Good day, car is a 07 Ford Mustang GT, have no issue connecting it last 2 days while i was doing MAF calibration with it. Today when i want to connect and upload the latest tune i have to teh car, it doesnt wanna communicate with the PCM. Tried connecting for datalog, doesnt work too. When i plug the MPVI2 into the OBD2 slot, the unit's light came on, so im assuming power is good. Anyone know the fix for this?:(
Found a solution..
Step 1. Reload MPVI2 (under Help tab on Editor)
Step 2. Attempt to load in the tune to ur pcm.. The device will prompt u to use ur credit.. go ahead with the credit use.
Step 3. Start using MPVI2 like a champ.
happened to me today from using the mpvi2 to the mpvi 1, and not even turning off the laptop helped, what I did was that I unplugged the mpvi from the car and the laptop and then reconected them . Or try the resync interface option
