How to Unlock Mercedes EMS71 ECU with AutoTuner?

The Mercedes-Benz EMS71 is an Engine Control Unit (ECU) (also known as Engine Control Module) manufactured by Siemens/Continental.

The EMS71 manages various engine parameters like fuel injection, ignition timing, and air-fuel mixture to ensure optimal performance, efficiency, and emissions.
