MHD Super Licence for BMW S55 - Professionally Installed
Unlock the performance potential of your BMW S55-powered M vehicle with the MHD Super Licence, professionally supplied and configured by Gridline Custom Motorsports.
Developed specifically for BMW’s turbocharged M platforms, MHD provides comprehensive DME flash tuning with increased performance, enhanced throttle response, advanced monitoring and extensive calibration options while retaining the factory ECU’s underlying safety and protection strategies.
Unlike piggyback tuning systems, MHD recalibrates the factory DME directly, allowing the engine management system itself to control the requested performance changes.
Whether your S55 is completely stock, running common bolt-on modifications or has progressed to a more extensively modified setup, the MHD Super Licence provides the software platform required for OTS maps, custom tuning, monitoring, data logging and supported MHD+ features.
At Gridline Custom Motorsports, every MHD licence is professionally supplied and configured for your vehicle, ensuring the software and calibration are set up correctly for your BMW.

MHD+ Advanced Features
Supported S55 applications can take advantage of MHD+ functionality designed to provide greater control over the vehicle and calibration.
On-the-Fly Map Switching
Store multiple map configurations and switch between supported maps without having to perform a complete reflash each time.
This can be particularly useful for vehicles operating with different:
- Fuel grades
- Ethanol blends
- Power levels
- Daily-driving settings
- Track configurations
Adjustable Burble Settings
Configure exhaust overrun characteristics to suit the vehicle, exhaust system and selected calibration.
Live Exhaust Valve Control
Supported vehicles can provide control over exhaust-valve behaviour, allowing different configurations depending on the tune and vehicle.
Ethanol Content Monitoring
When combined with compatible ethanol-content hardware and an appropriate calibration, MHD can provide ethanol-content information for vehicles running ethanol-blended fuels.
Additional MHD+ Functionality
Depending on vehicle, software version and calibration, MHD+ can support additional performance and safety functionality for highly modified applications.
Specific functionality should be confirmed for your vehicle and intended setup before purchase.
MHD Monitor Licence
The MHD Monitor Licence turns your compatible mobile device into a powerful BMW diagnostic and data-logging tool.
Features Include
- Customisable live gauges
- Extensive live engine parameters
- High-speed data logging
- CSV log export for tuner analysis
- Built-in log viewing
- Diagnostic fault-code functionality
Monitor critical engine parameters such as:
- Boost pressure
- Boost target
- Lambda / AFR
- Intake-air temperature
- Ignition timing
- Coolant temperature
- Oil temperature
- Fuel pressure
- RPM
- Vehicle speed
- Wastegate duty cycle
- Additional supported DME parameters
Data logging is particularly important on modified S55 vehicles, allowing the calibration and engine operation to be evaluated under real-world load.
Included MHD OTS Performance Maps
The MHD Super Licence provides access to supported MHD Off-The-Shelf calibrations for the S55 platform.
Stage 1
Designed primarily for vehicles with stock or near-stock hardware.
Available calibrations vary depending on vehicle, fuel quality and software support.
Stage 1 provides increased boost, torque and power while retaining a setup suitable for vehicles that have not yet received the supporting hardware generally associated with Stage 2.
Stage 2
Designed for modified S55 vehicles with the appropriate supporting hardware.
Stage 2 calibrations provide increased performance for vehicles equipped with suitable airflow, exhaust and supporting modifications.
The correct calibration must always be selected according to the vehicle’s fuel, hardware and mechanical condition.
Supported BMW S55 Models
Compatible applications include:
- BMW F87 M2 Competition
- BMW F87 M2 CS
- BMW F80 M3
- BMW F82 M4
- BMW F83 M4 Convertible
Compatibility can vary according to production date, DME software and vehicle configuration.
