Mercedes-Benz CPC tuning

CPC module reprogramming to remove torque and top-speed limits — required for many 2020+ Mercedes for Stage 1 / 2.

The CPC (Central Powertrain Controller) is a control unit fitted to modern Mercedes-Benz cars — diesel, petrol and AMG. It receives data from the vehicle network (coolant temperature, speed, torque, pedal position, exhaust flaps, boost, cooling system status) and stores torque limits, top-speed limits and other restrictions that are independent of the engine ECU.

On cars with recent CPC software (most 2020+ vehicles) a traditional Stage 1 ECU remap may give little or no improvement, because the CPC keeps limiting torque. Modifying the CPC lifts torque, boost and top-speed limits so the tune can work fully.
