What you need
Flashing requires MHD Flasher, MG Flasher or BootMod3. They write the tune through the OBD port and record the datalogs a well-running tune depends on.
Flex Fuel tunes and steering-wheel map switching work with MHD and BootMod3. Some cars with the latest BMW software need a DME bench unlock before OBD flashing.
