2017 C7 Corvette GS with A8 (TCM Error at Backup)
Posted: Sat Nov 04, 2017 8:18 am
Good day all. I have the C7 in the subject and am able to apply the Diablo tune modified with AFM set to off. However I had to set the Trinity vehicle options to Manual Transmission since it would give an error when trying to backup the TCM. New to the whole tuning thing and look forward to some changes later. I know that the 2017 is now supported including the A8 but understand that all the various combinations can cause initial issues. Backup files and vin attached.
