The EMS SDI 3.1 engine management system ensures optimum engine performance at all times.

In particular, it controls the position of the electronic throttle valve (ETC) – a prerequisite for compatibility with the Porsche Stability Management (PSM), which comes as standard. Moreover, it regulates all engine-related functions and assemblies (see diagram). The results: optimum fuel economy, emissions, and performance in all driving situations.

Another important function of the system is cylinder-specific knock control. Since the six cylinders never all work under exactly the same conditions, they are monitored individually by the knock control. The ignition point is shifted individually, as and when necessary. This prevents damage to a cylinder or piston at high engine speeds and loads. The on-board diagnostics, which are compliant with European standards, ensure timely detection of any faults and defects that may occur in the exhaust and fuel systems and notify the driver immediately. This also prevents increased pollutant emissions and unnecessary fuel consumption.
