• Ease of Use: Tune your car from the comfort of your home with an intuitive mobile app and rapid flashing process.

Understanding the MHD Flasher License for B58 Engines

The core of the MHD tuning system is the Flasher License. This license is the key that unlocks the capability to flash your B58 DME with MHD software. This includes access to MHD’s Off-The-Shelf (OTS) maps, custom maps, and even JB4 backend maps, providing a wide range of tuning options to suit your specific needs and modifications.

Key features unlocked by the MHD Flasher License for B58 include:

• Fastest Flash Times: Utilizing the MHD WIFI Adapter, initial flashing takes approximately 3.5 minutes, and map switching is lightning-fast at around 19 seconds.
• Stage 0 Stock Power Option: The flasher license includes a Stage 0 map, allowing you to access basic flash functionalities without immediately increasing power. This is ideal for users who want to explore features before committing to performance stages.
• Engine Code Reading and Deletion: Diagnose and clear engine fault codes directly through the MHD app.
• Adaptations Reset: Reset engine and transmission adaptations after flashing for optimal performance and learning.

The MHD Flasher License also enables a wide array of customizable flash options, allowing you to tailor your B58 engine’s behavior to your preferences:

• Exhaust Burble Adjustment: Control the duration, aggressiveness, minimum speed, and RPM for exhaust burbles in both Drive and Sport modes.
• Startup Roar Control: Customize the intensity of the engine startup sound.
• Cold Start Noise Reduction: Reduce the volume of the cold start cycle for a quieter neighborhood.
• Exhaust Flap Control: Set the exhaust flap to remain permanently open in Sport mode for a more aggressive sound.
• Top Speed Limiter Removal (Vmax): Remove the factory speed limiter to fully explore your B58’s top-end potential (where legal and safe to do so).
• Sport/Racing Cooling Modes: Activate enhanced cooling modes for both coolant and intercooler systems to maintain optimal temperatures during spirited driving or track use.
• Support for High-Performance Fuel Pumps: Compatible with XDI HPFP & DORCH HPFP upgrades for higher horsepower builds.
• OPF/GPF and Catalytic Converter Delete Options: Options to remove Gasoline Particulate Filters (GPF/OPF) and catalytic converters for off-road use and maximum exhaust flow.

Exploring MHD+ Features: Taking Your B58 Tuning to the Next Level

For enthusiasts seeking even more advanced control and customization, the MHD+ feature unlocks a suite of special functionalities that further enhance your B58 tuning experience. MHD+ builds upon the foundation of the Flasher License, adding features like on-the-fly adjustments and performance enhancements.

MHD+ Features Include:

• On-The-Fly Map Switching: Seamlessly switch between up to four different 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. You can even create a valet map or a lower power map for cruising by reducing power output in increments of 5%, down to 60% of the map’s potential.
• Antilag System: Engage antilag to build boost pressure while stationary, enabling rapid launches. Activate antilag by holding the cruise control RES button and applying full throttle. Release the button for an immediate surge of power. Safety parameters are in place to protect your engine, and boost targets are adjustable within safe limits.
• Switchable Burble per Map Slot: Customize exhaust burble settings for each map slot. Set a specific burble configuration for your primary Map 1 and adjust aggressiveness and duration for other maps, allowing for on-the-fly burble profile changes with the MHD+ Map Switch feature.
• On-The-Fly Exhaust Flap Control: Take direct control of your exhaust flap via the MHD+ Live Menu. Choose between always open, always closed (opens under high load), or OEM operation for customized sound profiles.
• Ethanol Content Quick View: If you have a compatible Ethanol Content Analyzer installed, monitor ethanol content directly through the MHD+ Live Menu for precise ethanol blend management.
• Full Integration with Motiv ReFlex Controller: Native two-way CANBUS integration with the Motiv ReFlex controller unlocks advanced capabilities like DME limp mode in case of Port Injection (PI) injector errors and DME control of external wastegates for sophisticated fuel and boost management.
• Overrun Brap Noise: Enjoy the distinctive “brap” sound characteristic of M-cars when releasing the throttle after acceleration, adding an extra layer of auditory excitement.

The Monitor License: Keep a Close Eye on Your B58’s Health

Alongside performance tuning, monitoring your engine’s health is crucial, especially after increasing power output. The MHD Monitor License provides a comprehensive suite of real-time gauges and logging capabilities to ensure your B58 engine is running optimally.

The Monitor License features:

• Configurable Real-Time Gauges: Display up to 8 customizable gauges simultaneously, choosing from over 50 engine parameters. Monitor critical data like boost pressure, target boost, 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 more.
• Background Data Logging: Continuously log engine parameters in the background, even while monitoring gauges.
• Log Analysis Tools: Save data logs in standard CSV format for detailed analysis using the built-in log viewer. MHD also offers free log analysis services to help you interpret your data and optimize your tune.
• Advanced Parameters: Access advanced engine parameters not typically exposed by BMW for even finer monitoring and tuning adjustments (availability depends on DME software version if MHD is not flashed), including timing corrections per cylinder, boost setpoint, and active torque limiters.
