Flex, bflash, CMD and many other tools don’t have bench protocol for the Mercedes Continental EMS71 ECU. Autotuner now released an unlock service for the MB EMS71 ECU.
The Mercedes-Benz EMS71 is an Engine Control Unit (ECU) (also known as Engine Control Module) manufactured by Siemens/Continental. It’s primarily found in newer, smaller displacement Mercedes-Benz models, specifically those with the M282 engine, such as the A-Class (W177), B-Class (W247), CLA-Class (C118), GLA-Class (H247), and GLB-Class (X247). The EMS71 manages various engine parameters like fuel injection, ignition timing, and air-fuel mixture to ensure optimal performance, efficiency, and emissions.
