The Bosch ME 9.6 engine management system can be used for the engine variants with either 230 hp/??? kW or 250 hp/??? kW, although with different software content. The main task of ECM is to regulate torque (air mass), fuel and ignition. The control module is mounted on the plenum chamber of the intake manifold and is connected via two 64-pin connectors - one to the car's wiring harness and one to the engine's wiring harness.

The software in ECM can be updated via SPS.
