About MHD F+G Series
The MHD Flasher F+G Series is a complete flash tuning app for your BMW. Unlike a piggyback module, it is capable of complete DME remapping while retaining all OEM safety mechanisms. This allows for maximum performance,maximum safety, and unrivaled drivability.
---------------------------------------------
Full OBD Flashing:
You can install MHD right at home and start tuning immediately! Simply download the MHD Flasher F-Series app that connects via a MHD Wifi adapter and your vehicle’s OBD-II port, start the app, and within 5 minutes the initial installation is complete. Further map changes are much faster - only 20 seconds! You can revert your vehicle to the factory OEM flash at any point, and no initial backup is necessary.

Great app easy to use and very convenient , maps are all amazing and a huge notice in increased power! highly recommend
