Exhaust Burbles & Flaps On-The-Fly

On-The-Fly Instructions
Our unique function Dynamic Burble On-The-Fly is accessible through the Custom Code Menu via a simple combination of cruise control buttons. This feature allows you to change the intensity of the burbles ON THE FLY! There are 6 switchable levels available including Burble OFF in all modes.
Gen 1 and Gen 2 B48 and B58 BMWs supported

Through the Custom Code Menu, you can also open and close the Exhaust Flaps
on the fly with the cruise control rockers!

Antilag

Antilag (Rolling Launch) allows for building boost quicker to obtain a more powerful acceleration.

Youtube Video (Rolling Antilag Demo)
Antilag brings faster acceleration with the click of the cruise control button. Full in app adjustability in both Basic and Expert mode, allows for endless customization and fine tuning.

Antilag is accessible On-The-Fly through the Custom Code Menu. Disclaimer: For off-road/racing use only.

Max Cooling

On-The-Fly Instructions

There will now be two options available for cooling your engine: Regular Cooling and Max Cooling. Use “Regular Cooling” with regular driving, then switch to “Max Cooling” with a quick and easy cruise control button sequence in the Custom Code Menu. Max Cooling is achieved by lowering the target engine temperature and increasing the target intercooler coolant volume flow, targeting the temperature set in app while flashing.

Gen 1 and Gen 2 B48 and B58 BMWs supported!

TCU Torque Limiter & Remote Start

The TCU Torque limiter Bypass is available starting with Custom Code(CC) v0.5. This feature dynamically removes the torque limits set by the TCU when no intervention is required, and allows torque limitations when wheel slippage is detected (such as on a launch or gear change with a high power engine).

Additionally, starting with CC v0.5 Remote Start is also retained for cars that had the feature from factory.

Please see our Custom Code instructions for more information.

Flex Fuel Support

Flex Fuel is supported starting with Custom Code v7.2 (Coming Soon!).

With an Ethanol CAN Bus Sensor Installed, the ECU can read, log and display ethanol data while also using the data to automatically adjust the required parameters to the given ethanol level. Ethanol Content Display

If no Ethanol Content Sensor is installed, the user can specify ethanol content on the fly with cruise control rockers. This will also be used to automatically adjust the required parameters to the given ethanol level. Ethanol Content Override

Motiv ReFlex Support

MG Flasher will add the ability to log various parameters from the ReFlex module directly in the MG Flasher app with Custom Code (v7.2+ Coming Soon).

MG Flasher is able to log various parameters from the ReFlex module directly in the MG Flasher app, while also detecting errors from the ReFlex module and entering MG Flasher’s own Limp Mode.

Please see our instruction manual for up to date information on Motiv ReFlex Integration

Startup Roar & Cold Start

Users have the ability to disable the factory calibrated Cold Start. The Cold Start increases RPMs at idle when the engine is cold. Choosing this option lowers the RPMs which make for a quieter sound when starting a cold engine.

Alternatively, you can also enable the Startup Roar. This option enables a louder and more aggressive Startup Roar also known as “GTS Startup”. The roar duration and the aggression can be adjusted using the in app sliders. We recommend trying out various calibrations to decide which settings sound the best.
