2008 duramax U7186 update troubles
Posted: Wed Jul 25, 2012 6:18 pm
hi guys
I tried loading the towing tune in my 2008 duramax after the new update 9r15
I initially let the programmer download a backup of my ECU, then started the towing flash. The tune seemed to be loading fine, but after a couple minutes it said there was an error loading the program into the truck's ECU.
It said that it would restore the original tune. However, it failed to restore the initial tune as well. Clicking the info button showed the message: "ECM: Error unlock for reflash (-1)".
Is their a way I can fix this somehow??
I got a 2008 duramax 6.6L
