MHD+ Features: Advanced Control and Customization at Your Fingertips

The MHD+ feature, unlocked within the Super License, takes customization and control to the next level. It unlocks special custom code that provides advanced functionalities for the discerning tuner.

MHD+ Feature Highlights:

1. On-the-Fly Map Switching: This groundbreaking feature allows you to switch between up to 4 different map slots in real-time, adapting to changing conditions or fuel quality without needing to re-flash. You can configure slots for different fuel octanes (pump gas and ethanol blends like E30) or even power levels. The power level slider lets you reduce power output from 100% down to 60% in 5% increments per map slot – ideal for creating a valet mode or a lower-power cruising map.

2. Antilag System: Experience rapid boost building with the integrated antilag system. By pressing and holding the cruise control RES button (or cruise control speed down on B58 GEN2) and applying heavy throttle, the system pre-spools the turbo, allowing for near-instantaneous boost when you release the button. Safeties are built-in for coolant temp, EGT, usage duration, and cooldown, and boost targets are adjustable for OTS maps.

3. Switchable Burble per Map Slot: Customize burble aggressiveness and duration independently for each map slot. Enjoy on-the-fly burble changes in conjunction with the MHD+ Map Switch feature.

4. On-The-Fly Exhaust Flap Control: Take manual control of your exhaust flap through the MHD+ Live Menu. Choose always open, always closed (opens at high load), or revert to OEM operation.

5. 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.

6. Full Motiv ReFlex Controller Integration: Seamless two-way CANBUS integration with the Motiv ReFlex controller unlocks advanced capabilities like DME limp mode for PI injector errors and DME control of external wastegates. B58 GEN2 even features MHD+ advanced ReFlex integration, enabling full control over supplemental port injection and auxiliary outputs directly within the DME for custom tunes.

7. Overrun Brap Noise: Emulate the distinctive “brap” noise of M-cars when releasing the throttle after acceleration, adding an extra layer of auditory excitement.

8. No Lift Shift (GEN2 Only): For 6MT (manual transmission) GEN2 cars, execute lightning-fast shifts without lifting off the throttle with No Lift Shift, optimizing acceleration.

9. Custom TCU Limiter Removal (GEN2 Only): Remove the TCU (Transmission Control Unit) limiter on GEN2 cars while retaining all safety features and OEM Launch Control for maximized acceleration.

10. KnockCEL: A valuable tool for custom tuners, KnockCEL allows the Check Engine Light (CEL) to blink when timing corrections reach a tuner-defined threshold, providing a visual warning of potential knock events.

11. MHD Real-Time Tuning (B58GEN2): For B58GEN2, experience the world’s first real-time, live tuning for modern BMWs. Custom tuners can edit major tables (including map switch and flex fuel slots) on-the-fly while the engine is running. Real-time tuning for additional tables, including Advanced ReFlex PI control, is continually being added.
