This are the most important functions that are optimized
Ignition control To use the fuel in a effective way, it's important, to calculate all the time the best possible timing in relation to the RPM, load, temperature and other control signals. At diesel engines - the optimal injection pressure.
Injection control In Relation of the available amount of Air, RPM, load and other correction factor, the electronic calculates the needed injection time and amount. This ensures the reduction of fuel consumption, a reduction of emission, and a gain in the engine power.
Charge pressure control At Turbocharged engines, additionally the charge pressure is calculated to raise the benefit of the above explained settings.
