Hello, I am new to this forum. I just had my hemi rebuilt with out the mds crap on it. The engine is in the car and I'm getting codes due to the mds delete. I have already bought the MPVI2 with the 2 credits required. I have lynqed it with the OBD2 connection. I can read the info as the car is on. I need to save the stock tune in a file and then go in and turn off the mds. It seems simple enough but it is very confusing when you're looking at all the info being displayed. Does anyone have a step by step guide to do this? Thanks in advance.
