The MHD Flasher F+G Series is a complete flash tuning app for your BMW. 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 unrivalled drivability.

You can install MHD right at home and start tuning immediately! Simply download the MHD Flasher F+G Series app that connects via our MHD Wireless Adapter to your Apple iOS or Android device and your vehicle’s OBD-II port, start the app, and within 5 minutes the initial installation is complete. Further map changes are much faster – only 30 seconds! You can revert your vehicle to the factory OEM flash at any point, and no initial backup is necessary.

The Super Licence provides all the available MHD functionalities in one package:

• Flasher License: 
  
  The Flasher License unlocks the ability to flash with MHD (MHD OTS maps, JB4 backend maps and custom maps) 
  
  Features: 
  1. Quickest flash times on market with our MHD WIFI Adapter (3.5 min initial, 19 sec map switch) 
  2. CS / GTS style engine maps maps included 
  3. CS / GTS style transmission flash included
  3. Stage 0 stock power (all flash options can be added)
  4. Reading / Deleting Engines Codes + Adaptions Reset
  
  Available flash options: 
  - Exhaust burble (Duration base and sport mode, aggressiveness, min/max. speed, min/max. rpm) 
  - Startup roar
  - Cold start noise reduction 
  - Exhaust flap always open in sport mode 
  - Top speed limiter (Vmax) removal 
  - Limit power per gear in percent (1st - 5th gear)
  - Adjustable rev matching for 6MT (eco, sport, sport plus)
  - Support for precision race works coils

• MHD+: 
  The MHD+ Feature unlocks our special custom code. 
  

  
  1. On the Fly Map Switching: You can select 4 slots for the same stage to adjust fuel quality on the fly (pump gas and fixed ethanol like E30 map) as well as a power level in percent per map slot. If the flex fuel option is activated (and the required hardware installed) you can still setup 4 pump gas maps in order to quickly setup and change to the pump gas quality that is used at the time when the car is refilled without ethanol.

  In addition to the octane selections, you can also use the slider to reduce the power that each map will make. This is very useful if you would like to make your own valet map or lower power map for cruising. The power can be reduced from 100% all the way down to 50% in 5% increments, this means if you put 50% into one map slot than this map only has half the power available it would usually make.
  
  2. Antilag: Allows you to quickly build a set amount of boost while limiting acceleration, then quickly take off once released. To activate antilag, press and hold the cruise control RES button on your steering wheel and apply heavy throttle. Our antilag strategy will adjust the engine calibration to build boost. Once boost is built, release the button and go! The time required to reach boost target will vary depending on your turbo, but even large upgraded turbos are able to hit high boost within 1-2 seconds!
  
  There are also various safeties in place such as coolant temp, EGT temp, max duration per use, and cooldown time between uses. These values, as well as the time delay after button press until antilag activates are all set to safe values for those using the OTS antilag flash option. OTS users will have the ability to adjust the antilag boost target (max value depends on engine).
  

  
  

  3. 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. This means you can now enjoy on the fly burble changes with our MHD+ Map Switch feature!

• Monitor License:
  Monitor your engine behavior to make sure it is running perfectly using a configurable and very responsive gauge layout with up to 8 fully adjustable gauges. 50+ engine parameters are available at a glance and are logged in the background! Activate the logging mode to save the data to a standard CSV file for later analysis using the built in log viewer. Additionally, we will happily provide free logs analysis.
  
  These are some of the available monitors: Boost, Boost Target, Lambda (AFR), Intake Air Temp (IAT), Ignition Timing per Cylinder, Coolant Temperature, Oil Temperature, Oil Pressure, Transmission Temperature, High Pressure Fuel Pump (HPFP), Throttle Position, Wastegate Duty-Cycle (WGDC), RPM, Speed, EGT etc.
  
  
  Advanced parameters that are not exposed by BMW are available for fine monitoring and tuning (depending on the DME software version if MHD is not flashed) like Timing Corrections per Cylinder, Boost setpoint, Active torque limiter etc.
