The initial setup is remarkably quick, taking just around 5 minutes. Subsequent map changes are even faster, clocking in at a mere 30 seconds! And if you ever wish to return your vehicle to its stock settings, reverting to the factory OEM flash is simple and doesn’t require an initial backup.
The Super License is the key to unlocking the full spectrum of MHD functionalities, bundling everything you need into a single, powerful package:
Comprehensive Features of the MHD Super License
The MHD Super License is not just a single feature; it’s a suite of powerful tools designed to give you complete control over your N55 engine’s performance and behavior. Let’s delve into the core components of this license:
Flasher License: The Foundation of Your N55 Tuning
The Flasher License is the essential starting point, granting you the ability to flash your DME with MHD maps. This includes MHD’s expertly crafted Off-The-Shelf (OTS) maps, JB4 backend maps, and even custom maps tailored to your specific needs.

Key Features of the Flasher License:
- Unrivaled Flash Speed: Utilizing the MHD WIFI Adapter, experience the fastest flash times in the market. Initial flashes take approximately 5 minutes, while map switching is lightning-fast at just 30 seconds.
- Stage 0 Stock Power: The Flasher License includes Stage 0 maps, allowing you to retain stock power levels while benefiting from the flash functionalities and the option to add further flash options.
- Diagnostic and Maintenance Tools: Read and delete engine codes and perform adaptations resets directly through the MHD app, empowering you to maintain your N55 engine effectively.
Available Flash Options to Customize Your Drive:
- Exhaust Burble Control: Fine-tune your exhaust burble with adjustable duration, aggressiveness, minimum speed, and RPM settings, customizable for both drive and sport modes.
- Startup Roar and Cold Start Noise Reduction: Control your engine’s initial roar upon startup and reduce cold start noise for a more refined experience.
- Exhaust Flap Control: Keep your exhaust flap permanently open in sport mode for enhanced sound and performance.
- Top Speed Limiter (Vmax) Removal: Break free from factory speed limitations and explore your N55’s true top-end potential (where legally permitted).
- Sport/Racing Cooling Mode: Activate enhanced cooling modes for coolant to optimize performance during demanding driving conditions.
- Limit Power per Gear: Gain granular control over power delivery by limiting power output in specific gears.
- XDI HPFP Support: Seamlessly integrate and optimize performance with upgraded High-Pressure Fuel Pumps (HPFP) from XDI.
- Catalytic Converter Delete (Cat Delete): Accommodate modifications like catalytic converter removal for off-road or track use (compliance with local regulations is the user’s responsibility).
MHD+: Advanced Customization and Control
The MHD+ feature expands your tuning capabilities with advanced custom coding, offering a new level of control and personalization for your N55 engine.
MHD+ Unlocks Powerful Features:
- On-the-Fly Map Switching: Store up to four different maps within the same stage and switch between them instantly. This is invaluable for adapting to varying fuel qualities (like switching between pump gas and ethanol blends like E30) or adjusting power levels on the go. The system also accommodates flex fuel setups, allowing for pump gas map selections based on fuel quality at each refill.
- Adjustable Power Levels: Beyond octane adjustments, fine-tune the power output of each map slot using a slider. Reduce power in 5% increments, down to 50%, creating custom valet maps or lower-power cruising modes.
- Antilag System: Experience rapid boost building with the integrated antilag system. By holding the cruise control RES button and applying heavy throttle, the system pre-spools the turbo, allowing for near-instantaneous power delivery when you release the button. Safety parameters like coolant temp, EGT temp, and cooldown times are pre-set for safe operation using OTS antilag maps, with adjustable boost targets available.
- Switchable Burble per Map Slot: Customize exhaust burbles for each map slot. Set your primary Map 1 burble and then adjust the aggressiveness and duration for the other map slots, allowing for on-the-fly burble profile changes with MHD+ Map Switching.
- On-The-Fly Exhaust Flap Control: Take direct control of your exhaust flap through the MHD+ Live Menu. Choose between always open, always closed (opens under high load for safety), or OEM operation.
- Ethanol Content Quick View: Monitor ethanol content in real-time via the MHD+ Live Menu when using a compatible Ethanol Content Analyzer.
- Motiv ReFlex Controller Integration: Full and native two-way CANBUS integration with the Motiv ReFlex controller enables advanced features like DME limp mode for PI injector errors and DME control of external wastegates.
- Overrun Brap Noise: Emulate the distinctive “brap” noise of M-cars during throttle lift-off after acceleration.
- No Lift Shift (NLS) for Manual Cars: For manual transmission vehicles, NLS allows for wide-open throttle (WOT) shifting without lifting off the accelerator pedal (clutch use is still required). NLS enables faster shifts, maintains boost between gears, and eliminates “shift bog,” even on high-power, port-injected N55s.
- Port Injection (PI) Safety (Coil Cut): Building on MHD’s legacy of safety features, PI Safety prevents lean cylinder conditions that can occur when the DME cuts fuel injection to individual cylinders (for misfires or during clutch-in shifting). The system also prevents the corresponding cylinder’s coil from firing, ensuring a safer and more robust supplemental port injection setup.
Monitor License: Keep a Close Watch on Your Engine’s Health
The Monitor License transforms your mobile device into a comprehensive gauge display and data logging tool. Monitor your N55 engine’s performance in real-time with customizable gauge layouts, displaying up to 8 parameters simultaneously. Choose from over 50 engine parameters, all while background logging captures data for later analysis.

- Extensive Parameter List: Monitor critical parameters including Boost, Boost Target, Lambda (AFR), Intake Air Temp (IAT), Ignition Timing per Cylinder, Coolant Temperature, Oil Temperature, Oil Pressure, Transmission Temperature, HPFP, Throttle Position, Wastegate Duty Cycle (WGDC), RPM, Speed, EGT, and more.
- Advanced Parameters: Access advanced parameters not typically exposed by BMW (depending on DME software version and flash status) such as Timing Corrections per Cylinder, Boost setpoint, and Active torque limiters for in-depth tuning and diagnostics.
- Data Logging and Analysis: Activate logging mode to save data to a standard CSV file for detailed analysis using the built-in log viewer. MHD also offers free log analysis support to help you interpret your engine data.
