Strict Testing & Quality Assurance

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 equipped with IMMO (Immobilizer) or PATS (Passive Anti-Theft System) may require additional key programming after installation. This is normal for models where security data must be synchronized with the vehicle’s body control system.
For a 100% plug-and-play solution with no relearns, no key programming, and no compatibility issues, we recommend our ECU Cloning Service, which transfers all original security, immobilizer, and configuration data directly into the replacement unit.
