Hello all.
I'm sorry if this has been talked about. I searched and didn't find my answer.
Ive bought an MM3 with tunes from DRD and installed the tuner on the truck.
Now my buddies wanted tunes, so I purchased two more tune packs with different VINs but was unsure how to unlock the VIN to tune the other trucks.
Also, how would I switch back to one of the other trucks after there all tuned?
Please help me and TIA.
