MHD Super Tuning License — N55 (F-Series)

MHD is the most widely used N55 tuning platform, and the Super Tuning License for the N55 (F-Series) unlocks the full suite: off-the-shelf Stage 1, Stage 2 and Stage 2+ FlexFuel maps, custom-tune support, and full data-logging — flashed over the air from the MHD phone app. The FlexFuel maps (paired with the CAN FlexFuel Analyzer) read live ethanol content and adjust fuelling, timing and boost for whatever's in the tank. This is the F-Series license; E-chassis N55 cars (E82/E9x) require a different product. The license is sold through the MHD web store; flashing needs a supported OBD cable.
