Hello all, new to tuning here so I will get straight to it.
I got the MPVI2 and bought 2 credits, was able to read my Suburban looked at the data, only wanted to disable the DOD and a few of the codes associated with that physical change. saved the file, went to write to vehicle it told me I needed credits, found where that was and checked the box, told it to write to vehicle. Looked like it did but when I reread the vehicle it still shows me the original data and now says I have no credits. What did I do wrong?
Thanks for any help.
