Experience the Power of MHD Flasher at Your Fingertips

The beauty of the MHD N55 Maps Pack lies in its user-friendly approach. You can initiate the complete tuning process from the comfort of your own garage. Simply download the MHD Flasher F+G Series application on your Apple iOS or Android device. Connecting via the MHD Wireless Adapter to your vehicle’s OBD-II port, the app guides you through a seamless installation. The initial setup is remarkably quick, taking just around 5 minutes. Subsequent map alterations are even faster, completing in a mere 30 seconds. Furthermore, reverting your BMW back to its factory OEM flash is easily achievable at any time, and no initial backup is required, granting you complete control and peace of mind.

Super Licence: Your All-Inclusive Tuning Solution

The Super Licence unlocks the full spectrum of MHD N55 Maps Pack functionalities, consolidating essential tuning capabilities into one powerful package:

Flasher License: The Foundation of Your N55 Tuning Journey

The Flasher License forms the cornerstone of your tuning experience, granting you the ability to flash your DME with MHD OTS (Off-The-Shelf) maps, JB4 backend maps, and custom-tailored maps. Key features include:

1. Unmatched Flash Speed: Utilizing the MHD WIFI Adapter, experience the quickest flash times available – a rapid 5-minute initial flash and lightning-fast 30-second map switching.
2. Stage 0 Stock Power: Start with a Stage 0 map to maintain stock power levels while enabling all flash options for future upgrades.
3. Comprehensive Diagnostics: Read and clear engine trouble codes and reset adaptations, ensuring your engine is running optimally.

Available flash options expand your control over your N55 engine:

• Exhaust Burble Customization: Fine-tune exhaust burbles with adjustable duration, sport mode activation, aggressiveness, minimum speed, and RPM parameters.
• Startup Roar Control: Manage the intensity of your engine’s startup roar.
• Cold Start Noise Reduction: Minimize cold start noise for a more discreet operation.
• Exhaust Flap Management: Set the exhaust flap to remain permanently open in sport mode for enhanced sound.
• Top Speed Limiter Removal (Vmax): Eliminate the factory top speed limiter for unrestricted performance on closed courses.
• Sport/Racing Cooling Mode: Activate enhanced coolant management for demanding driving scenarios.
• Limit Power per Gear: Customize power delivery based on gear selection for optimized traction and control.
• XDI HPFP Support: Compatibility with XDI High Pressure Fuel Pumps for higher performance fuel delivery.
• Catalytic Converter Delete (Cat Delete): Options for off-road use configurations.

MHD+: Advanced Features for the Discerning Tuner

The MHD+ feature unlocks a realm of advanced customization and control over your N55 engine, featuring:

1. 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 intuitive interface also lets you create valet maps or lower-power maps for cruising by reducing power output in 5% increments, down to 50% of the map’s potential.
2. Antilag System: Engage antilag to rapidly build boost while stationary, then launch with maximum power. Activating antilag is simple: hold the cruise control RES button and apply full throttle. The system intelligently calibrates the engine to build boost quickly. Release the button, and you’re ready to accelerate. Safety parameters, including coolant temperature, EGT, and usage limits, are pre-set for safe operation with OTS maps, and boost targets are adjustable.
3. Switchable Burble per Map Slot: Customize burble aggressiveness and duration independently for each map slot, enabling on-the-fly burble adjustments using the MHD+ Map Switch feature.
4. On-The-Fly Exhaust Flap Control: Take command of your exhaust flap via the MHD+ Live Menu, choosing between always open, always closed (with high-load override), or OEM operation.
5. Ethanol Content Monitoring: Real-time ethanol content display via the MHD+ Live Menu when using a compatible Ethanol Content Analyzer.
6. Motiv ReFlex Controller Integration: Full two-way CANBUS integration with the Motiv ReFlex controller, enabling advanced features like DME limp mode for Port Injection (PI) injector errors and DME control of external wastegates.
7. Overrun “Brap” Noise: Emulate the distinctive “brap” sound of M-cars during throttle lift-off after acceleration.
8. 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 engagement is still required). NLS delivers quicker shifts, maintains boost between gears, and eliminates “shift bog,” even on high-power setups with Port Injection.
9. PI Safety (Coil Cut): An advanced safety feature that prevents lean cylinder conditions caused by DME cylinder injection cuts. By also cutting coil firing to the affected cylinder, it prevents potentially damaging lean mixtures when the DME reduces injection due to misfires or during clutch-in shifts. This, combined with ReFlex integration, makes MHD a leading safe platform for supplemental port injection.

Monitor License: Keep a Close Watch on Your Engine’s Performance

The Monitor License provides real-time insights into your engine’s behavior, ensuring optimal performance and health. Utilize a customizable gauge layout with up to 8 fully adjustable gauges to monitor over 50 engine parameters at a glance. Background logging saves data to standard CSV files for in-depth analysis using the integrated log viewer. Free log analysis services are also often available for further support.

Key parameters you can monitor include: 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) pressure, Throttle Position, Wastegate Duty Cycle (WGDC), RPM, Speed, Exhaust Gas Temperature (EGT), and more. Advanced parameters, not typically exposed by BMW, such as Timing Corrections per Cylinder and Boost Setpoint, are also accessible for detailed monitoring and tuning adjustments (depending on DME software version and flash status).
