    Nope - not sure what else you could optimize besides spark on deccel. It works just fine with DEFCO turned off.

    Not sure where to find this spark on decel table on 15+ !, as what i heard it's all torque based with these cars.

    Just increase the spark in tables for low Load.

    Hi All,

    Got it done now getting decent pooping after 3000 rpm, and put some nice chopped idle effect to it as well.

    Thanks to all who have tried to help

    The borderline and mbt tables to not need to be changed. Spark decel on the 11-14 coyotes is set to 60* across the table to allow torque control.

    Disabling DEFCO and lowering spark decel will make your exhaust pop. You may need to test spark decel around 650 to 1250 or spark will be high enough for the car to drive itself.

    750 - 17
    1000 - 14
    1500 - 12
    2000 - 12
    3000 - 12
    5000 - 25
    7000 - 28


    The 15+ do not have this table and is purely torque based. Disabling defco should make the popping sound. Torque control will retard timing for engine braking.
