So, I had sent my ECM off for a mail order tune and I am not happy with it. It?s an extensive upgrade build on a 6.0 ls1 cam injectors and more...
I decided to go the MPVI2 route and start from scratch. I pulled a stock 6.0 tune to work with and now I can?t write the tune to my truck? I guess my question is about how the licensing works? I used the vin change wizzard as well
What am I missing here?
