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: Install MHD conveniently at home. The MHD Flasher F+G Series app connects via a MHD WiFi adapter and your vehicle's OBD-II port. Initial installation takes approximately five minutes; subsequent map changes require only 20 seconds. Factory OEM flash reversion is possible at any time, eliminating the need for initial backups.
