• A stable internet connection for downloading the app and maps.

2.3. Reverting to the Factory Settings

You can revert your vehicle to the factory OEM flash at any point using the MHD Flasher app. No initial backup is necessary, making it easy to switch back whenever needed.

3. Exploring the Flasher License Features

The Flasher License is the base of the MHD Super License, unlocking essential tuning capabilities. It enables you to flash your DME with various maps, read and delete engine codes, and reset adaptations.

3.1. Stage 0 Stock Power

The Stage 0 option allows you to flash your DME while maintaining stock power levels. This is ideal for users who want to take advantage of other flash options without increasing engine output. This allows you to customize parameters without altering the base performance.

3.2. Reading and Deleting Engine Codes

The Flasher License allows you to read and delete engine codes, helping you diagnose and resolve issues quickly. This feature is invaluable for maintaining your vehicle’s health and performance. Regularly checking and clearing codes can prevent minor problems from becoming major repairs, saving time and money.

3.3. Available Flash Options

The Flasher License unlocks several customizable flash options:

• Exhaust Burble: Adjust duration, aggressiveness, minimum RPM, and minimum speed for exhaust burbles.
• Kick-Down Deactivation: Disable the kick-down feature for more control over gear shifts.
• Cold Start Noise Reduction: Reduce noise during cold starts.
• Variable Coolant Targets: Adjust coolant temperature targets for optimal engine performance.
• Top Speed Limiter (Vmax) Removal: Remove the top speed limiter for unrestricted performance.
• Linear Throttle Mapping: Change throttle response for a more linear feel.
• Individual Minimum Idle RPM: Set a custom minimum idle RPM.
• Support for Aftermarket Parts: Optimize your tune for various aftermarket parts.

4. Unlocking the Power of MHD+

MHD+ unlocks special custom code features that enhance your tuning experience. This includes on-the-fly map switching, antilag, switchable burble settings, and more.

4.1. On the Fly Map Switching

This feature allows you to select four different map slots to adjust for fuel quality or power levels on the go. This is particularly useful for adapting to different fuel grades (like pump gas or E30) or reducing power for valet mode or cruising. It adds a layer of versatility that adapts to your immediate driving needs.

4.1.1. How to Use On the Fly Map Switching

1. Assign maps to slots: Use the MHD app to assign different maps to the four available slots.
2. Adjust fuel quality: Configure slots for different fuel qualities (e.g., 91 octane, 93 octane, E30).
3. Reduce power: Use the slider to reduce power output in each map slot, adjustable from 100% to 50% in 5% increments.

4.2. Antilag System

The antilag feature allows you to build boost while limiting acceleration, providing a quick takeoff once released. This is ideal for drag racing or spirited driving where immediate power is needed. It ensures that the turbocharger is spooled and ready to deliver maximum thrust when you need it.

4.2.1. Activating Antilag

1. Press and hold: Press and hold the volume down button on your steering wheel or cruise control stalk.
2. Apply heavy throttle: Simultaneously apply heavy throttle to engage the antilag system.
3. Release: Once boost is built, release the button/stalk and accelerate.

4.2.2. Safety Features

MHD’s antilag system includes several safety features:

• Coolant temp monitoring: Prevents activation if coolant temperature is too high.
• EGT temp monitoring: Monitors exhaust gas temperature to prevent overheating.
• Max duration limit: Limits the duration of antilag use to prevent damage.
• Cooldown time: Requires a cooldown period between uses.

4.3. Switchable Burble per Map Slot

Customize exhaust burbles for each map slot with this feature. Set up your main map (Map 1) with specific burble settings and adjust aggressiveness and duration for all other slots. This allows for on-the-fly burble changes using the MHD+ Map Switch feature.

4.4. On The Fly Exhaust Flap Control

Control your exhaust flap via the MHD+ Live Menu. Choose from always open, always closed (opens at high load), or OEM operation. This gives you control over exhaust sound and performance.

4.5. Ethanol Content Quick View

If you have a compatible Ethanol Content Analyzer installed, you can view the ethanol content via the MHD+ Live Menu. This helps you monitor and adjust your tune for optimal performance with ethanol blends.

4.6. Full Integration with Motiv ReFlex Controller

The MHD Super License offers full and native integration with the Motiv ReFlex controller. This 2-way CANBUS integration enables advanced capabilities, such as DME limp mode when there is a PI injector error and DME control of external wastegates.

4.7. Overrun Brap Noise

Enjoy the special “brap” noise M-cars make when letting off the throttle after accelerating. This feature adds an aggressive sound to your driving experience.

4.8. No Lift Shift for Manual Cars

Manual transmission vehicles can experience WOT shifts without lifting their foot off the accelerator pedal. This allows for quicker shifts and more boost in the next gear, eliminating the “shift bog” some experience with traditional WOT shifting.

4.9. PI Safety (coil cut)

This unique feature prevents lean cylinder issues when the DME cuts injection to individual cylinders. It prevents the cylinder’s coil from firing, preventing an extremely lean mixture of only the PI share of fuel being ignited. This makes MHD a safe platform for running supplemental port injection.

5. Utilizing the Monitor License for Engine Health

The Monitor License allows you to monitor your engine’s behavior with a configurable gauge layout. You can display up to 8 fully adjustable gauges and log over 50 engine parameters in the background.

5.1. Key Parameters to Monitor

Some of the available monitors include:

• Boost
• Boost Target
• Lambda (AFR)
• Intake Air Temp (IAT)
• Ignition Timing per Cylinder
• Coolant Temperature
• Oil Temperature
• Oil Pressure
• Transmission Temperature
• High Pressure Fuel Pump (HPFP)
• Throttle Position
• Wastegate Duty-Cycle (WGDC)
• RPM
• Speed
• EGT

5.2. Advanced Monitoring

Advanced parameters not exposed by BMW are available for fine monitoring and tuning, such as timing corrections per cylinder, boost setpoint, and active torque limiter.

5.3. Logging and Analysis

Activate the logging mode to save data to a standard CSV file for later analysis using the built-in log viewer. CARDIAGTECH.NET also provides free log analysis to help you optimize your tune.
