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 ordering an ECM/ECU online, but this unit for my 2018 Chevy Sonic arrived quickly and worked perfectly right out of the box. The VIN programming matched flawlessly, so installation was truly plug and play with no hiccups. After swapping it in, my car fired up immediately and all the electronic systems ran smoothly without any warning lights or errors. It’s great to know I didn’t have to spend hours troubleshooting or paying a mechanic for something I could handle myself. Definitely a reliable solution that saved me time and stress.

I bought this ECM for my 2018 Chevy Sonic and it arrived quickly, well-packaged, and ready to install. The VIN programming was spot on, so it was literally plug and play with no headaches or additional coding needed. My car started up right away and runs smoothly now—definitely worth it if you want a hassle-free replacement. The customer support was helpful too when I had a couple of questions before ordering.
