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 really impressed with how quick and hassle-free the installation of this ECM/ECU was on my 2013 GMC Sierra. It arrived faster than I expected, and everything came pre-programmed to my truck’s VIN, so I just plugged it in and went. The engine runs smoother now, and all the check engine lights stayed off after the swap, which gave me peace of mind. Their customer support was also helpful when I had a couple of questions before ordering. Overall, this was a smart buy that saved me a lot of time and frustration.
