Power, ground, and load-circuit analysis
Flash memory integrity and checksum validation
Thermal and voltage-stress testing to confirm reliability

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 nervous about replacing the ECM on my 2009 Chevy Express, but this unit made the process incredibly simple. It arrived quickly and was already programmed to my VIN, so all I had to do was plug it in and go. The engine runs smoother than it has in years, and I haven’t experienced any hiccups since the swap. It saved me a trip to the mechanic and a lot of hassle. Definitely recommend for anyone needing a reliable ECU replacement.
