New Mini Maxx Tuner Stuck on Initializing Communication?
Unplug the tuner from the OBD port. Sloooowly plug it in until it beeps. Stop there. The objective is to get the two longest pins (power) to be the only ones making contact. Once powered up press the top left button (menu) and then scroll down to change truck. Select that and set it to your truck make and year. Save that. Plug the tuner the rest of the way in and download the truck.
