MHD F+G Series

The MHD Flasher F+G Series: Comprehensive Flash Tuning for BMW and Toyota Supra A90

The MHD Flasher F+G Series is a complete flash tuning solution for your BMW and Toyota Supra A90. Unlike add-on modules, it directly remaps your vehicle's engine control unit (DME), preserving all original safety features. This ensures optimal performance, safety, and handling.

Effortless OBD Flashing:

Install MHD at home and start tuning immediately! The MHD Flasher F+G Series app, using a MHD WiFi adapter and your car's OBD-II port, completes the initial installation in under 5 minutes. Subsequent map changes take only 20 seconds. Factory settings are easily restorable at any time; no initial backup is needed.
