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

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

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