MHD Flasher F+G-Series B58

The MHD Flasher F+G-Series is a complete flash tuning app for your BMW & Toyota Supra A90. 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.

You can install MHD right at home and start tuning immediately! There is no need to remove and send out your DME for a costly “unlock.” Simply download the MHD Flasher F+G-Series app that connects via a our MHD Wireless Adapter (or KDCAN cable) to your Android device and your vehicle’s OBD-II port, start the app, and within 3 minutes the initial installation is complete. Further map changes are much faster – only 20s! You can revert your vehicle to the factory OEM flash at any point, and no initial backup is necessary
