The CPC Torque limiter functionality allows the user to limit the torque output of the ECU, so even if a tuner manages to achieve higher, more efficient toque curve figures, the ECU will still be hindered by the CPC. There are built-in limitations and the ability AVDI ofers is to reach said limits. Here is an example: Mercedes W206 C180. The car comes with a torque capacity of 250 N m (184 lb ft) at 1,800–4,000 rpm but a tuner can achieve 500 Nm of torque The CPC of this car in its factory form is set to a maximum of 300 Nm (just to be safe for overboost applications) and the maximum capacity the CPC can be unlocked to is 420 Nm, so the tune applied to the ECU must be created with that in mind, it will not be able to spread to its full potential.
To make the desired changes, you enter the Special Functions menu after selecting the model you’re working on and them select the “Torque Limiter” option. Make the desired changes and then click the
“Write” button to save them
