiating". I'll tell ya right off, going back to 26" tires cut those lost three tenths back off my e.t. I may now be back to running 13.3's(from current 13.7's with 27" tires) without nitrous like I was prior to storing the car last year. If that is the case, mid 12's are just around the corner.

CRH

CRH how old are you?

is it me or is this become a kills thread now..?

^^^^^
c'mon, I like hearing about these stories. As nobody has any official times on what a turboed (or nitroused) RX8 has done 0-60/1/4 mile time this is what we have to gauge our cars against. We put a turbo in our car because we want to go faster, nothing wrong with opening it up occasionally. No need to bust another posters's chopswith a snide remark about his age. If you don't like the post than don't read it.

I like subverted kills threads. I'd talk about mine if I had any worth mentioning.http://www.mazdamaniac.com/images/smiles/upbum.gif

Thanks for the backup, guys. Look, Fanman is right; why do we need to not only be banned from discussing how we discover the relative quickness of our cars but now it is being implied that we must also ignore or deny that fact that those of us who modify our cars do so for reasons other than the fact that we like to take discretionary liberties? I would hate to think that the RX-8 community is filled with people who think we spend $4,000 on a turbo kit just because it looks good. I would also hate to think that we are going to be so vanity-conscious that we cannot discuss driving to a desolate area and doing some G-Tech runs for the sake of measuring, in some way, the performance gains that many of us are interested in knowing. Fanman is also right about choosing content that is comfortable to you. I have made no secret on this forum about my particular project, nor what my intentions are. I do manage to mention in a veiled way how I make these vehicle-to-vehicle comaprisons, but the veiling is only to placate those lawsuit-wary website administartors. As far as my discussions being "kills", I thought the word "kills" implies by definition a win on my part. My most recent discussions have involved an STi beating me. How is that a "kill"?

As far as my age goes, I am old enough to have survived doing this for 25 years and never having been in an accident or other reckless compromise of the safety of others. If there is a situation that I think is a risk to others or myself, I will turn down the challenge and seek to modify the conditions under which things take place. If that means telling the 200 people who wish to watch to leave, that's what it takes.

What I find a hypocrisy on part of others around here is that when it comes to discussing the results guys like myself and MazdaManiac get out of our cars, everyone wants to congratulate us and ask us how we did it and what might work for them. When we discuss the environment in which certain mods are proven out, some of those same supporters want to preach about our methodologies. Some people cannot deal with the way their favorite sausage is made or the fact that their favorite foods involve the killing of animals.

How ironic.

For anyone who wants to see where this could all lead, read the novel "Atlas Shrugged" by Ayn Rand. The second-handers need to quit being distrustful and critical.

Wednesday I'm gone, but I'm sure I'll be here on the forum all of next week from Las Vegas.

Well guy's, Today I had my cat and resonater completely removed , running complete custom straight 3" pipe pretty much from the Greddy turbo all the way to the my custom magnaflow mufflers at each exhaust port. I'm not sure how much horse power I gained. but you really do feel some more torque once boost kicks in. And for those of you who worry about the sound, its not that bad. What is bad is the Back Fire. (It sounds like someone is shooting a Shot Gut from your trunk :eek: . The car rumbles at idle nicely and isn't real loaud while cruising on the highway. If you have turbo. I recommend it.

Well see how things go when I take my brother's SRT-4 tonight :D

Additionally, I wouldn't come down hard on XeRo because he didn't necessarily mean the administration as much as he may have meant the way some members like to police the posts made by other members. In that case I would invite those members who wish to police others to become moderators and when they begin deleting certain posts and threads, we'll see who sticks around and puts up with it. Let the free market decide, if you will.

I have no complaints about the way you and other moderators have treated me but it seems as if some may feel that preferential treatment has been handed out. Since I cannot read every single post on this forum, nor would I want to, I have no response if that is the case.

On another note, I humbly request that everyone please get back on topic. Please save the spamming personal opinions about non-related issues to PM's or another thread.

i will start. regarding the hi flow cat from SR...i have been having terrible problems with backfiring and unevenness of vacume/boost transition...(as has philidox and others.)
no one has mentioned the SR cat so far but maybe that is an issue.
MM has suggested that i bypass the temp sensor "fooler" (see pict).
i am truly stumped and wonder what is the next step might be. can i get a decent tune on this (leaner and cleaner and smoother) without becoming a computer expert?
philidox, if you have any suggestions since you had the same issues, could you PM me? i PM'd you a day or two ago.
thanks

Help,Quick question if anyone is out there. I know it's in this thread somewhere , but I don't have time, I'am working right now installing Greddy turbo,

Are we supposed to use our original air pump gasket into the greddy exhaust, or use the one supplied in the kit...

SHIT i just bought the sr cat flow i should be putting in next week when i take my car to jr
i will let you guys know how i do.

you might have wanted to go with the Rotary Performance one...:)

i have read this thread from the begining. use the gasket on the car. not the gready

Use the factory gasket for the air pump. The greddy gasket will give you a CEL for secondary air flow.

Well with a straight thru exhaust my car could not control boost. So I don’t recommend doing it. Mazda maniac does not have an issue but I did. Also I welded in a high flow cat in my mid pipe and really makes the car sound stock and still has the power:) Still got the cel for the damn air pump. I am probably going to remove it soon. I don’t give a shit about emissions so less shit in the engine bay the better.

-Ryan

Also, Jeff & I removed the dongle on my car a few weeks ago and it seems to work real nice with out it;)

Rudy mailed me to ask for labor help with his particular problem of boost and A/F ratio control. Is it too much to ask you guys to re-cap a couple of pointers for us so when we get together to fix his problems we have some solid info to guide us? That would be appreciated.

Thanks,
CRH

Biggest thing on the greddy kit is get a cat of some sorts it needs backpressure to control the boost. That was alot of my problem when I got the kit on. Now it is great! Jeffs maps are real good. So down load the latest spec from jeff and dial her in. I would tune from11.5.1 to 11.8.1 on a baileys wideband. Remember all widebands are different so this number is only good for the baileys and maybe an FJO. Dont trust that can scan it does not go to the range it needs to be. All cars are DIFFERENT!!!!

Also F! the dongle!

Hopefully this will clarify rather than confuse:

So this will solve the problem with the High Flow CAT? What does the dongle do normally?

it does something with the vtec and temp sensor to the stock ecu if I remember correctly!

So this will solve the problem with the High Flow CAT? What does the dongle do normally?
This little black box tries to force the car into open loop at 1200 and 4900 RPM - points at which the RX-8 PCM tries to operate in closed-loop, even at WOT.
It attempts to accomplish this by fooling the PCM into believing the coolant temperature has suddenly dropped below 160° in those RPM ranges.
This doesn't work on most RX-8s.
It has nothing to do with the CAT.

BTW - I'm thinking about putting my CAT back on. Not because of boost control issues but because of smell.
When I start my car in the morning, if I don't IMMEDIATELY back it out of the garage, my whole house reeks of exhaust fumes for hours.
Even stopped at a light with the sunroof open yields watery eyes.

I didn't notice it so much in the winter...

Rudy and I will keep an eye on this thread as it continues and employ your suggestions if, and when, we get together to sort it out (if he still need my help after all this). Thanks for the specific A/F ratios, Ryan.

CRH

If all goes well I will be hitting the dyno at PFS and turning the boost up this weekend!
I hope it works because I am looking at running 10psi!!!!!!!!!!!

Just an FYI! moments ago I hooked the dongle back up and the car runs like shit! rough idle,crappy shifts, and so on. Get rid of that hunk o hunk o sheit!!!!!!!!

just wonder how long would it take a decent rotary shop to install the greddy turbo i'm highly considering getting one.

I know it was posted before but what is the dongle and how hard is it to uninstall...

I highly recommend removing it, but only if you are having issues like Ryan here.

Jon's car (Philodox) has no issues. We just installed the newest MAP in his car with the dongle still in place and it runs great.

I have the newest map from greddy Installed, and i had to put the cat back in I orignally had the bonez rp midpipe, the car was runnin almost 8lbs of boost but it was soo choppy and i could not solve the lean issue at top end, but now im pissed cuz boost dropped to 5 lbs, until i have have some $ to solve fuel issues i think im gonna keep the cat on, I NEED SOME ADVICE ON WHAT TO DO TO GET MY 8LBS OF BOOST BACK, SOMEBODY! LOL, and have a smooth running car, with Less of that innoying backfire,

oh i seee ...... thanks jeff

Yup I had the same problem on my car. The wastegate is just too small. Needs some BP to keep it under contro(high flow works great)l. I will be turning up the boost this weekend :eek: so I will share what I learn after that.

I also noticed my peak boost dropped after I received my emanage back from Greddy with the updated map. It used to be 7psi (48kPa) but now I'm only getting 6psi(42kPa).

The E-Manage MAP shouldn't affect the boost numbers at all unless the engine is simply putting out WAY less power and, therefore, exhaust. This would be bad and unlikely.

The E-Manage has no provision for boost control.

dood, your avatar scares me!

Also outside air temp can effect boost:) :o

i jsut wish my O2 sensor would come in .... i miss my car .....

That is true. Forgot about that.

Yup, she's fit as a fiddle. Thanks again Jeff for loading the new map for me. By the way.. I got 21mpg on the ride home from your place.. You didn't tell me your map would give me 5mpg more on the highway :)

That is true. Forgot about that.

Jeff where have you been hiding man. Like to hook up with ya!
Call me :D

dood, your avatar scares me!

Hehe, you should see his dog in person.. I'd rather face a rabbid rotty than that beast!

Yeah I Had the midpipe on there, so basicly i should get the high flow cat? and by the way my gas mileage sucks really bad id be surprised if i get 12 miles per gallon, thats rediculous any way to help that, and wats this dongle thing?
