The Power of the Flasher License
At its core, the Flasher License unlocks the ability to flash your DME with MHD software. This includes accessing a library of MHD OTS (Off-The-Shelf) maps, JB4 backend maps, and even custom-tailored maps designed for your specific modifications.
Key Features of the Flasher License:
- Unmatched Flashing Speed: Utilizing the MHD WIFI Adapter, experience the quickest flash times on the market. Initial flashes take only 3.5 minutes, while map switching is completed in a lightning-fast 20 seconds.
- Stage 0 Stock Power and Beyond: The Flasher License provides a foundation for various tuning options, starting with Stage 0 for stock power and allowing for the addition of further flash options to increase performance.
- Comprehensive Diagnostic Tools: Read and delete engine codes and reset adaptions directly through the MHD app, empowering you with essential diagnostic capabilities.
Available Flash Options for Customization:
- Exhaust Burble Adjustment: Fine-tune your exhaust burble with customizable parameters such as duration, aggressiveness, and activation speed/RPM in sport mode.
- Cold Start Noise Reduction: Minimize unwanted noise during cold starts for a more refined driving experience.
- Exhaust Flap Control: Set your exhaust flap to remain always open in sport mode, maximizing auditory feedback.
- Shift Brap (G8x Specific): Experience aggressive shift sounds specifically engineered for G8x models.
- Top Speed Limiter Removal (Vmax): Eliminate the factory top speed limiter to fully explore your BMW’s performance capabilities on closed courses.
- OEM/Aftermarket Downpipe Compatibility: Optimize your tune for both OEM and aftermarket downpipes, and many more customizable options to suit your modifications.
Unleashing Advanced Features with MHD+ Custom Code
The MHD+ custom code takes your tuning experience to the next level, unlocking a suite of advanced features designed for performance enthusiasts:
- On-the-Fly Map Switching: Seamlessly switch between up to four map slots within the same stage. This allows for real-time adjustments based on fuel quality (e.g., switching between pump gas and ethanol blends like E30) or desired power levels. The power output can be adjusted in 5% increments, down to 60%, allowing for custom valet or reduced-power maps.
- Antilag System: Engage antilag to rapidly build boost while stationary, enabling explosive launches. Activated by holding the cruise control speed down button and applying full throttle, the system builds boost in seconds, even with larger turbos. Comprehensive safety measures are integrated, monitoring coolant temp, EGT, and usage duration. Adjustable boost targets are available for OTS users.
- Switchable Burble per Map Slot: Customize exhaust burble settings for each map slot. Enjoy different burble profiles on-the-fly with MHD+ Map Switching, tailoring the auditory experience to your driving style.
- On-The-Fly Exhaust Flap Control: Take manual control of your exhaust flap through the MHD+ Live Menu. Choose between always open, always closed (opens under high load), or OEM operation for complete exhaust sound management.
- Ethanol Content Quick View: Monitor ethanol content directly through the MHD+ Live Menu when using a compatible Ethanol Content Analyzer.
- Advanced Motiv ReFlex Integration: Experience seamless 2-way CANBUS integration with Motiv ReFlex, enabling advanced functionalities like DME limp mode for PI injector errors, DME control of external wastegates, and comprehensive control over supplemental port injection and auxiliary outputs. This simplifies custom tuning by allowing all adjustments within the DME after a one-time ReFlex firmware flash.
- Cold Start Noise Reduction per Map Slot: Customize cold start noise reduction settings for each individual map slot, providing granular control over engine sound profiles.
- No Lift Shift: Execute rapid gear changes without lifting off the throttle in 6MT cars, maximizing acceleration and shift speed.
- Custom TCU Limiter Removal: Eliminate TCU limiters while preserving all OEM safety features and Launch Control functionality.
- KnockCEL: For custom tunes, the KnockCEL feature provides a visual warning (blinking CEL) if timing corrections reach a tuner-defined threshold, aiding in performance monitoring and safety.
- MHD MaxCool: Activate a specialized cooling mode to dramatically reduce oil and coolant temperatures, combating heat soak during demanding situations like staging at a track. MaxCool lowers coolant target temperatures, activates the electric fan and thermostat, and engages high water pump cooling mode. Activated via the MHD+ Live Adjust menu, it remains active until manually deactivated or the engine is turned off.
- MHD Real-Time Tuning: Experience revolutionary real-time tuning capabilities, a world-first for modern BMWs. Custom tuners can edit major engine parameters, including map switch and flex fuel settings, live while the engine is running. Real-time tuning for additional tables, including Advanced ReFlex PI control, is continuously being added.
Comprehensive Engine Monitoring with the Monitor License
The Monitor License transforms your mobile device into a powerful digital gauge cluster, providing real-time insights into your engine’s performance. Monitor over 50 engine parameters with a customizable gauge layout featuring up to 8 fully adjustable gauges. Parameters include boost, AFR, IAT, timing per cylinder, temperatures, pressures, throttle position, WGDC, RPM, speed, EGT, and more. Background logging saves data in CSV format for detailed analysis using the built-in log viewer, and free log analysis services are often available. Advanced parameters like timing corrections per cylinder and boost setpoint are also accessible, depending on DME software version and MHD flash status.
Access to a Wide Range of MHD OTS Maps
The MHD Flasher License grants access to a comprehensive selection of MHD OTS maps specifically engineered for the S58 engine. These maps are designed for various modification levels and octane ratings and have undergone extensive road and dyno testing for reliability and performance.
- Stage 1 Maps (up to 670HP/800NM): Available in 91oct/95ron, 93oct/98ron, and 95oct/102ron for stock cars and vehicles equipped with gasoline particulate filters.
- Stage 2 Maps (up to 720HP/850NM): Available in 91oct/95ron, 93oct/98ron, and 95oct/102ron for vehicles with high-flow downpipes and without gasoline particulate filters.
- Ethanol Mix Maps (up to 750HP / 880NM): Stage 1 & 2 E30-40 Maps designed for ethanol blends of 30-40%.

*Vehicles with the latest BMW software may require a DME bench unlock for OBD flashing, regardless of production date. Cars produced after 06/2020 can only be tuned with a special FEMTO unlock, necessitating DME submission to FEMTO in Finland. MHD automatically detects the FEMTO unlock after this procedure. Flashing back to stock will remove the FEMTO unlock, requiring a re-unlock for future MHD flashing.*
