Alright I've been trying to figure out what I need to do to get this lb7 ECM working!! When I first tuned it it worked fine, then I put another tune in it and it wouldn't start and the anti theft light was on. We reset it and drove it to the dealership and they reflashed it. Now when I try to tune it, it says this and gives me a incomplete vin.
I've tried alt keys and everything else I can think of. I didn't lock it with a custom key though?? Any ideas??
