Thread: MM3 Install Question

  1. Top Of Page | #1

    MM3 Install Question

    OK guys and girls, so I just got my MM3 from Ray and plan on installing it and the exhaust this weekend.

    My question is once I load the tune can I pull all of the wiring and boxes for the MM3 out or do they need to stay in?

    I know you can remove the display but do the boxes and the wire to the engine bay need to stay?

    Thanks for any help!!

    Email DRD as I only know you can pull the monitor for sure.

    If you find your answer post it on here for all others.

    Thanks.

    Do you mean the unlock cable?

    Once you program the ecm successfully you can remove the entire tuner system if you want. The truck will stay "tuned". You just simply will not be able to make any further tuning changes with the tuner removed.
