Hey guys, Quick question here. Have an LMM with locked tunes from Danville. Begged for the code just to be able to adjust some things for driveability in the TCM. Mainly part throttle upshifts and lock/unlock points. Understandably they refuse to let the code out so I am stuck with what I have.

My main question is if I reflash or "write my own" tcu tune, will it be able to work correctly with locked ecu tunes?,
