Got a question, when i hook up my flashscan tool to my truck it will only read the ECM as an LBZ. By everything we have to identify which duramax is in my truck it is an LLY, the vin#, badges etc.. Does this happen often? I have no real issue with it, i can still tune and everything just fine, i just wondered if it is wierd that it reads as an LBZ?
