It did cause the GTO to run poorly. Turns out I didn't set the maf frequency values to allow for speed density. once I did so there was an improvement. I reverted the VE table back to stock and now...
That may be a factor. how can I rescale the MAP sensor. I read somewhere its about messing with the offset but how?
The tune has been scaled for larger injectors. I input my data for my fuel injector clinic 1000cc injectors. I scaled engine displacement and MAP/MAF readings according to my calculated scale...
supercharged gto with NW102mm throttle body. car is tuned to stock only thing I have done is literally double the VE table values and MAF low frequency. everything else is like stock in tune file.

It's PCM regulated.
Recently I discovered that a lot of Gen4 vehicles have a PCM regulated alternator. Alternator uses a 2 pin connector and runs off of a 5 volt reference signal which the PCM determines the alternator...
the GTO is supercharged via a magnuson tvs2300. I would not have that boost control you suggest. but I understand. In essence treat it like you would NA. keep part throttle tuning under Vacuum...
I would like some advice on steady state tuning. I have yet to write up the base tune for it but I will be setting the car into open loop via the HPTuners e40 pcm write up. I will be tuning for both...
I need help understanding fan control on this car. From what I have read on the stickies, my fans are discreet meaning I cant adjust their speed even though I have the tables available to adjust...
is there a method for calculating the true ETC value for this throttlebody? Or is it just a guessing game? I will try your value and test both modifying the ECT Scaler and/or the MIN Airflow tables...
Thanks for the advice. I will try it out and post results ASAP.
Trying to get a more stable idle. Tends to dip down low, especially when pulling out of gear to neutral coasting.
Idle Airflow tables are stock only thing updated was the ETC Scaler for the...
Getting ready to tune the car. There are no apparent leaks in the system but everytime I turn accessory power on only, fuel pressure drops to almost nothing like 5 psi as if there was a leak....
ok well I know its been about a year since this thread was updated but as it turns out the PCM failed. That's why it would not start in SD or respond to any changes in the tune files. Thanks for all...
I have always done all that but for some reason it just wont revert to SD. Map is good the car just run in. Even tho everything in the tune is commanding it to run speed density the car will not...
Done everything as you posted as is the proper way to confirm I am in speed density but the car turns over and the injectors shut down going to 0%duty cycle immediately after start up. Will post logs...
Disconnecting the MAF whilest the car is commanded to run VE only has not worked.
Supercharged GTO.
In speed density mode the car will not start.
I have been successful in tuning the car in MAF only but for some reason even tho the MAF is set to fail it doesnt. No check engine...
So I have the car on the Dyno and did a couple of WOT pulls.
Tvs2300 11-13psi
Nw 102tb
Lc32 inlet
Zr1 injectors
325lph fuel pump 55-60 psi part throttle
70psi WOT
Stock ls2
Cant figure out how to sync my wideband to the MAf lo and hi afr error histograms. I downloaded the files from the HP tuners tips sticky but I just cant get them to work on the scanner. attached is...
The car is a supercharged GTO manual
Stock Ls2
Supercharger
Lc32 102mm inlet

Its a stock cam motor. I am having some trouble trying to get the car idling smooth.
I...
Well guys I am in the same boat as before. I just cant seem to get the car to idle. With the new data I have been able to get the car to run longer but right after start up the RPMs drop and the car...

here are the tune and scan
Eaglegoat and CHuggins
your data got the car running! posted is the scan with the car idling . Its weak and stumbly but at least it ran. I am going to continue playing with the idle and airflow...
Thank You Eaglegoat. I am currently in the process of removing the injectors and reinstalling the previous injectors I had. Afterwards if the car shows inprovement with the og injectors I will plug...
