MHD F+G Series

The MHD Flasher F+G Series: Complete Flash Tuning for Your BMW

The MHD Flasher F+G Series is a comprehensive flash tuning application designed specifically for your BMW and Toyota Supra A90. Unlike traditional piggyback modules, this solution performs full DME (Digital Motor Electronics) remapping while preserving all original equipment manufacturer (OEM) safety protocols. This approach delivers maximum performance, optimal safety, and superior drivability.

Full OBD Flashing

Install MHD from the comfort of your home and begin tuning immediately! Simply download the MHD Flasher F+G-Series app, connect it via a MHD WiFi adapter to your vehicle’s OBD-II port, launch the application, and complete the initial installation in just 5 minutes. Subsequent map changes are significantly faster, taking only 20 seconds. You can revert your vehicle to the factory OEM flash at any time, and no initial backup is required.
