An Expert’s Note on VIN Programming
“In my 20 years of diagnostics, I’ve seen countless DIYers install a used computer from a salvage yard only to find their car won’t start or the transmission shifts erratically. On these 90s GM vehicles, the ECM is not just a part; it’s the brain that’s coded specifically to your car’s options, engine, and security system. Our VIN programming service isn’t just a convenience—it’s the critical step that makes the repair successful. We ensure the ‘digital handshake’ between the module and your car is perfect, so you get a reliable, lasting fix the first time.”
