MHD Flasher version 4.89

MHD Flasher is an innovative flash tuning application designed specifically for BMW and Toyota Supra A90 vehicles. Distinct from traditional piggyback modules, it offers comprehensive DME remapping capabilities while preserving all OEM safety features. This ensures optimal performance without compromising safety or drivability.

Full OBD Flashing:
MHD allows users to initiate the tuning process from the comfort of their home. By simply downloading the MHD Flasher app and connecting it through a MHD WiFi adapter to the vehicle's OBD-II port, users can complete the initial installation in approximately five minutes. Subsequent adjustments to the maps can be executed swiftly in around 20 seconds. Notably, reverting to the factory OEM flash is possible at any time without the need for an initial backup.
