Features available only through M Engineering and our dealers.
Live Map Switching - This feature allows multiple calibrations to be stored on the ECU at one time. Many of you are already familiar with this feature. Utilizing the cruise control stalk, you can quickly and easily switch between maps while the car is running. This is often utilized when changing octane but can be designed for various other situations such as pops and bangs, valet mode, running alternative fuels such as ethanol, etc... We have a wide range of control over map slots so if you have an idea for a feature you would like to let us know! More Info on how Live Map Switching works and directions you can visit here
Rolling Anti-Lag - Roll Racing at the track has gained popularity over the years and this feature comes highly requested. Rolling Anti-Lag works by inhibiting acceleration while simultaneously building boost. This is all done via the cruise control stalk and accelerator pedal. Simply get to the roll speed you wish to accelerate from, engage the cruise control stalk, press the accelerator, let boost build for 1-2 seconds, release the cruise control, and HANG ON! You will now accelerate with full boost. Rolling boost is a psi-based target system and boost during Rolling Anti-Lag can be calibrated independently of target boost.
Custom PSI-Based Boost Control – This allows for complete control of the boost control system while also retaining torque control safety systems. The boost control system will precisely control torque and allow these high revving engines to make peak power without increasing cylinder pressures and torque to dangerous, rod bending, levels. Particularly beneficial with aftermarket turbos.
M-Logger - A feature in the M Tuner Suite that allows end users to data log up to 75 parameters at speeds of up to 120Hz. The parameters logged are vital to proper engine health and function. Different parameters can be logged depending on situations based on logging profiles. This is particularly useful when diagnosing a mechanical issue with the car or revising a calibration to optimize it for your parts configuration if it lies outside of our standard off the shelf type recommendations.
Clear Faults - A feature in the M Tuner Suite that allows end users to clear faults in many of the most fault prone modules such as the ECU, PCCU, ESC, SRS.
Dyno Mode Enable/Disable - A feature in the M Tuner that allows the end user to put their McLaren in dyno mode for independent power verification or custom dyno tuning. All McLaren models require dyno mode to operate properly on a roller chassis dyno.
Auto Start/Stop Disable - This feature disables the engine from turning off when coming to a stop in normal mode. The engine shutting off in a high-performance car is usually more startling than it is helpful and was also a highly requested feature in the cars that support auto start/stop.
Left Foot Braking - This is a nice feature to have for track enthusiasts who like to use both feet while racing. This extends the time you can press the brake pedal before all throttle input is cut off allowing racers to exit corners with more aggression. This does not disable the OEM safety control and will still perform as desired in an emergency situation.
Kickdown Disable - The kickdown allows for the transmission to automatically downshift if it deems it is necessary in manual mode. Many folks who track their car have their shift points well planned out in advance for every corner and unpredictable shifting can be unsettling. This feature disables the kickdown, however special car needs to be taken not to lug the car in manual modes.
Loud Start* - This is not a M Engineering exclusive feature, but one designed by McLaren but disabled in code. We simply enable it in code. When enabled, and the vehicle is up to operating temperature, the user can start the car with a much more aggressive rev. Simply turn on the active panel and set both modes to track before starting the car.
