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.

Swapping out my old ECM for this VIN programmed unit was surprisingly straightforward. The plug-and-play design made installation a breeze, and the car started up without any error codes or issues. Shipping was quick, arriving well-packaged and on time. Overall, a solid product that restored my E-Class to perfect running condition.

I was a bit nervous about replacing the ECM on my 2010 E-Class, but this unit made the whole process surprisingly smooth. It arrived quicker than I expected, and it was already programmed for my VIN, which saved me a ton of hassle. Installation was straightforward — truly plug and play, just like advertised. My car fired up right away and runs perfectly now, no warning lights or errors. Big relief and definitely worth the investment!
