Have done many tunes on older GM ECMs but this is my first crack at OBDII.
Just received my VCM tuning suite this week and will get going scanning and making changes to my 3800SC program shortly. However, I just spoke to another new HP Tuners user and he advised that its easy to wipe out a GM PCM under certain conditions like if the PCM loses power during a data exchange. He's already wiped out several PCMs, I assume by pressing the wrong buttons or not using the right procedure.
For the new users like myself what the best advise that you can give to insure that I keep the PCM in good health while tuning. A few simple tips would be appreciated.
I am loading the program into my laptop this morning. Thankjs
