    not related but u need to put the stoich table back to stock as u have the flex sensor enabled but 14.68 in all cells so ur going to go super lean if u put e85 in the tank, also ur not maf failed properly its kinda half done, also how low did u go in the PE ? try 10 in all cells and u should hit PE about 35-40% actual TPS in that closed loop log u hit PE at almost full throttle

    If it supposed to be in SD, you need to go to Engine Diag--Airflow--Mass Airflow--and change 14,500 to 0 and the 1100 number under that to 1. Then go to DTC's and change P0101,102,103 to Mil on first error, not no mil lght.

    How are your fuel trims looking? I have noticed this ecm won?t go into PE when the fuel trims are off by more that 20%

    Hasn?t always been the case but has happened to me on 3 different cars.
