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

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.
