    MM3 question

    Just got my MM3 and installed it. Watched a lot of vids and something I may be over thinking, but I can't find any answers to.

    When it says "flash just once" or "flash every time you start the truck". The flash only once. Does that mean you flash it once and it stays on that flash for good until you change it, or does it mean you flash it once and on the next start up you need to pick another flash? When you flash it "only once" does it stay on that tune or flash it once and forget it? I want the 120hp tune so not sure if I should "flash once" or if I should set that to flash on every start up? I would think flash once would flash it and keep it in there? I can't imagine software that would require a flash every start up and not stay in the ecm? Just curious. Thanks everyone!

    Re: MM3 question

    Ray prefers you hit “send only once” rather than at “every key on” .
    There is a thread or two on the topic, i can try to find where it is, I know I had issues with it but it was a easy fix... whewwww LOL...
    Is the 120hp going to be your default tune ?

    Re: MM3 question

    My default on my MM3 is set @ 60hp tune (which is what I chose) so yes every time I start it it starts on 60hp.
    Now if I choose to change the tune then I can change it to my other tunes such as 90hp normal or 90hp12v tune or 120hp at any time AFTER start up, makes sense ? Sometimes my fingers get carried away LOL, sorry
