MHD F+G Series

The MHD Flasher F+G Series is a comprehensive flash tuning application designed for BMW and Toyota Supra A90 vehicles. Unlike piggyback modules, it offers complete DME remapping while preserving all original equipment manufacturer (OEM) safety features. This ensures optimal performance, safety, and drivability.

Full OBD Flashing: Conveniently install MHD at home and begin tuning immediately. Simply download the MHD Flasher F+G Series app, connect via a MHD WiFi adapter and your vehicle's OBD-II port, launch the app, and complete the initial installation in under five minutes. Subsequent map changes are even faster—a mere 20 seconds! You can revert to the factory OEM flash at any time; no initial backup is required.
