Immo off ME1.5.5 Bosch

The Bosch ME1.5.5 is a well-known engine control unit (ECU) that’s widely used in vehicles equipped with gasoline engines. This ECU plays a critical role in managing ignition timing, fuel injection, and engine performance to ensure optimal operation and efficiency.

Like many modern ECUs, the Bosch ME1.5.5 comes equipped with an immobilizer system, a security feature designed to prevent unauthorized vehicle use. The immobilizer ensures the engine only starts when the correct key or transponder signal is detected.
