Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I was a bit nervous about replacing the ECM on my 2014 Chevrolet Express, but this unit arrived exactly as described and was already VIN programmed, which made installation a breeze. The plug-and-play design meant I didn’t have to mess with complicated wiring or extra programming tools. Shipping was surprisingly quick too, so I was back on the road in no time. I really appreciated the clear instructions and even reached out to tech support with a couple of questions—they were helpful and patient. Overall, this was a smooth experience and my van runs perfectly now. Highly recommend to anyone needing a reliable replacement part!
