I used to have a 2006 Pontiac GXP which I bought brand new. Since day one it displayed the same issue, and always did until the day I sold it.

I used to have a 2006 Pontiac GXP which I bought brand new. Since day one it displayed the same issue, and always did until the day I sold it.

Sounds to me like you're set up for non-ethanol fuel (14.7 afr) but are running 10% ethanol fuel (14.11 afr)
IMO you should change the AFR from 14.7 (the first box is the only one that counts in...
Yep, the G8 gets LOTS of popping because it (a) drops the timing a LOT and (b) takes a WHILE to get there (to transition) ... i actually changed mine to be much more like the 7.0L Corvette (with...
That definitely will disable CFCO!
Sweet! I'd love to see that stock calibration once they're out! I have a 2009 G8 GXP, same engine, different gearbox (M6).
You're quite welcome.
Well, looking it over briefly ... its not much of a tune. Some things are done right (such as Throttle Opening Rate set to 100%) but ...
- The MAF Calibration / Airflow vs...
Also +1 RE: Stock file. :)
PS: GREAT job ... You guys are the best!
Thank you! It is fascinating to see the cold start low temperature changes they've done for emissions.
(Hope you are well!)
He's right - I was sleepy last night and saw that "O2 sensors turned off" and assumed it was the front ones since you said it was rich.
...
Still as Mowton and I pointed out ... There is indeed...
From what I see in the [Engine Diag] section, the car has NO O2 sensors working. :-( ... so, yes... rich. Always.
Bad tune in a lot of ways, but that is the absolute killer. :(
Yep, it was indeed the 1.8L 4cyl. Shame RE: the E83.
Thanks for the quick response guys. (I was really dumbfounded for a while there!)
I'll keep my eyes peeled, maybe you will add support one...
Agree 100% with IDriveAG8GT !!!
Also, if you have E10 in your area, set your AFR to match.
Fuel -> General -> Stoich AFR -> 14.222656 across the board.
(about E08, close average for areas...
I tried to read a 2012 Chevy Sonic (non turbo) today, and no matter what I did, the software was never able to locate the PCM.
I updated to the latest beta a few days ago, but still nothing. Any...
Here are two more that come from the 2010 Camaro 6.2L V8 M6. Also stock values.
File 02a has richer fuel values where I suspect your stumble is - I know its in the "Park/Neutral" values, but I...
It is hard to say without a log, it would have been nice if that cold start you did log would have had the stumble ... but ...
What you describe sounds to me like lean stumble. Two possibilities:...
Sick_WS6, It could very well be, depending on what mods you have....but...
...I would think that in those 60 seconds you'd still be in cold loop. I should have said above "That table is used for...
Shame just setting it to manual didnt solve it. I can't advise you on the 12v at the cpp pin. I don't have enough experience with PCMs to do so ... though if it were my car, I think that is exactly...
Sure. Its easier to understand on the first Gen4 calibrations, such as the 2005 GTO. Instead of a table, it had a single crossover value, a max temperature, and a timer.
Whenever you started the...
Shorties are no problem. Unmetered air tho - that creates all sorts of weird issues with fuel trims! Sounds like you are on the right track. Taking care of that most probably will solve your...
The Auto / Manual switch I described is not too old and many older betas did not have it.
Look for Trans -> Auto Shift Properties -> General -> ECM Trans Type. Its a switch that lets you set an...
That table is only used to offset O2 crossovers for (about) the first 30 to 90 (or so) seconds that the engine is running. After that, it is ignored by the ECM.
That makes three of us - I too am curious.
Like MikeOD said - Adjust the Stoich AFR, dont chase it with PE ...
Under Fuel/General/Stoich AFR, I use 14.222656 across the board for E10 (its about E08, very accurate for South Florida)
You...
Write Bill, and ask to download the latest beta. You could then try under "Trans" to set the "General / ECM Trans Type" to "Manual" and see if DFCO works then.
That might satisfy the ECM.
Wow. Those ARE some crazy fuel trims! The O2 crossovers are so JUMPY!
I owned a 2006 GTO for a number of years (have a 2009 G8 GXP now) and did countless logs on it - I just looked at one and it...
