    MM3 Help

    So I got a 2013 RAM 2500 with MM3 tuner but I don’t understand how to use it noe did the last owner.

    One problem I have it constantly turn off another is I need help understand what each tune does.

    Have you check all the connections and checked the wiring for knicks?

    Final part I would check is the connection between the black box components.

    It splits in two and if the posts are still installed take them out.

    Have you called MM3?

    They should be able to help you sort out why you are losing communication.

    Going to be a little tougher on the tunes.
