Comprehensive Features of the MHD N54 Maps Pack
The Super Licence within the MHD N54 Maps Pack encompasses a range of powerful functionalities, giving you complete control over your N54 engine’s performance and behavior.
Flasher License: The Foundation of Your N54 Tune
At the heart of the MHD N54 Maps Pack is the Flasher License. This essential component unlocks the core flashing capabilities of MHD, allowing you to load MHD OTS (Off-The-Shelf) maps, JB4 backend maps, and even custom-tailored maps to your ECU.
Features Included in the Flasher License:
- Stage 0 Stock Power: Even without opting for performance maps immediately, the Flasher License provides Stage 0, essentially a stock power tune with the foundation for further enhancements.
- Engine Diagnostics: Read and clear engine fault codes and reset adaptations, crucial for maintenance and troubleshooting.
Available Flash Options – Customize Your Driving Experience:
The MHD N54 Maps Pack goes beyond just performance increases, offering a suite of customizable flash options to fine-tune your driving experience:
- Exhaust Burble Adjustments: Control the intensity and duration of exhaust burbles, including sport mode activation, aggressiveness levels, and minimum RPM thresholds.
- Kick-Down Deactivation: Disable the kick-down feature for more precise throttle control in certain driving situations.
- Cold Start Noise Reduction: Minimize the often loud cold start sequence for a more refined sound profile.
- Variable Coolant Targets: Optimize engine coolant temperatures for different driving conditions or performance needs.
- MT Shift Bog Fix: Address the shift bog issue common in manual transmission N54 models for smoother gear changes.
- Wastegate Rattle Fix: Implement strategies to mitigate the annoying wastegate rattle prevalent in some N54 turbos.
- Top Speed Limiter (Vmax) Removal: Unleash the full potential of your N54 by removing the factory top speed limiter.
- Linear Throttle Mapping: Achieve a more direct and predictable throttle response.
- Limit Power Per Gear: Manage power delivery in individual gears to optimize traction and control.
- Individual Minimum Idle RPM: Fine-tune idle RPM settings to your preference.
- Support for Aftermarket Parts: Maps are designed to accommodate a range of aftermarket modifications.

Monitor License: Keep a Close Eye on Your Engine’s Health
The Monitor License, another key component of the MHD N54 Maps Pack, provides you with real-time insight into your engine’s operation. Utilize a customizable gauge layout with up to 8 gauges displaying over 50 engine parameters. This allows you to monitor critical data points and ensure your N54 is running optimally. Background logging is always active, and you can initiate dedicated logging sessions to save data in a standard CSV format for in-depth analysis using the built-in log viewer. For advanced users, free log analysis services are often available from MHD and the tuning community.
Key Monitoring Parameters Include:
Boost Pressure (Actual & Target), Air-Fuel Ratio (Lambda/AFR), Intake Air Temperature (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 many more.
For advanced tuning and diagnostics, the Monitor License also exposes parameters not typically available through standard BMW interfaces, such as Timing Corrections per Cylinder, Boost Setpoint, and Active Torque Limiters (availability depends on DME software version if MHD is not flashed).
All MHD OTS Maps by Wedge Performance: Dyno-Proven Performance
The MHD N54 Maps Pack includes a comprehensive selection of Off-The-Shelf (OTS) maps developed by Wedge Performance. These maps are specifically designed for the N54 engine and cater to various modification levels and fuel octane ratings. Extensive road and dyno testing ensures that these maps deliver reliable and impressive performance gains right out of the box.
MHD OTS Map Stages:
- Stage 1 (up to 360HP/520NM): Designed for stock cars, available in 91oct/95ron, 93oct/98ron, and 95oct/102ron octane versions.
- Stage 1+ (up to 390HP/600NM): For cars with recommended FMIC (Front Mount Intercooler), available in the same octane variants as Stage 1.
- Stage 2 (up to 380HP/560NM): Optimized for cars with high-flow downpipes, available in 91oct/95ron, 93oct/98ron, and 95oct/102ron octane versions.
- Stage 2+ (up to 420HP/650NM): For vehicles with high-flow downpipes and FMIC, available in the same octane variants.
- Ethanol Mix Maps: Stage 1, 1+, 2, and 2+ E30+ maps designed for ethanol blends of 30% or higher, offering even greater performance potential.
Flexfuel and MBoost: Advanced Tuning Capabilities
For those seeking the ultimate in customization and performance, the MHD N54 Maps Pack supports advanced features like Flexfuel and MBoost.
- Flexfuel: Enables true flex-fuel conversion (requires MOTIV N54 hardware flex fuel kit) allowing your car to automatically adjust to varying ethanol content in the fuel.
- MBoost Software: Necessary for custom tunes targeting boost levels beyond 18PSI, whether through increased boost ceilings or custom TMAP conversions. This is essential for maximizing performance in highly modified N54 engines.
