    Ve tuning question

    I have a 6.4, headers, high flow cats, edelbrock supercharger, forged pistons and cam. At the beginning of summer i installed FIC 1000 injectors. The car runs good, but just trying to dial in the VE table, btw NN is off and I think VVT is disabled, the phaser limiter is disabled. I have an AEM wideband installed, but i have been adjusting the VE with LTFT+STFT, My question is why would the LTFT+STFT log which seem like to opposite of EQ error, or am i not understand every correctly. Or just doing it all wrong. log file is to large to post, I will have to make a shorter one

    the EQ error should be based on the difference between commanded A/F Mode and actual A/F. you will get crazy readings at part throttle as A/F is constantly adjusting.
    So use that data to dial in WOT. you use STFT and LTFT math to dial in your part throttle VE tables
