M-Engineering ECU Tune for Porsche Panamera 976 2025-2026

M-Engineering's ECU calibration for the 2025 and later Panamera, the 976 generation, improves throttle response, revises torque management parameters and removes the top speed limiter. M-Engineering lists the Panamera base car, Turbo and Turbo S E-Hybrid for this product.

These cars use the locked H80 MG1 ECU. Installation is a bench procedure: the ECU is removed and sent to M-Engineering HQ, flashed and returned, typically about 24 hours after it arrives. M-Engineering notes that the locked H80 MG1 ECUs have a longer workflow to unlock and flash, which means more downtime than older Panameras.

M-Engineering has not published 976-specific power figures, so none are quoted here; results depend on the model and condition of the car. Order this product rather than the 971 tune if your Panamera is a 2025 or later model.

Frequently asked questions

Is this a bench flash or an OBD flash?
Bench. The ECU is sent to M-Engineering HQ and returned, usually about 24 hours after it arrives, though the locked H80 MG1 ECU adds a longer unlock workflow.

How much power will I gain?
M-Engineering has not published power figures specific to the 976 Panamera, so no number is claimed here.

Will the 971 tune work on my 2025 Panamera?
No. 2025 and later Panameras use the locked H80 MG1 ECU and need this product.
