I posted this before, but here it is again.

wow AFRs in the 13s .......

That's what it is supposed to be.......while N/A.

That's what it is supposed to be.......while N/A.

my point exactly - wouldn't 13s be a recipe for KABOOM !

Exactly. I was just backing you up, Bro.:lol:

Under load, it would be a bit leeeean.

Not to mention produce way less power, even if it didn't detonate.
12.3:1 or so is the leanest point for power on the Renesis.
11.5:1 is as high as I would go with any serious boost.
I stay below 11.1:1.

BTW - how much boost is represented in that plot? ~260 HP and ~180 tq would equal about 4 PSI on my turbo.

~260 HP and ~180 tq would equal about 4 PSI on my turbo.

you are such a s**t stirrer MM :lol:

Can we have a dyno sheet on this please?
No, your rear is not a dyno! :banghead:

:lol2: :lol2:

butt dynos not withstanding :rollingla

correct me if im wrong fellas....

how can you compare lbs of boost on an SC and a Turbo?

i know they both produce boost....but where is the equivalency?

It's a rough comparison, one that is dependent of exactly where it is being measured, but when speaking generally the needed A/F ratios are pretty consistent. The real deal is looking at mass air flow.

BTW - how much boost is represented in that plot? ~260 HP and ~180 tq would equal about 4 PSI on my turbo.

He's talking about backpressure in the exhaust.:lol2:

Thats s the a/f ratio"s!!!!!
Holey crap. I hope everyone is running wide bands! Is that with the flash?
oscd

there is going to be a run on water meth injection systems
oscd

I have a wideband and under WOT, I've never seen it above 12. I don't know why it was so lean on the dyno. I'm figuring because it was reading post cat

butt dynos not withstanding :rollingla

Are you the only one that realized in this particular instance, I was talking about the carpet? This was in response to you and Brettus talking about it. That's why it was right under your post and not under Jeff's request for a dyno from somebody with a Pettit SC. Maybe, it's late, but I don't think everyone got that???????

Well I'm starting the installation this morning. Hoping to have everything complete withing the next two weeks. I'll take pictures of the whole process.

Welcome to our group..................The best on your install

That's what it is supposed to be.......while N/A.

I saw as low as upper 10's when NA while WOT.

Is there a way to estimate the amount of air this SC pushes at 7-8 psi, and calculate based from the increased air, what the AFR would be if the PCM wasn't adding additional fuel?

If I can of any help with the install--just shout out.
Welcome--its a great kit but as with all major mods you can do a little tweaking to make it better.

Well I spent the better part of the weekend working on the install and made pretty good progress. We did run into some issues with what was supplied but I hopefully can have everything resolved Monday. I'll post some pics on Monday. I'll also have a few questions once I can find my notes.

great!!

post questions...we will definitely try to assist...

PS - New purchase soon. I need new wheels so I'm thinking of the Enkei RPF1s 18x9.5. What do ya' think??? Miss ya'll...I'm up here in the Poconos. It's cold, snowy (but the 8 is friggin' awesome in the snow with these tires) and I miss Southern California so much...

I have a quick question. Can anybody help me pull the pin out of the throttle body connector? We have to reroute 1 wire through the main bundle and can't get it out of the connector.

thanks

The throttle body connector has a plate in the pin side that comes out--if i remember correctly it is white. Once that plate is removed then the pins release in the usual way. Learn a lot doing this dont ya?
olddragger

I think he is talking about removing the wire from the harness, not the TB plug, itself.

I popped the white "plate" out and the pins still didn't want to release. The white piece didn't come completely off just released. One wire from the Throttle Body connector needs to be routed around to allow me to keep all of them bundled.

More than I care for. Keep running into issues with missing components and other things that slow everything down.

yup..... Ray, care to comment

The pins are inserted into the connector from the harness side with a one-way locking tab. A small, toothpick-like, tool is used to release the tab so the wire can be pulled back out of the connector. The Weatherpak o-ring that surrounds the wire must be pulled back, first. A little silicone spray may help to slide the o-ring back a few inches and you can start feeling around for the lock-tab. Hard to see, so it is a "feel" thing.

I used a very small srewdriver (made for tightening eyeglasses) that worked great for this--and yep you are correct it is a feel thing.
Dog--what parts are missing? I know I was VERY careful in doing the harness etc rerouting and in trying to get the vacuum hoses routed correctly.
A couple of hints
1- reroute the oil filter--you will be glad you did. You dont HAVE too, but it is better.
2- make sure you have a screen on the maf pipe---it needs a smooth flow now -more than ever.
3- make sure your fuel system is good---no pressure issues. our fuel pump has been known to deteriorate.
4- Detoniation in the rotary sounds like a vibration/aluminum can crushing--it is not like a recip!
5- pull the room fuse every day or after a LONG trip.
6- watch the a/f's
7 --make sure the alternator wire is secured well away from the pulley's.
8- mount the coils as LOW as possible to give as much clearance as you can to the maf pipe.
9- I was able to redo the hose configuation of the a/w intercoolers to make room for the RB cold air scoop thing--if you have one--look at it and do it. the engine is now reading the iat's from the maf and cool air to it is good.
Holler out with any questions you may have.

2- make sure you have a screen on the maf pipe---it needs a smooth flow now -more than ever.

What are you using for a screen?

What are you using for a screen?

I use a piece of standard window screen. :eyetwitch

I was thinking of using a nylon window screen just in case it were to get sucked into the turbo. Plus it should be easier to work with. That looks nice though! Thats not the new Pettit MAF tube is it? If not, are you supposed to be getting the new one?

The metal screen sits very tight and does not flex like a nylon one.

It is a loaner from Cam. I talked to Cam last week and I'm going to stop over his shop in April and I'll swap it for the new one. :eyetwitch

ive got a metal screen like juans...got the new maf tube...havent had time to swap it out...

Thanks. I have seen it before. It looks very nice.

5- pull the room fuse every day or after a LONG trip.


Huh? Why would you need to do that?:eyetwitch

I thought it but didn't ask it... My guess would be because the tune only addresses open loop and the tuning software has no means to change the transition between open and closed loop.

Na, dont have to pull the fuse everyday. The ECU tunes to optimum in a few drive cycles, holds ok for a few days but trims after few more days. The new flash has rectified that issue. Crawl, step, run. Id say it takes from 250 to 500 miles to enter the to lean zone, if it does, wich most of the 04s wont trim into the zone.

Also, dont hold me to if its the rite size but I think it is, you have a screen in your stock airbox with a steel liner, see how it fits in the housing to filter, im pretty sure its the exact size and cant get sucked in.

I thought it but didn't ask it... My guess would be because the tune only addresses open loop and the tuning software has no means to change the transition between open and closed loop.

Its a flash, right? You can address open and closed loop with a flash. Just change the lambda targets and you are done.

Huh? LTFT/STFT are designed to compensate for variations in the injector tolerances, not change the tune.
If the trims are changing the target values, then you need to go in and change the target values.
There is no reason for the fuel trims to change the base tune unless it was wrong to begin with.

Hehe, I new id see ya, I still have more miles on one motor biatch, enough said.

This is easy to explain when you consider that these people have been fiddling with the primary means the PCM uses to determine fuelling. The MAF. If the MAF characteristics are modified, and the MAF calibration is subsequently not correct to reality, then the LTFT's will of course change in accordance with the "error".

In this case youre last sentence is the key. The reason the base tune is wrong is due to the MAF calibration not matching reality. Once enough iterations of fixing the calibration in the flash have been done, and the numbers are right, then there is no need to worry about LTFT's and pulling the fuse. It will soon compensate for injector tolerances over time, as what you would want it to do.

Cheers,
Hymee.

No surprise there, they are Pettit Racing after all. I think it's just easy to take a cheap shot and poke fun at Jeff about his multiple engine failures because the circumstances of those failures weren't totally about pushing them to their limits. That doesn't make it any less of a cheap shot though, and I know I for one am guilty of taking them, but of course, he is too.

I may take you up on that, Charles.

I agree Bas. However, Jeff has been treating people quite well lately and Moon's comment was rather non-sequitur given our line of discussion. Besides, I find it far fairer to just man-up and call Jeff an asshole, straight up. I have done it plenty of times on this forum and I am sure he has called me a fool somewhere/sometime, as well. How is it that he and I are still friends despite our differences of opinion on some matters?:)

BTW, Jeff may not have intentionally discovered certain limits with his accidental dalliances but his sharing of the stories with us certainly provided illumination. Given that some around here think there are "secrets" in the world of performance engines/tuning I am thankful for those who choose to share.

Whenever you're ready I'll take the order!:lol:

Well, blasting up a mountain at WOT and full boost in the summer chasing (and passing) a Mustang is about a legit as it gets.
Unless you've driven that part of the run from Tortilla Flat to Roosevelt Lake, its hard to get a picture of just how extreme it actually is.

You're welcome, Asshole.:lol2: (I have stolen that from Denis Leary in "Rescue Me" as that is one of my favorite shows) When I call you that it has no connection to the facts, JUST your demeanor. I am not trying to change minds around here just allow people insight of my own opinions and let them decide for themselves whose views they are most comfortable with.

Get a jack ass of a response like this? If this is the kind of people who work for Pettit you guys really need to clean house. Regardless of what Jeff has done in the past a comment like this is not warranted especially since all he was doing was trying to help. Given you guys are vendor and this Moon character represents Pettit with his GED-less type posts it doesn't make you guys look respectable at all.


Hehe, I new id see ya, I still have more miles on one motor biatch, enough said.

Hit, we didn't spend a whole lot of time on the issue because this has all been discussed several times in the past and it needs no further contemplation. To continue runs the risk of veering this thread off-topic and into personal bashing.

Moon isn't a representative of Pettit.
Because Cam doesn't venture out into this medium, he is blissfully unaware of Moon's antics.
I don't think Cam has too much to worry about since most of his bread and butter does not come from internet sales.

I used to think Moon was just, for lack of a better word, "impaired", but I've come to realize he is actually mentally ill.
I really hope the best for him, but stories like his seldom end well.

Is there an updated flash fron Janurary? Cam told me to pull my fuse often--I have an o4. He even put a pig tail on my room fuse to help with pulling it. Its no big deal. By daily I guess I meant I just have developed the habit of doing it every day. A fellow member even came up with the idea of putting a switch on the room fuse to make it even easier. Better safe than sorry?
I have modified the rb maf pipe/horn, filter(not the box) and CAI collector to fit. I use screen just slipped over the end. One hint --- dont tighten the intake hose to tight as you start to warp the screen/alignment of it all.
olddragger

Annnnnnnny way . Is a flash going to work as well for a Turbo as it does for a SC ?
My feeling is it wont because boost varies so much with a turbo whereas a SC is very predictable - any thoughts .....

Its all the same. Air is air.
Flashes (like the OE programming) utilize load-based tables. They don't care where the load came from.

Boost varies with a turbo exactly as much as you use the gas pedal. Its no different than N/A.
Its the S/C that has a weird air-mass delta since its pumping volume doesn't respond to throttle input like it does in the N/A application.

Cam told me to pull my fuse often

That is such an outrageous requirement that I don't even know how to address it. :icon_no2:

No, Zen is absolutely right.
I have to apologize to everyone on the forum - especially those that wasted even the rarest moment reading the drivel and utter nonsense that I foist upon the good people here.
I just get so jealous of the insight and elucidation that the true leaders of this forum bring - true innovators and explorers like Bastage, Moon and Zen - that I can't help but try to aspire to their level.
Their brilliance far outshines anything that I could possibly contribute.
Their pioneering work in engine management, forced induction design and engineering and their constant sacrifice to bring knowledge to the forum - often at great personal expense - know no comparison. Certainly not from my feeble attempts.
Moreover, their mastery of dialog and their beautiful use of language and syntax brings such depth to the discourse, that I find myself hanging on their every word.
No, I apologize - deeply and truly - to each and every one of the members of the RX-8 forum for having plied my sad subterfuge upon them for all these years.

Asswipe.

They should make this a reality show on comedy central.

How the world functions is truly a miracle. Not just here, but it is amazing to me the energy and time spent on non productive matters.
What is surprising is I never really understood how much Jeff and Moon like each other until now. Can anyone else see that?
Pulling the room fuse is no big deal--hell we have been doing that since the CZ days. Remember NO ONE YET has an independently owner tunable pcm process. This is just growing pains. Not the best--agreed. But the best is not yet available. Hopefully soon. Yall stop making such a big damn deal about it.

I am the proud owner of one of the originally released Pettit super charges and would like to hear from all whom have also purchased one. It would be nice if you also posted if you self installed, Pettit shop install or other third party install.

I thought this was the idea of this thread. Not for all the stupid bullshit going on.

Jeff, you are crazy!! HAHAH :rollingla :rollingla I got tears coming from my eyes, can't stop laughing..

Wanted to thank everyone for there help so far with the installation. Have one more question concerning the gauges. Where have you guys/gals hooked up your Boost?

We are currently starting to work on gauge installation and have come accross a few more questions. We are trying to install Autometer Sport Comp Boost, Wideband A/F and Water temp gauges.

1) What is easiest way to install a wideband A/F gauge?
2) Can it be connected to the stock O2 sensor port?
3) If so will it throw a CEL?
4) Where did people drill through on the firewall for the gauges?

1-2-3) Weld your own O2 bung for the AFR gauge; in FRONT of the Cat. Cost $30 or less to get done at an exhaust shop. You need to leave the OEM one's in place.

4) I went through the passenger side behind the washer reservior.

BTW - Be sure to wire to a constant power source; one that does not turn off when the car turns on. The boost gauge needs to calibrate; and if it calibrates off of the running engine it will always read high.

Thanks. We were hoping that there was an adapter that would allow us to tap inot the existing sensor.

Not really; but it is cheap and easy to weld in your own.

I took my cat off (5-6 bolts) and walked into an exhaust shop - 25 minutes later walked out with my O2 bung welded on; cost $30. I would have done it myself; but our tools are still on a boat from the Middle East.

Is it possible to remove the stock sensor from in front of the cat, then splice the stock wires from the ecu into the bosch sensor and still have everything work properly??

No. You can't do that, as an O2 Sensor needs its own controller circuitry. You don't need to install another sensor though. The data is freely available from the cars on-board diagnostics. Just get a scan tool (you know what I mean :) ) to watch in real time, or a data logger like EFIDudes to use for analysis.

Hymee.

Did you drill the hole in the tube before the CAT?

Yes, BEFORE is key...

What if you have a straight pipe? Where would be the best place to weld the bung?

mine is up front close to the down pipe...

From Autometer:
"The oxygen sensor should be installed as close to the cylinder head as is reasonably
possible so that the sensor reaches operating temperature quickly. If
long tube headers are used, the oxygen sensor should be installed in
the collector. If cast iron manifold(s) or shorty headers are used, install
the sensor in the pipe just below the manifold. In multi-bank applications
mounting in the left or right side is acceptable. Turbocharged applications
should have sensor installed 4-5" after turbo on the down pipe."

The problem with installing an O2 sensor close to the exhaust ports is that it may burn up.

For us; I think where the cat/midpipe meets the downpipe is the best spot.

My pyrometer is on the downpipe and it gets 1200F pretty quick.

I put mine on the catpipe between the converter and the flange to the downpipe.

I was wondering if anyone had any pictures of the Vacuum chamber installation. We are having some trouble figuring out is needed per the directions. I think the part in the installation instructions isn't valid anymore per Pettit. So if anybody has any insight on installing it it would be much appreciated. Also had a question on the oil used in the Supercharger. Does it use normal 20W50 oil or does it need Compressor oil? If so where can you get compressor oil? I looked at a couple of Auto part stores and couldn't find any.

hey Dog
im using Mobile 1 per cam...i think its 20-50...i'll have to check...

i can post up some pics if that helps...just get me in the right area...

thats where mine is ...

I have my O2 sensor installed in the catback pipe. The TurboXS exhaust has an O2 Bung already welded in that pipe. I ran the controller wires up through the gas tank on the passenger side and under the center console to the ashtray area.

thats pretty far back....are you running a cat?
if so, would that change your readings?

No Cat. The wideband doesn't have anything to do with my tuning so it really just runs the AFR gauge.

No Cat. The wideband doesn't have anything to do with my tuning so it really just runs the AFR gauge.

i understand that....
my question is....do you get different readings if its in the back...as opposed to up front..
ie would your AFRs be different...if so, would the front readings be more exact....

I'm not sure because this is the first time my wideband has been installed in this location. However, the readings should not be any different. There might be a slight lag time involved but thats about it.

Also had a question on the oil used in the Supercharger. Does it use normal 20W50 oil or does it need Compressor oil?

Regular Castrol 20W50 for the first 500 miles (break-in) then change to Royal Purple 50W and enjoy it. It will cut down the SC clattering and winding sound significantly after you change it to Royal Purple strait 50W engine oil.

Also, send me a PM with your email and I will email you back enough pictures of my SC to fill your computer hard drive. :eyetwitch

I just received four MSDs 8247 LS2 Multi-Spark Blaster Coils that I purchased on eBay for $245. So far, I plugged one MSD coil to the leading (L1) side by individually connecting each wire to the four MSD coil pins.

The car stated right up and with an inductive timing light I check the spark output. I revved the engine up to 8k rpm several times while checking the timing light for spark output and to make sure that the spark duration/ratio was constant (sorry but I don’t have an oscilloscope).

So far no issues whatsoever.

I'm waiting for four D581 plug connectors to arrive so I can fabricate plugs for MSDs and splice into the OEM coil wires. Once installed I’ll take the car for a spin and will update the thread with pictures. I hope to have everything installed by the end of the week pending arrival of the D581 plug connectors.

I'm hoping to have the D581 connectors by the end of the week because I'm doing an AutoX next Sunday and would like to put the coils to the test. Also, the AutoX event is an hour from my place and I will be driving at interstate speed 70+ for at least 45 minutes each way. I think that will definitely test and prove that the coils work...or not. :eyetwitch

rp is indeed purple, but it doesn't stay that way for long in the engine. I donno what would happen in the blower.

Hey guys. I got my new MAF housing from Pettit. They sent the housing itself and the filter that goes with it. I don't know if i'm missing something, but i've been trying for the past hour to get the original silicon coupling that attaches to the throttle body to slip over the new housing. Is this what i'm supposed to be doing, or am I supposed to use a different part??

What do you mean? You mean MAF numbers?
To go to a flash, you should remove the idle bleed hose so that everything is going through the TB.
The MAF tube that Pettit is shipping is a complete piece of junk.
Besides the fact that it is 7% over-size, the taper is too close to the MAF and the inlet, being so soon after the filter, really screws up the flow.
That said, recalibrating the MAF signal to the PCM was a task, but I managed it. The idle ranges (flow under ~8 g/sec max) needed their own, different slope from most of the rest of the response curve.
Basically, what is normally a nice, smooth arc turns into a bit of a hula dance.
But it works.

Only when it is WOT. After that, it will only flow #^$/TA.

To be pedantic:

We measured 3.405" diameter on the MAF housing I've got. We averaged 3 measurements with a caliper I had in my garage thats accurate to the mil (milli-inch). MM said the stock MAF tube is 3.375 (3 3/8 "). The areas of both work out as such:

stock 3.375" diameter -- A = pi * r^2 -- 8.94618 in^2
my MAF 3.405" diameter -- 9.10593 in^2

percent accurate against stock: (9.10593 - 8.94618) / 8.94618:
1.78%

Sorry Jeff if I misinformed you about the 7%-- Indeed I was the one with the calculater that night so it was probably my error.

Also, during my install at 7stock, Cam/Moon said my housing was a prototype that they had manually machined. I don't think everybody here has my MAF housing exactly, but I think 1.78% will easily auto-correct with STFT/LTFT?

Indeed there is something very strange about the MAF flow at idle, but I watched as Jeff eventually got it tuned perfect -- 1100-1200 RPM rock-solid idle. The test drive showed none of the quirks of the Int-X loaner I have: inconsistant idle, APV valve "clicking" on/off at idle, and the non-linear surge of torque around 3-4k at partial throttle. It would seem as if the Cobb tools allowed Jeff to tune for the Pettit S/C in a single evening which IMHO is very impressive and a testament to both Jeff and Cobb!

The AP unit itself is very cool with its LCD screen -- I especially liked the realtime digital gauge modes (AFR/IAT/ECT/STFT/MAF readings)

Nah - he is referring to my comment on getting numbers on the how much the throttle body can flow - as it is a restriction in the intake before the MAF is one.

Cheers,
Hymee.

Ahh. That makes sense.
However, the engine will flow an awful lot of air before the TB becomes a real restriction as it stands.
The DBW system is limited to a duty cycle considerably less than 100%. I'd be interested in seeing what the actual opening angle is at max DC.
I suppose I could just hook one up out of the air loop and look at it whilst someone stood on the pedal, but that would be way too easy.

Your trying to say the DBW is incapable of holding the throttle blade at 90 degrees? (hehehe - this time degrees IS the unit :))

I should have video'ed it when I was experimenting with the DBW a few weeks back.

Cheers,

Can someone with an aftermarket O2 sensor log both the aftermarket and the factory O2 readings at the same time for a comparison? It might be helpful for those thinking of doing an aftermarket installation to see how the two stack up.

No, it might be capable of it, but the maximum duty cycle commanded by the PCM is considerably less than 100%.
That doesn't mean that 100% = 90°, though.

Already done.
They are pretty spot on from 12:1 up to 19:1. At either end, the OE sensor wanders out to .2 or so max before it taps out at 11:1 and 20:1.

Thanks for the clear up Hymee and thanks Jeff for the info. i was thinking just that.
Just for info--i dont have an idle air bleed any longer--everything is through the maf.:) I have the pettit flash and that has the their maf pipe calibration along with it(duh:)).
I was wondering about the short distance from the intake side to the maf and air distortion. Cam advised NOT to run a screen. i am thinking about using the racing beat filter with their horn mated onto the Pettit pipe, but i want to be careful about deviating from the way the tune is set. In your opinion would that be of some help?
thanks again and good work guys.
olddragger

Just for info--i dont have an idle air bleed any longer--everything is through the maf.:)

Is there still a hose that connects to the "back" of the MAF tube that runs directly to the plenum of the blower?
If so, you still have an idle bleed. It need to go. Everything needs to go through the throttle body.

Jeff,
Thank you for your opinion. Now-

Opinions are nice, but can someone log some data and post it so that others can form their own opion as to how close an aftermarket sensor is to the stock one?

I don't have any documented evidence, I should be able to find some as I have plenty of Motec logging from Wildcards blown RX-8. But I do remember "Grandad" telling me when I did the very first prototype of a scan tool that they were that close it didn't matter. He had a Motec Lambda sendor and controller in my car, and I had the prototype software running, and we also had the old "Ric Shaw" piggy back plugged in as we took a trip the the MazFix dyno. And there we stuck the dyno dynamics lamba sensor up the other tail pipe. So we had 3 going at the time. Kicking myself now for now "recording" it for prosperity. That was way back in very early 2004.

But yes, some empirical results would be great to see.

Cheers,
Hymee.

Jeff--no such hose now. The only thing coming out of the maf pipe is the vacumm for the omp and jet air. The hose I believe you are referring too is now directly and only attached to the purge valve. Not much action there.
On the Pettit maf pipe--, the latest pipe from them looks pretty good to me. Maf mount is tight and it is smaller than RB's pipe and most importantly that is the pipe that the flash is tuned with. I agree. I also would like to have a longer course of air before the maf picks it up but we are spaced challaged. Some data logging would still be good considering car to car differences also. Within the month I hope to get a good collection of data with the logger.
olddragger

Since the purpose of equalizing screens is to replicate a longer MAF tube, I wonder why Cam noted to not use a screen? Especially since the MAF sensors are already hyper-sensitive.....:dunno:

What do you guys think about putting the stock screen in between the MAF and air filter?

Jeff,
Thank you for your opinion. Now-

Opinions are nice, but can someone log some data and post it so that others can form their own opion as to how close an aftermarket sensor is to the stock one?

No opinion. I have hours of logged data.
The relationship I noted is how it is on all of the cars I've logged.
Do it yourself.

I still don't understand where you come off thinking we need to do your homework.

Do not need to. I know they are the same. That is not the point.

No matter how smart I may or may not think I am, I do not expect others to take my opinion as fact just because I post a lot, run my mouth and say "it is so". I try to provide data so others can form their own opinion. I've also been around long enough to have been wrong on many an occasion so I know I do not know everything.

For instance, if I were to say that I did such and such to a turbo installation and got so and so results, I'd post the data and say "I think this is what is going on, anyone have a different opinion?". I'd probably post the file too so others could give it a try but I think I know how you feel about that.

Hymee,
I know you are buried busy. If you get a free minute to post the data I think it would be helpful. I trust the factory sensor but there may be others out there that want to see some proof before they trust it to do their own tuning.
Thanks, Lola

I've got heaps of MoTeC logging. I've got lots of CSV logs of sCANalyser Live. Some of them might even be from Wildcard's car when we had the MoTeC bung in it as well. But I think I would have a very difficult time finding it all, and then correlating it. It would be quicker for me to do some fresh logging with what I have, and borrow a MoTeC from Grandad. But I don't want to put a bung in my pipe at the moment, so it will have to be up the tail pipe. And then someone will argue with that...

What I need to do is look at the "calibration" curve with sCANalyser Live V2, cause I can log the Lambda as well as the volts (current?) as reported to the PCM.

Hymee.

I'm waiting :scratchhe

im thinking.....and by all means correct me if im wrong..... :lol:
the AEM CAI is much longer and actually goes into the nose...
therefore, would the air thats going in be much more stable as it reaches the MAF sensor?

:dunno:

The longer the tube before and AFTER the MAF, the better.

Jeff, did you have to put some type of screen in front of the pettit kit MAF in order to tune it properly with the AP??

I'm not sure if the vehicle that I just worked with had a screen or not.
Since the idle is so high on the Pettit application, the accuracy of the low-end flow isn't as important.
I'd suggest it, but getting the MAF tube out to a proper length is going to be more important.

Jeff, were you able to address the high idle?

My understanding Lola is since the s.c places a load on the engine from idle upward--it requires a faster idle than oem. personnally i have always preferred an idle of around 1 k on this engine. it seems happier.
olddragger

I must be lucky. My idle has always been stable and "rock solid" at 1100 rpm after the SC install, everytime, even after I reset the PCM (pull the room fuse). And I'm running a screen.

Zen, the 1,100 rpm idle speed has always been smooth. The idea was whether ot not 1,100 was a desirable idle speed or not.

As the S/C places more load on the engine, as does an A/C compressor or alternator, the speed of idle need not change. The trick is to automatically get more thottle opening to conteract the load, but not exceed it, so the target RPM remains the same.

Cheers,
Hymee.

MM was thinking, last I knew, that the S/C may have been wreaking havoc on the MAF sensor as a result of a few issues. Any ideas, Hymee?

MM was thinking, last I knew, that the S/C may have been wreaking havoc on the MAF sensor as a result of a few issues. Any ideas, Hymee?

In theory, at idle the S/C isn't "there" as the bypass valve is open. In practice the bypass is actually open. What this means is that the S/C is no putting any boost into the intake, or drawing in any more are than what the engine wants. So in this repsect, theory matches practice.

I assume what your getting at is the concept of "reversion" (i.e. the S/C creating pulses back up the MAF tube), which needs more study I guess, rather than postulation.

That said, the engine still has a net postive flow of air that is all being measured by the MAF...

Cheers,
Hymee.

Yep, the reversion-pulse theory.

You go, guys. I can't wait until you work the bugs out of this piece of crap:evil_laug

I'm not sure if the vehicle that I just worked with had a screen or not.
Since the idle is so high on the Pettit application, the accuracy of the low-end flow isn't as important.
I'd suggest it, but getting the MAF tube out to a proper length is going to be more important.

Could you find out, because i'm thinking it wouldn't be hard at all to glue the stock screen to the front of the new MAF housing?

Yeah, it has to be kept up to 1100 because of the way the kit is designed.
If it had been done right, there wouldn't be a load at idle.
I can set the idle anywhere I want, but it seeks pretty heavily at anything under 1k.
The BPV flutters, too, which makes it even more difficult.
A clutch (like the OEMs) would have fixed this.

A couple of points (before people get their panties in a wad):

The cause of the bad idle is not totally clear to me, but it appears to be a combination of "chopping" from the blower, odd spring tension on the BPV, bad MAF housing design and load.
That said, at 1100 RPM, it is quite nice.
I don't know that I hate it. lol.
Honestly, the twin-screw makes some really musical noises and the power delivery is more than satisfactory.
From the beginning, my assault on the Pettit is not because it is an SC but because the engineering of the kit was so lax.
Fortunately, the issues are being met one by one and it will ultimately be an excellent system.
Its just too bad that the owners need to bear the brunt of this re-engineering effort.

sounds like the first run's of the greddy kit. Just my thoughts haha.

first run? greddy never fixed anything of substance even today. That's why we replace the fuel management, and better yet, replace the turbo. Then it's a damn fine kit.

Yes, Varney. There is the engineering and then there is the politics. Rarely do they have much to do with one another.

Think - Army Corps of Engineering.
Then think - New Orleans.
Then think - Katrina.

Politics and engineering mixed into the finest broth!

OK... I'll start by saying...

Nah nevermind, not worth it.

Anyone now who won the BP car, maybe a friend of a friend. Who ever did is one lucky basterd.

I got inspired and started playing with the Electronic Throttle Control stuff a bit. I had the idle down to 950 and the ETC caught the rapid throttle off about 85% of the time after a hard pull but it would still stall from time to time.
I know, I know…. That is not good enough and I agree but it was a lot better. You can also let the clutch out now without touching the gas and it will drive away (like a proper ETC car should).
I'll keep at it when I find spare time and maybe I will get lucky.

Yeah, fuck me, what a piece of shit this Pettit kit is, especially after that Moon guy came and gave me that crappy install - I should have listened to all the advice I got here. I've been pissed about the idle since day one. I'm actually thinking about an IntX and Greddy, or maybe something reliable like a Turbinator. Anything to get me away from the driveablility and 20 mpg, ANYTHING. Dear God, save me from my supercharger!

Not.:lol2:

What are you trying to say, Zen? I can't tell if you really like your S/C or not.

I sent them an email a month or two ago asking the question, and they have not responded. I'm guessing their using the car as a promotional tool all over the country... too bad it's an auto

Yeh, Cam noticed we forgot to do the bypass mod, ill do it in the morning.

What an auto hating Bastage you are, dam you to hell.

What are you trying to say, Zen? I can't tell if you really like your S/C or not.

Like I told Cam: this kit has been so damned good right from the start I can't believe it. It is without a doubt the most satisfying modification I have ever made to any vehicle. By the time you guys get all these terrible kinks worked out, I'm gonna have to move my seat back even farther; I'll have so much wood that Shinka will be using my picture for her avatar :)

And just in case you haven't read well 'tween the lines, Moon fucking rocks.

got my efi dude today....gonna do some loggin tomorrow if the weather cooperates...
:D:

Nice tool that. Essentially a mini MoTeC plus the Interprerter software. I don't think you can get a MoTeC with Lambda logging enabled for under a couple grand. At least you get a complete ECU, but we alread got a great one courtesy of Mazda.

Cheers,

What data are you looking for?

wanted to check the AFRs and the timing...for starters

i did a couple of runs today....got 2 good pulls in ..just over 8k....traffic was a little tight...

the software is really cool...does lots of neat stuff .....

on the first pull...2nd at 8066 the AFR was 11.51
on the second pull...2nd a 8002 the AFR was 12.49

these #s are coming from the first pettit flash

Kind of lean - did you hold the RPM or were you at WOT gunning it.

Did the AFR come off your Cobalt or the stock Wideband?

Both have latency; so a quick run might screw with the info.

readings came from the efi dude data logger...
plugged it into the opd port...

i cant really get an accurate read on the cobalt while im driving...there's too much change...and i'd rather keep my eyes on the road...

basically it was a pull in 2nd from a stop sign to the next...i ran out of room to take it further...

these were my first runs with the DUDE...next run, i will spend some time on the highway etc...to get a better over all pic

Yeah, try to load it up and hold it for a second or two - the tail end of that will be more accurate.

If it is still reading high 12's at 8000 RPM, then you might want to address it...

i will be getting the updated flash soon...
ive emailed my data to the appropriate authorities... :lol2:
for their perusal...

HAHA, sounds good to me!!!!

BTW - your autometer can Datalog as well; with both, you can cross compare.

is there software im not aware of for the autometer?

There are options to send the AFR info to an external logger.

thanks Kane

im thinking i'll stick with the efi Dude....
its so user friendly, even an ole lady can use it..

:D:

We are alomst done and as usually with each step I have a few more questions.

1) The picture below shows a wire clip that I can't seem to find what it attaches to. Can someone please point me in the right direction.

2) How long does it take for I/C pump to start cycling coolant? It doesn't seem to be doing anything, When we first hooked it up it wasn't even pumping just overheating. Then after disassembling it we got it to start to pump. But it isn't cycling the coolant back around.

3) What are good AFR's going to be when running?

That looks like a plug/socket that isn't connected??

Cheers,
Hymee.

That looks like the VFAD plug. Is it attached to the MAF wire? If so, its no longer needed.

A/C clutch compressor connector? I/C pump needs to be primed, too.

I've got that one covered. It also has a green plug.

But thanks

Yeah that is what happens when it has been 20 straight hours in the garage and your fried.

A/C clutch compressor connector? I/C pump needs to be primed, too.


Thought that might be the case with the pump. Figred I would check first.

Will check the A/C it is right next to it so makes sense.

I do have one more question regarding the VDI connection from the Vacuum box. When I spoke to CAM last week he said to pull the hose that connects between the Vacuum box and the VDI. I just wanted to make sure which one he was talking about and find out what VDI stands for.
