Due to the growing need to control electronics in the later model Mercedes vehicles equipped with the 9-G Tronic, 9-Speed Transmission, Mercedes added a CPC (Powertrain Control Module) to handle some of these duties.
The CPC Module in your AMG has control over overall torque output among several other key functions. When tuning the ECU, the CPC Module will intervene and send the ECU several messages to decrease power via ignition timing and boost. When tuning the CPC, we can adjust these values to properly work with the ECU.
Other key features the CPC is responsible for is the exhaust flap control, vehicle speed limiter, intercooler pump flow, and HP/TQ display on your dash among others. The engineers at Premier Tuning Group provide a new calibration that optimizes these settings and allows your AMG to run even strong and more reliably.
This upgrade requires a new CPC module to be plugged into your vehicle and calibrated through OBD via our proprietary Verstand Software.
