Trionic 8 calculates how much power the driver wants as early as possible to avoid turbo kick or lag, therefore making driving smooth. As the driver depresses the accelerator pedal, it acts on a pedal position sensor integrated in the pedal bracket. This information, in the form of a

The torque request is then processed by the ECM with regard to current operating conditions and limitations. The result is an air mass request to achieve the torque requested by the ECM. The driver's requested torque can be higher than that requested by ECM when, for example:

Used to engage generator charging with a certain delay after starting and in certain cases disengage generator charging. In this case, the engine load will be reduced temporarily when idling to stabilise the idling

so that the correct torque is attained, i.e. air mass per combustion. Fuel injection is sequential and regulated with air mass per combustion and engine speed as parameters.
