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 require key programming after installation. This is normal.
For a 100% plug-and-play solution, we recommend using our full cloning service. We transfer all security data to the replacement unit.

If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

I had been struggling with my Silverado’s ECM for weeks, and finally decided to order this replacement unit. The best part was the programming service included—they had it VIN programmed and ready to go right out of the box, which saved me a ton of hassle. Shipping was also super quick and didn’t cost an arm and a leg, which I really appreciated. The moment I installed it, the truck fired up without any issues, and all the previous error codes disappeared. Their team was very responsive too, answering my questions promptly when I reached out for clarification. Overall, this was a smooth and reliable experience from start to finish.
