S55 Tune

The bootmod3 S55 Tune represents the world's first, most advanced, and widely adopted cloud-based flash tuning platform designed specifically for BMW F and G series vehicles with S55 engines. This powerful system allows you to transform your stock vehicle into a full-race calibration or anything in between, with the convenience of map switching directly from your mobile app. The bootmod3 platform calibrates your vehicle's factory modules through the OBD port in a matter of minutes, right from your driveway, provided you have internet access. Key CustomROM features include on-the-fly map switching using steering wheel cruise control buttons, enabling access to four distinct calibrations without re-flashing. It also supports Flex Fuel Tuning, allowing seamless adjustments for any ethanol blend from 0% to 100% by integrating a Flex Fuel sensor. Additionally, the platform offers an AntiLag feature for building boost while stationary or rolling, a new Map Editor with nearly 5000 tuning tables, and advanced datalogging capabilities for over 80 RAM channels. Further enhancing the user experience, bootmod3 includes features like an Ethanol In-Dash Indicator, a mobile app (iOS and Android) and web interface, one included OTS map with additional free maps, and cloud-based storage for map data and datalogs. It also provides a GTS/CS Transmission Flash for DCT-equipped vehicles and the ability to revert to stock performance maps. Diagnostics are streamlined, allowing you to read and clear trouble codes, reset learned adaptations, and perform ECU power resets. The S55 Tune is compatible with the following BMW S55 engine vehicles: 2014-2020 F80 M3, 2014-2020 F82/F83 M4, and 2018-present F87 M2 Competition. Please note that a bootmod3 Wireless OBD WiFi Flash Adapter or OBD ENET cable is required and sold separately. Additionally, 2019+ S55 models with March 2019 software may require a bench unlock; contact support for details. It is important to be aware that using performance tuning parts may void your vehicle's factory warranty and some modifications may not be legal for on-highway use.
