At ECU Maverick, we provide a professional Plug-and-Play service. We don't just sell you the hardware; we transfer your vehicle's critical security data to ensure the unit is 100% synchronized with your existing EWS/CAS system. ISN & VIN Synchronization: We perform a full data clone or ISN (Individual Serial Number) transfer. This ensures your key and immobilizer system recognize the DME immediately.No dealer "marriage" or expensive coding is required. Simply install the DME, and the vehicle will start and run with all factory options retained.
