Thread: MM3 Question

    MM3 Question

    I recently bought my first Cummins, it's a 2013 2500.

    It was fully deleted (best I can tell anyway) when I bought it.

    I noticed that it had a cable running up to the dash where a screen used to plug into after following it down I learned the was a MM3 box under the dash.

    So I contacted MM3 and ordered a new screen but now my problem is the only tune I have is whatever tune was on the truck when they took the original screen.

    Is there anyway I can figure out who tuned the original screen and contact them about buying another copy of the tune or am I just gonna have to abandon the tune I have and get new ones?

    Thanks for any help.

    In your case, you'd need new tunes.
