Calculation of load factor
The load factor of the engine is determined as a percentage from the rack position at idling (Ridl), maximum
rack position (Rmax), minimum rack position (Rmin) and actual rack position relative to Rmin (Ract). See
Figure 2-32.
The calculated load factor is delivered as a PWM signal from an E-ECU terminal or through CAN
communication.

low idle
Ract >= Ridl
Load=(Ract-Ridl) / (Rmax-Ridl)*100[%]
Ract < Ridl
Load=(Ract-Ridl) / (Ridl-Rmin)*100[%]
