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
Flash memory integrity and checksum validation

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.
