MHD Super License – BMW S63TU / B58 / S58

The MHD Super License is a complete flash tuning solution for modern BMW turbo platforms, allowing full DME calibration via the OBD port once the ECU is unlocked.
It provides flashing, monitoring, OTS map packs, and MHD+ advanced features in a single license package.

This is a flash-based tuning system, not a piggyback, meaning the factory calibration is directly rewritten while retaining OEM safety strategies and drivability.

• S58 – G8x M2 / M3 / M4, X3M / X4M

• S63TU – F9x M5, F9x M8, X5M, X6M

DME unlock required for 06/2020+ vehicles prior to flashing.
