An Expert’s Note on VIN Programming
“Many people think they can just grab a used computer from a salvage yard and install it. Unfortunately, on modern GM vehicles, that’s a recipe for failure. The ECM is tied directly to the vehicle’s anti-theft system (VATS/Passlock) and has specific calibrations for your engine and transmission. Without proper VIN-programming, the car simply will not start. By ordering a Programmed 12651994 ECM from us, you’re not just buying a part; you’re buying a complete solution that bypasses this major roadblock, saving you time, money, and a massive headache.”
