Trying to reflash a used E37 PCM from a '10 Impala to accept a new OS and VIN for an '08 Cobalt SS. Have licenses for both the PCM I'm trying to reflash and the new VIN/OS combo. The OS loads fine on a complete rewrite, but I'm still getting the "vehicle not licensed" error when I try to reprogram the VIN. Went back to the original OS on the PCM and get an error that the BIN is not compatible with the OS (08 Cobalt vs. 10 Impala V6). I need a workaround and hoping I didn't just waste two credits on the Impala PCM.
Also tried to get a stock reflash based on the '08 Cobalt VIN at the dealer. Service tech said they can't do it without the actual car, which I don't have since this is going standalone. Where can I get a reflash on the PCM with it out of the car?
Thanks!
