Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with our cloning service.
Built to OEM standards for reliability, calibration accuracy, and long-term performance.

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.

Perfect fit and worked flawlessly right out of the box—couldn’t ask for a smoother swap. Super fast delivery, too!

I was a bit nervous about replacing the ECM on my 2008 Mercedes S-Class, but this unit made the process incredibly straightforward. It arrived quickly and was already programmed to my VIN, so installation was truly plug and play with no hiccups. The car started up perfectly right away, and I haven’t had any issues since. Definitely a reliable and hassle-free solution.
