    Nag1 Gear ratio Change

    I just had to install a new TCM in my 2013 Charger RT and I am trying to change the gear ratio in the TCM so that I can start the adaptive learn process. I have downloaded the TCM tune but I can't find how to change the gear ratio.

    I appologize for possibly being a moron. I am still trying to learn how to use this program.

    Thx Walt

    You can do it in VCM Scanner. Got to Vehicle>Controls & Special Functions. It does not require writing a tune into the car.
