Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with our cloning service.

Injector & ignition pulse simulation
Power, ground, and load-circuit analysis

Important Note
Some vehicles with IMMO or PATS require key programming after installation. This is normal.

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 ordering an ECM online for my 2012 Jaguar XJR, but this company made the whole process really smooth. The ECU arrived quickly with free shipping, which was a nice bonus. It came VIN programmed and ready to go, so installation was straightforward without any extra hassle. I also appreciated their clear communication—they kept me updated every step of the way and answered all my questions promptly. After swapping it in, my car runs perfectly, just like new. Highly recommend if you need a reliable replacement!
