I have an 08 HHR SS LNF that the ecm went out on. I however do have a copy of its tune backed up. I bought another ECM. My question is if i flash the backup from my orginal onto it will it change the vin and all? I am not at all use to this ECM. Or if anyone has recommendations as for what I need to do to unlock it so it will work on my car that would be great.
