MM3 Tuner

**BSTOUMBAUGH** · 05-02-2019

I just bought my 2013 ram 3500 mega cab dully Monday and it has a MM3 tuner on it.

I know nothing about it or who put the tune on it,what tune is on it, or even how to work it really.

By the way I bought the truck off our used lot it was a trade in. so no former customer contact.

Thanks.

No contact what so ever who owned the truck before? Is this a car dealership it was purchased from? They have to have some kind of info who owned it I would think?

2016 Ram Laramie 3500, G56, 6.7, MM3 by Double R Diesel, Rough Country Leveling, 35x12.50 Nitto G2, HID headlights and fogs plus many many other add ons.....

Let's see what the ecm file name is, it might help us find out at least who tuned it.

1. Turn ignition to run(don't start truck)
2. Wait 10 seconds
3. Tap anywhere on screen.
4. Tap "Main Menu"
5. Tap "ECM Tuning"
6. Tap "ECM"
7. Tap "Program Custom File To ECM"

What does it says the file name is? It should say something like johndoe.ecm or companyname.ecm etc.
