What is the CPC Module and what does it do?
The CPC (computer powertrain control) is the powertrain control unit,
another control module that is somewhat similar to the ECU (engine control unit).
In modern Mercedes vehicles it is responsible for controlling multiple vehicle
features such as the active exhaust valves, throttle pedal, and speed limiter.
It is also home to several torque limiters that used to solely be in the ECU.
Benefits of doing a CPC upgrade?
While it does not directly control the engine, the torque limiters
in the CPC restrict what the ECU is able to do, when controlling the engine.
The Weistec CPC is a complete replacement for the original CPC module. It has the torque
limiters set to values that effectively "remove" the limits, allowing the ECU to operate with
fewer restrictions when it comes to making power. The speed limiter is also removed, allowing
higher top speeds. When requested, it can even be set up so that the active exhaust valves are
always in the open position. The Weistec CPC is also a great compliment for any tuned modern Mercedes
vehicle offering better and more consistent performance and higher top speeds.
Please email your VIN to tuning@weistec.com so that we can verify compatibility with your specific vehicle.
