    E38 ecu 2012 GM LS3 Gen 4 Idle tuning

    I'm getting closer to a good idle. have surging up and down. Just noticeable.
    Over 3k runs very well.

    I need for someone to look at my files for changes to be made.

    5.3, Chuck Norris Truck cam and springs, Airraid Air intake tube w/stock MAF. is Flex fuel. And he wants it tuned on 87! Just a street Truck, 6L80

    The VVE does not look tuned. It still has VVT stuff active in it.

    If you tune this it will make world of difference down stream.. Idle included.

    you still have vvt?

    after doing a quick research, to disable it you want to make changes to
    Engine>Airflow>Variable Camshaft>Enable Conditions

    Id wait for a 2nd confirmation to ensure this is correct though.
