Rather than risking bricking my factory ECM (2015 Corvette Z06 A8) I was thinking I'd grab a spare PCM for $165 from RockAuto and then copy my virgin factory tune over to it. A couple of things I don't know, hoping people can answer for me:
a) Can I just read the factory ECM, plug in the blank new one, license it, and write the tune?
b) Does doing this set the VIN and so on? Or do I need to go a dealership and convince them to set the VIN with a Tech-2 before I can write it?
c) Can I do (b) on my own with a J2534 adapter and a subscription to acdelcotds.com or similar?
Thanks! Just trying to figure out the steps needed to "bootstrap" a brand new, blank ECM that I pick up from RockAuto or similar.
Thanks,
Dave
