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.
