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 my 2019 GMC Terrain’s ECM, but this unit arrived precisely programmed to my VIN, making the whole process seamless. Installation was straightforward—just plugged it in, and the engine fired right up without any hiccups. I appreciated how quickly it shipped too, which saved me from being without my vehicle for long. The difference in drivability is noticeable, and I haven’t experienced any warning lights or errors since the swap. Overall, this was a smooth, hassle-free upgrade that got me back on the road faster than expected. Highly recommend this for anyone needing a reliable ECM replacement.

I was really impressed with how straightforward the installation was on this ECM for my 2019 GMC Terrain. It arrived quickly and was already programmed for my VIN, so I didn’t have to worry about any complicated setup. After swapping it out, my vehicle ran smoothly without any glitches. Definitely saved me a lot of time and hassle compared to trying to reprogram an old unit.
