Diving Deeper into the MHD N55 Maps Pack

The MHD N55 Maps Pack is accessed through the Super Licence, unlocking a range of functionalities designed to cater to every N55 owner, from those seeking a mild performance bump to enthusiasts craving maximum power. This Super Licence includes:

Flasher License: This is your gateway to flashing your DME (Digital Motor Electronics) with MHD maps. Whether you opt for MHD OTS (Off-The-Shelf) maps, JB4 backend maps, or custom tunes, the Flasher License is essential. Key features include:

1. Unmatched Flashing Speed: Utilizing the MHD WIFI Adapter, initial flashes take just 5 minutes, and map switching is a mere 30 seconds. This speed minimizes downtime and gets you back on the road, enjoying enhanced performance, faster.
2. Stage 0 Stock Power: Want to explore flash options without immediately increasing power? Stage 0 provides a stock power level base, allowing you to add other flash options and customize your driving experience incrementally.
3. Engine Diagnostics and Maintenance: Beyond performance, the Flasher License enables you to read and clear engine codes and reset adaptations. This diagnostic capability is invaluable for maintaining your N55 engine’s health and addressing any issues promptly.

Available Flash Options within the Maps Pack:

The MHD N55 Maps Pack offers a wide array of customizable flash options, allowing you to fine-tune your driving experience to your exact preferences:

• Exhaust Burble Adjustment: Control the intensity and duration of exhaust burbles, with settings for sport mode, aggressiveness, minimum speed, and RPM. Personalize your car’s sound profile to match your style.
• Startup Roar and Cold Start Noise Reduction: Command attention with an aggressive startup roar or choose to reduce cold start noise for a more subtle neighborhood presence.
• Exhaust Flap Control: Keep the exhaust flap always open in sport mode for a consistently aggressive sound, maximizing auditory feedback during spirited driving.
• Top Speed Limiter Removal (Vmax): Unleash the full potential of your BMW on the track or Autobahn by removing the factory top speed limiter. (Note: check local regulations).
• Sport/Racing Cooling Mode: Optimize coolant temperatures for demanding driving conditions, crucial for track days or hot climates.
• Limit Power per Gear: Fine-tune power delivery in each gear, enhancing traction and control, especially beneficial for RWD models.
• XDI HPFP Support: Compatibility with XDI High-Pressure Fuel Pumps, essential for higher-stage maps and maximizing performance with ethanol blends.
• Catalytic Converter Delete (Cat Delete): For off-road use, options to accommodate decatted downpipes, further improving exhaust flow and power.

MHD+ Features: Stepping up to MHD+ unlocks advanced custom coding, taking your N55 tuning to the next level with features like:

1. On-the-Fly Map Switching: Seamlessly switch between up to four map slots within the same stage. This is incredibly useful for adapting to varying fuel qualities (e.g., switching between pump gas and ethanol blends like E30) or adjusting power levels on the go. The power slider allows you to reduce output from 100% down to 50% in 5% increments, perfect for creating a valet mode or a more relaxed cruising map.
2. Antilag System: Experience rapid boost building for quicker launches. By holding the cruise control ‘RES’ button and applying heavy throttle, the system pre-spools the turbo. Release the button, and you’re propelled forward with minimal lag. Safety parameters are built-in to protect your engine.
3. Switchable Burble per Map Slot: Customize burble aggressiveness and duration for each map slot. Enjoy different sound profiles depending on your selected map and driving mood.
4. On-The-Fly Exhaust Flap Control: Take manual control of your exhaust flap via the MHD+ Live Menu. Choose always open, always closed (opens under high load), or OEM operation for personalized sound management.
5. Ethanol Content Quick View: If equipped with a compatible ethanol content analyzer, monitor ethanol percentage in real-time via the MHD+ Live Menu, crucial for running ethanol blend maps accurately.
6. Motiv ReFlex Controller Integration: Full integration with the Motiv ReFlex controller via CANBUS allows for advanced features like DME limp mode for Port Injection errors and DME control of external wastegates, enhancing safety and control for advanced setups.
7. Overrun Brap Noise: Emulate the distinctive “brap” sound of M-cars when releasing the throttle after acceleration, adding an extra layer of auditory excitement.
8. No Lift Shift (NLS) for Manual Cars: For manual transmission BMWs, NLS allows for wide-open throttle shifting without lifting off the accelerator. This results in faster shifts, maintained boost pressure, and eliminates “shift bog,” ideal for performance driving.
9. Port Injection (PI) Safety (Coil Cut): A crucial safety feature, especially for cars running supplemental port injection. It prevents lean cylinder conditions by cutting ignition to cylinders where the DME has cut fuel injection (due to misfires, shifting, etc.), ensuring a safer tuning environment, particularly at higher power levels.

Monitor License: Keep a close eye on your engine’s vitals with a customizable gauge layout displaying up to 8 parameters simultaneously. Choose from over 50 engine parameters, including boost, AFR, IAT, timing, temperatures, and more. Background data logging saves data to CSV files for in-depth analysis using the built-in log viewer, and MHD offers free log analysis support. Advanced parameters like timing corrections and boost setpoint are also available for detailed monitoring and tuning optimization.
