2005 GTO, 402 motor, mp122 blower, cam heads, etc. Car is tuned and running good with one exception...when its warm, the throttle refuses to be more open than 11% TPS on startup. Even with cranking VE, cranking airflow, minimum running airflow set to very high or even max values, the throttle stays at 11% and it wont fire up unless you manually open the throttle.
Ive tuned similar setups like this before, without this issue. Any ideas?
Ive attached the tune, and a log of the TPS...you can see where I have to give it more throttle manually. It needs about 20-25% to start, 18% to idle when warm. 11% is nowhere near enough. No matter how I change those previously mentioned tables, it settles to 11%. The only exception...when I first flash a tune, it goes to 25% for the first crank over. After that, down to 11%.
Thanks for your help.
