Description
MG Flasher is a mobile tuning App designed for BMW/Supra vehicles equipped with B48, B58, S58, N63, S63, and N74 engines. Flashing is done by OBD using ENET Wi-Fi. Flashing time on ENET is only 15 - 20 seconds! Disclaimer: For off-road use only.
*Initial flash/ECU unlock with ENET Wifi will take approximately 4 - 6 minutes.
Flashing your BMW with MG Flasher unlocks many features:
• Custom Options - pick and choose performance mods, exhaust, cooling, torque options, as well as custom code options + more.
• Switchable Maps On-The-Fly - WORLD'S FIRST SOLUTION FOR BMW B58/B48 - through a simple combination of cruise control buttons you can quickly select between mapping, without the need to reflash the vehicle! Currently available for gen 1 and 2 B48,B58 and S58.
• Dynamic Exhaust Burble On-The-Fly - via a simple combination of cruise control buttons you can change the intensity of the burbles whenever you like! Currently available for gen 1 and 2 B48,B58 and S58.
• Flex Fuel - Automatically adjusts engine calibration to any ethanol blend, with smart blending logic for smooth power delivery and full integration with sensor or manual override control. Live ethanol display, cruise-control adjustability, and instant cluster feedback.
• Max Cooling On-The-Fly - With a simple cruise control button combination sequence, you can enable the option without reflashing the car! Currently available for gen 1 and 2 B48,B58 and S58.
• Torque Limit Adjustability - TCU 8HP Limiter Lifted for all platforms! 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.
• Speed Limit Removal, Startup Roar, Torque by Gear Limiter available on select software
