MHD Flash Tune for BMWs and Toyota Supra

MHD Flasher is the first android and iOS Handheld Application to bring ECU Tuning and Monitoring to BMW N54, N55, S55, B58, S58,S63 and N13 Engine. The MHD Flasher Reveals the immense margin of power BMW Left on the Table with the N54, N55, S55, B58, S58, S63 and N13 Motor, while still retaining the sophistication of the original engine management program.

MHD is a full custom tuning platform for the factory engine computer (DME) available for Windows, macOS and mobile apps for iOS and Android. Users can change their tunes through the OBD port in their own driveway using the web or mobile apps taking just seconds to do so.

Our latest development includes the addition of the MHD+ CustomROM features that add advanced end user and tuning features such as:

  • Map Switching On-The-Fly using steering wheel cruise control buttons. Flash the vehicle once and have access to 4 switchable maps on the steering wheel changing the calibration entirely from one map slot to the next
  • Flex Fuel Tuning - Tune for any Ethanol blend by having a Flex Fuel sensor report Ethanol % to the engine control unit (DME) and have it manage the tune from regular petrol (0% Ethanol) to 100%, without re-flashing
  • AntiLag - Build boost while stationary or rolling by using steering wheel cruise button press and the Accelerator pedal allowing for insta-boost when roll racing or launching
  • New Map Editor - advanced tuning editor with close to 5000 tuning tables available
  • Datalogging of over 80 advanced (RAM) channels and hundreds of others available at highest throughput of any tool available on the market today
  • Ethanol In-Dash Indicator - software changes applied to the DME to allow checking of your Ethanol content as reported by the Flex Fuel Sensor in the vehicle's dash on the RPM gauge (e.g. 2000rpm = 20% ethanol, 5500rpm = 55% ethanol)
  • Switchable Burble Per Map Slot- You can now fully setup the burble for your main Map 1 and then adjust aggressiveness and duration for all other map slots.
  • On The Fly Exhaust Flap Control- You can now control your exhaust flap to always open, always closed (it will open at high load) or OEM operation via MHD+ Live Menu.
  • Overrun Brap Noise- You can now enjoy the special "brap" noise M-cars make when letting off the throttle after accelerating.
  • KnockCEL- For custom tunes the CEL will blink if timing corrections reach a threshold set by the tuner.
  • Custom TCU Limiter Removal (GEN2 Only ATM)- Remove TCU Limiter while still retaining all safeties and OEM Launch Control
  • No Lift Shift (Gen2 Only ATM)- Shift without releasing the throttle on 6MT cars to get the quickest shifts

As an authorized dealer for MHD, we are excited to offer their products to our client-base. If you’re wondering why tune or use MHD, the easy answer is that immediate power can be achieved by flashing your BMW’s ECU (also known as DME). From the factory, BMWs are very robust and always leave power on the table to be gained through Tuning. With a simple flash tune, the entire system can make a lot more Horsepower (HP) and Torque (TQ) than the factory power levels.
