TCM callibration needed - 2015 GMC Sierra

[mungovan]

Cant write intial stock tune. Attached info.xml. Truck has only 600 miles on it. Never tuned this early before....

if this is an 8 speed trans, click the red X to skip tcm, it is not yet supported for tuning.

Thanks

[mungovan]

it is the 8 speed but I dont think it gave me the option to bypass the step of writing the stock tune. I felt like it was in a a continual loop. Write, fail, either X or check brought me back to the start. I will try again this evening.

Is 8sp support coming?

It will happen eventually, yes.
