Signal specification
Certain values deviate from those contained in the signal specifications, see Signal specification . This is because read off values are calculated and filtered by the control module. In certain cases the engine must be running to obtain the relevant values.
Torque control
Torque reduction occurs through control of the ignition and is used to lower the engine torque while shifting for smoother gearshifts and longer service life. Torque reduction is activated at the same time that shifting starts.
Measurement range: 0 - 511 Nm
Engine torque
The signal displays the calculated output torque of the engine.
Measurement range: -512 - +511 Nm
511 = No torque limiting request
Torque limiting requested
The signal displays torque limiting and is used to limit the torque of the engine continuously in those cases where the maximum permitted torque limit of the gearbox would otherwise have been exceeded. To reach the desired reduction level the engine control module (ECM) uses a mixture of ignition reduction and throttle control.
Measurement range: -512 - +511 Nm
