MHD+ Custom Code: Elevating Your Tuning Experience
Going beyond basic flashing, MHD+ custom code unlocks a suite of advanced features designed for enthusiasts who demand the ultimate level of control and customization.
-
On-the-Fly Map Switching: Seamlessly switch between up to four different map slots within the same tuning 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 system also includes a power level slider, allowing you to reduce power output from 100% down to 60% in 5% increments, perfect for valet mode or less aggressive driving scenarios.
-
Antilag System: Experience rapid boost building for enhanced launch performance. By holding the cruise control speed down button and applying full throttle, the system pre-spools the turbo. Release the button for immediate acceleration with minimal lag. Safety parameters are built-in, monitoring coolant temperature, EGT, and usage limits to ensure engine protection. Boost target is adjustable for OTS maps (engine dependent).
-
Switchable Burble per Map Slot: Customize exhaust burbles uniquely for each map slot. Set an aggressive burble for your primary performance map and milder or no burbles for other slots, giving you on-the-fly sound profile changes.
-
On-The-Fly Exhaust Flap Control: Take direct control of your exhaust flap via the MHD+ Live Menu. Choose between always open, always closed (with load-based opening), or OEM operation for complete sound management.
-
Ethanol Content Quick View: If you have a compatible ethanol content analyzer installed, the MHD+ Live Menu provides a real-time display of ethanol content, crucial for accurate ethanol blend tuning.
-
Advanced Motiv ReFlex Integration: Deep two-way CANBUS integration with Motiv ReFlex systems provides advanced capabilities, such as DME-driven limp mode for port injection errors, DME control of external wastegates, and comprehensive management of supplemental port injection and auxiliary outputs (WGDC, extra fuel pumps, nitrous, etc.). Simplify custom tuning by flashing the ReFlex firmware once to the MHD+ compatible version and managing all further tuning adjustments directly within the DME.
-
Cold Start Control per Map Slot: Individually configure cold start noise reduction for each map slot, offering granular control over startup sound profiles in different tuning configurations.
-
No Lift Shift: For 6-speed manual transmission cars, maintain full throttle during gear changes for faster, smoother shifts.
-
Custom TCU Limiter Removal: Remove torque limiters within the Transmission Control Unit (TCU) while retaining all OEM safety features and Launch Control functionality, maximizing performance potential for tuned vehicles.
-
KnockCEL: A valuable tool for custom tuners, KnockCEL allows the check engine light (CEL) to blink when timing corrections reach a pre-defined threshold set by the tuner, providing a visual warning of potential knock events.
-
MHD MaxCool: Activate a specialized cooling mode to aggressively reduce oil and coolant temperatures, and lower intake air temperatures (IAT) at standstill. This feature combats heat soak, particularly beneficial in demanding situations like staging lanes at a drag strip. MaxCool works by engaging the radiator fan, setting lower coolant target temperatures (72°C), activating the electronic thermostat, and setting water pumps to high cooling mode. Activated via the “LIVE” tab in the MHD app under “MHD+ Live Adjust,” MaxCool remains active until manually deactivated or the engine is shut off.
-
MHD Real-Time Tuning: Experience revolutionary real-time tuning for modern BMWs. This feature allows custom tuners to edit all major engine tables (including map switch and flex fuel slots) live, with the engine running. Real-time tuning of additional tables, including Advanced ReFlex PI control, is continuously being added.
