51918358 – Engine ECU ENGINE CONTROLLER Fiat 1.3 Multijet MJD8F3.F7 VIRGIN
51918358 is an original engine ECU ENGINE CONTROLLER used in vehicles of the Fiat group equipped with the 1.3 Multijet / 1.3 JTD engine. The module operates in the Magneti Marelli MJD8F3.F7 system, which is responsible for managing engine operation, fuel injection, turbocharger control, the EGR system and communication with other vehicle modules via the CAN bus.
The offered controller is prepared in the VIRGIN version, which means that the immobilizer memory has been cleared and the module behaves like a brand-new controller from the factory. After installation in the vehicle, the controller automatically programs itself to the car and stores the immobilizer data and VIN number without the need for manual coding.
The VIRGIN = PLUG & PLAY solution means simple installation – just connect the controller in the vehicle and the vehicle system will automatically save the required configuration data.
