Our software is fully compatible with xHP transmission tuning
Designed for the drivers who want the most out of their stock component vehicle. This software is intended to safely maximize your vehicle’s potential performance. The power curve has been delicately engineered to eliminate any dips in the overall powerband as well as maximizing delivery of that power throughout the entire RPM range.

*Exhaust Burbles On-The-Fly (OTF) and all other OTF options are available for Gen 1 (CC v6.0+) and Gen 2 (CC v7.1+) B48/B58 BMWs. MINI, S58 and S63 support coming soon!
**Switchable Maps are currently available for Gen 1 & Gen 2 B48/B58 BMWs. Gen 1 OTS maps have map slots populated. Gen 2 OTS maps do not have switchable map slots populated. Gen 2 switchable map slots can be populated by custom tuners.
Software calibration without the need for any transmission tuning or skewing the torque/load calculation model maps. This allows for accurate calculations, smooth shifting and no software trickery. The factory torque limiter is set to 760 Nm (560 lb-ft) at the crank. We are the first to offer a solution to lift this limit up to 1000 Nm by using our custom code! The limit is adjustable in app.

Switchable Maps On-The-Fly
WORLD'S FIRST CRUISE CONTROL SOLUTION FOR BMW GEN 1 AND GEN 2 B58/B48
Through the control buttons you can quickly select between various maps without the need for a reflash!
*Gen 2 cars support switchable maps functionality, but map slots in MG Flasher OTS maps are currently empty. Please see our instructions below for details.
*MINIs, S58 and S63 switchable maps, including all ethanol maps, are under development.
For full updated instructions, please see the
User Manual
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 (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.
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!
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 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
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
Users have the ability to adjust the factory-calibrated Cold Start feature. Cold Start increases RPMs at idle when the engine is cold. Adjusting this setting allows for a quieter startup.
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.
For a full, detailed list of options offered by MG Flasher, please see our Custom Options page, as well as our Custom Code page.
Please refer to our User Manual for up to date information, and stay tuned for announcements regarding updates with new features on our social media pages!
