Blew my motor. Was running the greddy turbo kit with Agency power cat-back tuned at 9 psi making 293 whp. Made 256 at 5 psi. No driveability problems what so ever after the tune was turn key daily driver running emanage ultimate. Suspect the emanage lost the tuned map after key reset. Was romping it skating the rear when it let go shifting from 2nd to 3rd at 9500 rpm. Acually still runs but have little compression on the front rotor. Am a Audi tech by trait. Found 3 of the 4 spark plugs not working....lol. Replaced. So now car runs like crap like 60 seconds at wot to get to 60 but no check engine light anymore..haha. I just though i would tell my story kinda sucs. Im going to sell the turbo kit(only 3200 mi) get a used dropout and port it already have re headers and ap midpipe. Prob get a Rb intake and just run it like that 220-250 whp. May also run a shot. What do you think?

Sounds like you should have replaced your ignition coils.:(

sucks to hear that...those where some respectable numbers my recommendation is still run the turbo kit on the next motor with a different engine management such as interceptor or cobb ap @ 5psi

Blew my motor. Was running the greddy turbo kit with Agency power cat-back tuned at 9 psi making 293 whp.

What do you think?

I think it's unlikely you made 293 whp on 9 psi with the greddy turbo. You would usually need in the neighborhood of 12 psi on the greddy for that.

Where was the pressure measured from?

Coils check ok plugs were bad open on center electrode lol knocked out 3 of the 4 plugs it detonated bad

i did that turbo wont run 12 psi lol well itll spike. The cars on meth it needs it but it make 293 on 9.x psi its dyno # its all relative (basically dont mean anything so who cares)

Pessure on dyno greddy sensor was i think .03 higher or something like that so mabe like 10 psi

Its either going na or alot higher than 293 whp that was numbers on the first and only tune

OK, if you have meth and other stuff, then it might be possible, but out of the box the greddy kit makes maybe 230 whp. 9 psi usually makes in the neighborhood of 270 whp. You can go to around 12 psi, and that will make around 280-290. If you measure the pressure at the turbo, it will read high. Reading it at the intake manifold will give you a lower number, but it's more accurate on what your engine is getting.

Spiking isn't an issue, you just need to configure the boost controller. The issue is the greddy turbo is crap, and wears out after 12k miles most of the time. Also it can't feed the engine enough air over 7k rpm. Look at getting the MM turbo upgrade as the charge temps are cooler, so it's safer to run.

yea running stage 2 snow meth and a catback and geddy kit car is bone stock other than that and has stock cat/midpipe. I run a hallman manual bc anything over 9 itll spike and settle just the nature of the turbo wastegate exaust flow. 293 whp is respecatable with the greddy kit and it blew the motor most likey cause greddy emange sucs lol.

If the car stays turbo. Ill run the greddy kit with a gt3076r (manifold,downpipe custom w/ external wastegate) Also different fuel pump, injectors more meth and different management not AP...haha)

and different management not AP...haha)


Yeah, no sense in doing things the right way this time around.

ok whatever not tunable to me is no good have fun with ur mail flash

seems to me he is thinking about it correctly

ok whatever not tunable to me is no good have fun with ur mail flash

There hasn't been a single person with a blown engine from the AP. I don't think anyone has even reported detonation.

Meanwhile you're like the 9 billionth blown from using the emanage.

seems to me he is thinking about it correctly

Are you going to qualify that with something, or just inject random statements? :)

ok well thats how everyones doing it i dont want to argue rx8 owners r usaually down what do u drive a mustang rx8

whats the point of the.. do it my way or the wrong way mentality?

0 blown engines that you know of on a tool that's been out for 5 months is not saying much.

Behind the tool is still a tuner (granted MM is a very knowledgeable and experienced one at that), doesn't mean no one else should try their hand at tuning...

whats the point of the.. do it my way or the wrong way mentality?

The AP is really that much better than anything else available for the RX-8.

There is only one justification for not using the AP at this point in time, and that is if you have a blow through setup that the AP cannot yet handle due to the MAF sensor. AFAIK there's only one turbo kit that does that.

We had blown engines with the greddy well within this timeframe. The install base of the AP is not minor. the cost of entry is so low and it's use is so widespread, it is not as insignificant as you make it sound.


I don't say this out of the blue for no reason. I've used just about all the piggybacks available for the RX-8. The AP is the proper choice, hands down, no question.

The street tune software should be out within a month.

I waited 3 years for the AP to come out. Him waiting a month isn't a big deal since he still has to replace his engine. But then again, I'm trying to explain common sense stuff to a guy who's biggest mod is a radar detector, and another guy who blows his engine up and wants to do it again.

:banghead:

When that comes out, I would be right there with you.

I'm not saying AP is not the most flexible, robust tool on the market today, I agree with you on this. In fact, my AP is in the mail and will be here in a few days. However, as of now, it can't be tuned which is one of OP's requirements.

And FYI, I like my radar detector mod! Plus I've only had the car for a few months, I'll take my time with turbo and such.

haha. I'm just playing. I don't want to come off as too much of an asshole, but I am speaking from experience with the piggybacks. Until the AccessPort, we literally were scraping the bottom of the barrel because each system available had major drawbacks and no alternatives regardless of price.

u say some stuff comes off offensive even if your joking kinda not funny lol......If Ap the best well ill go with it. im not trying to blow another motor this mistake cost me 3k and im doing labor myelf so.....Turbos fun and all but this motor is nice NA with the right mods and port may be really nice and then a shot on top to leave a turbo 8 in the dust.

Really? Well, I probably wont be able to tune it myself for a while. but thats a great news indeed ...

hmm ... I need to give an PM to MM :)

NOS FTL lol. I agree the cobb AP is a very nice tool. Hope you atleast consider it man. Also im sorry about your motor , hope you get it fixed soon. Were you running on the stock turbos on the greddy?

porting doesn't do much for the rx8 engine. Intakes are already huge, and exhaust can't be changed much.

NOS... well, it is cheap and will give you a lot of power compared to bolt-ons, but I don't favor that either. It gets expensive if you use it constantly, plus you have to take the time to fill it up. Not only that, but it's a set pressure. It's more or less kinda like the stock greddy turbo. That 7 psi worked nicely for a while, but as you go to 6, 7, 8k rpm, it's not looking so hot anymore, it levels off. Isn't this true? I don't have any NOS background, so someone correct me if I'm off.

It's interesting how much people want to hold onto the older tuning devices simply because they can tweak the tune themselves.

No, there hasn't been a single blown motor on the AP and only a couple people who have reported slight detonation but those issues were quickly resolved. The primary reasoning for it's success has been because people are either using tunes generated by MazdaManiac or the basic COBB tune which is too generic to cause any problems.

I'm sure we'll see a few nuked motors once the street tuner software becomes avaliable. I'd say unless you can afford to blow your motor it's best left to those who have already made their mistakes.

In my opinion, porting on the RENESIS doesn't yield (for me) the kind of power that would warrant the possible loss of reliability. Besides, the engine is limited because of the small exhaust ports. Porting the motor won't change the fact that you still have a small port to flow those gasses through.

I think Nitrous is a great alternative for people who want a little extra power but don't need it all the time. I'm looking into a nitrous kit for the fun factor plus it's a nice show piece. For $1,500 a kit, it would take many fillups before I'd equal the cost of a turbo. It won't give me 300 WHP, but 270ish is very possible.

To each his own. Best of luck!

Its interesting that the highest horsepower rx8's aren't running the ap... but I am sure that is just coincidence...


Now that is out of the way... the fact of the matter is what is being said as fact is really just opinion. Everyone had great success with the Int-x. Then the new toy came out and everyone hopped on the AP band wagon. The ap has been out for a little while and to me is still earnings its stripes. Whether or not it's better is up to the user. If I were you guys I would let the facts come out and not try to talk a product up like its the end all and be all.

Its interesting that the highest horsepower rx8's aren't running the ap... but I am sure that is just coincidence...

that's not true. There are just as many published dynos of rx-8's running 380 whp with the ap as without. Also there are a few race teams running the AP.

Even if it were true though - I'd like for you to explain to me what makes a non ap unit do better with regards to timing and fuel that the ap cannot do. Or maybe there's some other magic ingredient to it? Tell me more.

Anything that cannot idle properly, or adjust with temp change is a gimped system no matter how you look at it.

I have never had an idle issue. Infact the stock pcm gave me more issues during idle then the Int-x has. I am not trying to argue with you Jason it just gets a little old seeing people constantly bashing stuff that has consistantly worked for the past few years and has been working on some of the most powerfull cars on the boards (using the rene).


The fact is its about tuning... If you don't tune any system correctly you will get detonation plain and simple. I don't want this getting into a ap vs everything else battle.

when the stock pcm was giving you trouble, was it an aftermarket tune or one from mazda? once you switched to Int-x did anything else change or was everything, including the tune settings, the exact same? I'm not discrediting either one (at least not in this paragraph), but there's honestly no way you can link the change in performance in that situation to the change in management systems.

The AP has at least reached a point where it's performance can be backed with data, so at the very least I'd say they are on close to equal grounds, with the AP being the cheaper alternative. So unless there's something I'm not noticing that makes the other options a much better choice, or a better choice at all, then why not get the AP?

installing a Greddy turbo was problem #1. :(

In my opinion...the Flash tuning systems haven't proven themselves over about 320HP. The MAF starts run out of room at 340-350....and until all this is addressed with larger MAF tubes and scaling the higher HP systems will likely run the MAP based ECU's

I think the MAF based flash stuff for a NA car is the best option by far..and for 320 WHP and less FI it should be better as well.....

We will see when the Hymee system and the Flash tuner for the AP comes out what will shake dowm in the tuning department :)

+1

But I am running both the AP and the Interceptor so I got the best of both worlds.

swoop....Its possible i did it i have sheets packed up with a bunch of stuff im moving so meh dont really care to prove it to some internet no body trashtalker....

Thanks to the rest of you. Cars staying turbo although going gt3076 r on a custom manifold with external dump with big injectors, pump, intercepor x, and mazsport coils may be a bit cause im moving and the car isn't my daily anymore

The MAF starts run out of room at 340-350....

The MAF will read out to +360 g/sec.
That's 47 pounds of air, which translates to well over 440 HP at the crank.

I have been driving my STI with the AP installed and tuned for over a year and it's awesome. So easy, so safe, and so reliable. Since I've been out of the 8 for over 2.5 years now, I cannot speak on behalf of the AP on the 8, but had this product been out when I had the greddy turbo on the 8, I definitely would have used it. I know comparing these cars are like apples to oranges more or less, but there are very high hp Subies that are tuned with the AP. Lots of people well into the 400whp and 500whp range that tune with it. Cobb does their hw before releasing a product for sure.
And by the way, MM, that avatar makes me laugh...after I almost puke when I think about the other thing!

Not sure, having no experience with the AP, but have spoken to several STi drivers that are complete Cobb whores and still went MAP once they got in range of 400whp or more. One rationales was:

I'm running a turbo xs utec ems where it is completely map based at anything greater than 25% throttle (user define tps crossover), and maf based below 25% to keep the more streetable. The utec is a bit more advanced than the accessport, and allows for more extreme tuning for some of the heavier modded cars. The accessport is great but you'll discover it has its limits because of the maf.

You're describing the emanage ultimate.

You're describing the emanage ultimate.

That's the STi owner's description, not mine. I think comparing the AP to the Ultimate is misleading.

The apples to apples here is MAF vs. MAP at higher volumes. Clearly, this is one example where a STi owner - and I know first hand this guy can do his own tuning, etc...so he is car literate - has a preference for MAP instead of MAF when his power levels surpassed a certain threshold.

For our purposes, this relates to AP or INT-X and which is going to be better for us past say this 350whp mark that Dannobre has mentioned. I've yet to see anywhere near a 350whp dyno with the AP, but we have seen that and more with the MAP based systems.

That's the STi owner's description, not mine. I think comparing the AP to the Ultimate is misleading.

I wasn't comparing anything to the AP. You were talking about MAF/MAP system. That's what the ultimate does. MAF till the pressure map is activated, then it becomes MAP.

You're taking this guy's comments in italics in the wrong direction.

The transition from MAF to MAP has zero bearing on what option - MAF or MAP - will be the preferable option, or for that matter the viable option, once air volumes exceed X level on the RX-8.

I'm not taking anything in any direction. I made a simple comment on the description of a fuel management system.

Just because you haven't seen a 350 whp dyno with a MAF system doesn't mean it can't happen. We didn't even have a RX-8 renesis dyno above 330 whp till 2008. The AP was only released a few months ago. That means you're giving the int-x a 3 year head start on the AP and complaining that the AP has not yet shown 350.

I can pull up countless threads of high hp cars on iwsti running the AP. When the MAF has it's limits, and one still cannot afford the Hydra standalone, there is a simple fix. A BIG MAF INTAKE! Cobb offers a big maf for the legacy gt that's 70mm, and then cars start hitting the wall around 380-400whp on the stock maf, they throw that bad boy on and problem solved. APS makes a big maf intake as well, and it's a cold air. I'm just saying for the money, ease of use, and reliability, there is no other comparrison. Utec has had problems frying some STI computers. Here are just a few from about 10 seconds of looking around.
All I'm saying is that if other cars can do it on an AP, still pass emissions because there are no CELs, and be as hastle free as stock, why not? Notice just about all these intakes are big mafs. Sounds like a great solution for the Rx8 too!

yeah, you can always increase the maf housing and rescale the maps. Jeff does this for the various setups we use. e.g; GReddy maf housing isn't the same diameter as OEM.

You can also replace the maf sensor itself.

Personally, I'm running an Int-X (bought my turbo kit before the AP was released) but I've been thinking about the AP much like I used to think about Pam Anderson when I was in HS (oh, what I could do with a PA or AP). There are some questions I have about it though and I don't particularly need to swap management at the moment.
1. What fraction of a second does it take air to travel from my MAF to my TB that creates a delay in readings (MAF v. MAP) and how does that compare to the delay I have right now with the routing of the manifold pressure to the Int-X. With a vented to atmosphere BOV, is there a rich condition caused by venting metered air?
2. Assuming the AP is simply a flash of the stock ECU system, would it also inherent the limitations of the stock ECU? The stock ecu is designed to run a renesis engine so it is probably the best equipped to do so. However, it is not equipped with any auxilary controls/inputs that can be customized.
3. There is no tuning software available to the common purchaser today and that's a significant draw back. The stock ECU has a glut of maps and functions so how hard is it to work with? An Int-X is course and simple, but it's fairly easy to adjust.

I might eventually switch to an AP or just run both. I'd like to clear my christmas tree of dashboard lights.

i'd just like to point out that the highest whp rx8 was dynoed at 226whp. and that rx8 had a lot of money spent on it. custom headers and exhausts as well. the next highest whp rx8 is in the 205 range.

you're not going to see 250whp n/a. unless your name is teamrx8 you wont see 220whp n/a either.

I am running both the AP and the Interceptor. I use the AccessPort to increase my oil injection, to turn off CELs, and to increase my idle speed. I use my interceptor to control everything else. I don't have any CELs and my car is running great.

Not sure, having no experience with the AP, but have spoken to several STi drivers that are complete Cobb whores and still went MAP once they got in range of 400whp or more.

The MAF tube on the STi is only 3". 'Nuff said.

Meh, I might disagree on that.
It is a safe generalization, but I have a few 215 HP N/A RX-8s running around out there.

MAP) and how does that compare to the delay I have right now with the routing of the manifold pressure to the Int-X.

In the range of .0003 sec. However, the air itself doesn't have to travel that distance so "slowly". It just bumps the molecules in front of it forward, so the air actually arrives at its destination somewhere over the speed of sound.

2. Assuming the AP is simply a flash of the stock ECU system, would it also inherent the limitations of the stock ECU? The stock ecu is designed to run a renesis engine so it is probably the best equipped to do so. However, it is not equipped with any auxilary controls/inputs that can be customized.

The OE PCM is more powerful than ANY aftermarket EMS out there. What AUX controls do you want? You can use unused AUX items in the OE setup (like the VFAD) to control stuff.

3. There is no tuning software available to the common purchaser today and that's a significant draw back. The stock ECU has a glut of maps and functions so how hard is it to work with? An Int-X is course and simple, but it's fairly easy to adjust.

There are a HUGE number of things to play with. Its a bit like the AEM EMS. THe software not being out yet is probably a good thing, especially fro the FI crowd. There is a steep learning curve.
The Int-X is simple because it is a hammer. A good EMS should be a scalpel. The OE PCM is a laser.

I don't have any experience with the AP, but I do know that my car is quicker to respond to throttle input with the IntX now installed. Not sure how much of that is due to the tune and how much is due to the whole MAP vs MAF thing. I do remember reading in one of Jeff Hartman's books that MAP is generally more responsive than MAF. He didn't give a specific figure, so I don't know by how much. I would imagine it varies by application.

I do remember reading in one of Jeff Hartman's books that MAP is generally more responsive than MAF. He didn't give a specific figure, so I don't know by how much. I would imagine it varies by application.

Exactly the opposite.

And, no, Hartman didn't say anything of the sort.

If you think about how each works for a second, you will realize how absurd that assertion is. In fact, in some applications, a MAP is a better system because a MAF is too sensitive.

Sorry, hadn't checked this thread for a couple days.

Knowing that my memory has known to be wrong more than 1 billon times, I took a look at the book again to see what the heck I was talking about. I believe this is where I got the idea from. The book is "How to Tune and Modify Engine Management Systems" by Jeff Hartman.

On page 22 he says "MAF meters tend to be slow to respond to rapid changes in load (sudden wide-open throttle) and therefore require supplemental means of control to manage engines under rapidly changing conditions".

On the same page he says "Speed-density control systems respond quickly to changes in load".

However, I would imagine if the "supplemental means of control" he refers to are present, then it renders the comparison moot.

Both require a throttle position sensor.
However, he is wrong about the MAF sensors being slow. I'm not sure where that quote is, but I'll take him to task on it when I find it.
MAFs will register if you sneeze on the air filter.

The copyright on the book is 2003. Have there been changes to MAF sensors in general since then?

The MAF quote is from the first sentence of the third full paragraph on the right side of page 22, at least in the version that I have.

Well, obviously, Mr. Hartman was confused.
Look what he wrote on page 40 in the very first paragraph about MAFs.

This is why you must take this stuff with a grain of salt.

True, although he does say the MAF reacts "almost" instantly. Although I would think technically neither one could react truly instantly.

In either case I'm guessing the difference I feel in my car is due more to the tune than the type of sensor.

I haven't seen much difference in terms of reaction time between usage of the int-x vs ap. They both respond appropriately. The only noticeable thing is the poor idle characteristics of the int-x, but I'm not sure if that's a MAP thing or the way the int-x itself operates.

but I'm not sure if that's a MAP thing or the way the int-x itself operates.

Both.
MAF is instant. Air and fuel are not. That is the only delay in a MAF-based system.

I've actually managed to mostly solve (knock on wood) the idle problems I was having. But I've only had it installed for a short time, so I don't know if time will reveal more of them. I do plan on putting the IAT sensor on, so that should help some, I would think. I bought it back before the AP was released, but only got to install it recently.

I do know that Scott said that the idle is easier to control on the AT (because of the constant load, I believe). However, my main idle problem was hot start idle when the car was in park or neutral. That problem was fixed by adjusting the TPS_Cal function.

The car has definitely picked up some power and responsiveness as opposed to stock with the Mazsport base map.

My idle was mostly OK with the int-x, but it had issues when it was hot out and using the mazsport cooling fan mod at the same time. Idle suffered and the car sometimes stalled. Scott was not able to correct it so I ended up inducing a vacuum leak on the top of the intake manifold. This lessened the problem. Eventually I tired of doing that I simply unplugged one of the fuses during summer (when it would have been more useful plugged in). With only one fan on high setting, the car stopped stalling.

Even if your idle seems ok and you don't stall, the idle isn't necessarily great as you tend to end up with an idle in the 11-12 AFR range. Stock setup will idle around 15.

So far no problems with the cooling mod/Intx combo.

I've got a WBO2 on the way (and the temp sensor), so I'll know more about the AFRs in the near future. Thanks for the tip - I'll be sure to check out the idle AFRs.

JFYI the coolint/int-x issue was reported by many members. Not just me. That's how I got the vacuum leak temp fix, from someone else who had the same problem.

Yeah, I remember reading about people having trouble with the IntX and the cooling mod causing idle issues. I was just saying that so far I'm not one of them (knock on wood).

You mention you had the problem when it was hot? I assume you are referring to ambient temps. I lived in FL for a few months many years ago, and your ambient temps are definitely hotter down there than ours are up here. We only get a few days generally of what you guys have all summer long.

Did you have the IAT sensor installed on your IntX? I don't have mine installed yet, but I will be putting one on soon. I'm hoping that helps alleviate some of the temperature related issues some have reported.
