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.

Swapping out the ECM on my 2013 Chevy Express was something I was nervous about, but this unit made the whole process surprisingly smooth. It came already VIN programmed, so I just plugged it in and everything fired up like a charm. I love not having to deal with complicated setups or extra trips to the dealer. Shipping was quick, and the customer service was really helpful when I had a couple of quick questions. Overall, it felt like buying a high-quality part from someone who knows their stuff. Definitely recommend if you want a no-hassle replacement.
