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 recently replaced the ECM on my 2007 Chevrolet Avalanche with this VIN-programmed unit, and I couldn’t be happier with the results. The installation was straightforward—just plugged it in and everything fired up without a hitch. It was shipped quickly and arrived well-packaged, which gave me confidence right away. After driving for a few weeks, I noticed smoother acceleration and no more warning lights on the dash. Overall, it’s exactly what I needed to get my truck back to running like new without any hassle.

I was a bit nervous ordering an ECM for my 2007 Chevy Avalanche, but this one arrived quickly and was already VIN programmed, which saved me a ton of hassle. Installation was straightforward—just plug and play as advertised. Once everything was hooked up, the truck fired right up and ran perfectly with no error codes. It’s clear the sellers know their stuff, and their tech support answered a couple of questions I had along the way. Overall, a smooth experience that got my Avalanche back on the road in no time. Highly recommend!
