M-Engineering PDK2 calibration for Porsche 971 Panamera models optimizes transmission behavior for higher-performance applications. Calibration changes include quicker manual-mode paddle response, increased clutch pressure and clamping capability, virtual-gear changes, and application-specific launch or shift-RPM adjustments. This service requires the PDK2 module to be removed and sent to M-Engineering and is intended for vehicles using M-Engineering ECU tuning.
