Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.

Strict Testing & Quality Assurance
Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
Complete communication & CAN-bus verification
Sensor input/output and signal integrity checks
Injector & ignition pulse simulation
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 a bit nervous about ordering an ECM/ECU online, but this unit for my 2019 Chevrolet Suburban arrived quickly and was truly plug-and-play. It fit perfectly and the VIN programming was spot on, so the truck started right up without any hiccups. I appreciate how straightforward the installation was, even for someone like me who’s not a mechanic. The customer support team was also very helpful, answering a couple of questions I had about the setup. Overall, this made a frustrating repair way easier than I expected. Highly recommend to anyone needing a reliable replacement!
