MHD F+G Series

The MHD Flasher F+G Series offers a comprehensive flash tuning solution for your BMW.

MHD Flasher F+G Series is the complete ECU tuning application for your BMW & Toyota Supra A90. Unlike piggyback systems, it fully remaps the DME while preserving all OEM safety protocols. This ensures peak performance, safety, and drivability.

Full OBD Flashing:

Install MHD from home and begin tuning right away. Download the MHD Flasher F+G-Series app, connect via the MHD WiFi adapter to your vehicle's OBD-II port, launch the app, and complete the initial setup in about 5 minutes. Subsequent map changes are incredibly fast—around 20 seconds. You can restore your vehicle to the stock factory tune at any time, with no initial file backup required.
