In 2005 MAN introduced a new generation of engines with Common-Rail Systems. The 2 main ECU’s in these vehicles are - our already talked about EDC7 and FFR.

FFR module is responsible for:
- Intarder and engine braking;
- Cruise control;
- Accelerator pedal and clutch travel sensors;
- FGR (Vehicle speed control) / FGB (Speed limiter) switch.

In 2013 MAN introduced its new line of vehicles with Euro VI (6) technology along with a new EDC17 and PTM system.
