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 unrivaled drivability.
The Super Licence provides all the available MHD functionalities in one package (all single licenses are included, Flasher, Monitor and all 3 Map packs!):
- Flasher License:
The Flasher License unlocks the ability to flash with MHD (MHD OTS maps, JB4 backend maps and custom maps)
Available flash options:- Exhaust burble (Duration base and sport mode, aggressiveness, min. speed, min. rpm)
- Startup roar
- Cold start noise reduction- Exhaust flap always open in sport mode
- Top speed limiter (Vmax) removal
- Sport / Racing Cooling mode for coolant
- Limit Power per Gear
- Support for XDI HPFP
- 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!
4. On The Fly Exhaust Flap Control: You can now control you exhaust flap how you like, always open, always closed (it will open at high load) or OEM operation via MHD+ Live Menu.
5. Ethanol Content Quick View: You can now see the Ethanol content via MHD+ Live Menu if a compatible Ethanol Content Analyzer is installed.
6. Full and native integration with the Motiv ReFlex controller: We have 2-way CANBUS integration to allow advanced capabilities such as the DME limp when there is a PI injector error and DME control of external wastegates
7. Overrun Brap Noise: You can now enjoy the special "brap" noise M-cars make when letting of the throttle after accelerating.
8. No Lift Shift for Manual Cars: This allows manual transmission vehicles to WOT shift without having to lift their foot off of the accelerator pedal (you must still depress the clutch). Using NLS, 6MT drivers can experience the quickest shifts while carrying more boost to the next gear. Shifting with NLS also completely removes the "shift bog" some would experience when traditionally WOT shifting quickly. This feature is also 100% safe to use on big power cars / cars running Port Injection thanks to our next feature...
9. PI Safety (coil cut): We introduced this unique feature on N54 vehicles some years ago, and are happy to bring it to more platforms. It prevents lean cylinder issues when the DME cuts injection to individual cylinders by also preventing that cylinder's coil from firing. The DME cuts injection for misfires, while clutch-in shifting, etc which could leave an extremely lean mixture of only the PI share of fuel being ignited. With our ReFlex integration, we already had a safety in the form of a limp mode when a PI injector error was reported, but this brings the safety to the next level, making MHD by far the safest platform to run supplemental port injection!
