Long time user here. I've lost count of how many times I;ve flashed this car. 2002 Z06. Car has been down a while. Yesterday the car fired up just fine after sitting. Today I charged the battery for about an hour before I tried to load a tune. Tune kept failing to write. I hit abort, and I tried again but got the same result.
Now turning the car to run gives me a reduced engine power message and the fuel pump cycle is interrupted. HPT is unable to locate the VCM. Suggestions? I don't really follow wtf was so different this time. I have in fact had to abort, and HPT kicked into recovery mode successfully. It did not try to this time.
