Description
MHD Tuning is a mobile-based ECU flash tuning and performance software platform primarily for BMW (and some Toyota Supra) engines, letting owners remap their engine control unit (ECU) via an Android or iOS app connected to the car’s OBD-II port using a compatible adapter.
With MHD Flasher, you can:
• Flash ECU tunes (stock or performance maps) to unlock more power, improved throttle response, and better drivability.
• Use pre-built Off-the-Shelf (OTS) maps or support custom tunes from tuners.
• Monitor engine data live with configurable gauges and logging.
• Read and clear fault codes and reset adaptive parameters.
• Revert to stock calibration at any time without needing a separate backup.
Licenses (e.g., Super-License) unlock full features and map packs for specific engine types, and typical supported BMW engines include N54, N55, S55, B58, S58, S63, and N13.
In short, MHD Tuning turns a smartphone into a powerful tuning and diagnostic tool for enthusiasts who want to safely optimize performance and customize engine behavior on supported vehicles.
