It has;
L99 DoD/afm delete
cam phaser locked
PRC heads / Cam
80lb injectors bosch
LSXR 102 intake and nick williams 102MM throttle body
headers, no cats , mufflers
supposedly a circle D converter but I have my doubts
car is on 93 octane no flex fuel at the moment.
has fuel pressure regulator but not sure on in tank pump size etc.
I attached the initial tune I pulled from car and attached a log of a short drive around neighborhood.
Car would chirp putting it into gear, would stall at stop signs and when hot would randomly start hunting the idle up and down at the end of the log.
While I was scanning and logging I *may have commanded a higher idle from the scanner and maybe reset LTFT/ or turned them and STFT off temporarily but you can see the issues.
The other tune and log is after I did some maf changes and tried to put lipstick on a pig trying to mix tune files a little bit.
I read about setting up the Fast intake manifold and 102mm tb by changing the idle ETC area scaler to 7300 and the dynamic airflow volume to 796cu in which made a nice improvement.
My inability to find a stock tune file and implement changes for 80lb injectors, Fast 102 intake and , NW102 tb with a mild cam is frustrating me but I have a GenV LT so never spent much time on LS/L99 etc.
Would really appreciate someone willing to whip up something basic I can try out that keeps a lot of the stock ECM characteristics. Here is a short youtube clip of after I made some changes and forced closed loop.
Fueling is off and ordering a new map sensor for him and AEM 30-0334
