bootmod3 is the first and most widely adopted flash tuning platform for BMW F and G series vehicles, as well as the new A90/A91 Toyota Supra. This free software allows BMW owners to program their factory engine control unit (ECU/DME) and transmission (TCU) over the OBD diagnostic port, unlocking the full performance potential of their vehicles.

One of the standout features of bootmod3 is the ability to switch between different maps using the steering wheel controls. This allows users to easily switch between pump gas and race gas maps, giving them the flexibility to optimize their vehicle's performance for different driving conditions. Additionally, bootmod3 offers flex fuel tuning, anti-lag functionality, and the ability to check ethanol content on the RPM gauge in the dashboard.

With the all-new map editor, users can customize their performance tuning to their specific needs. Whether they want to enhance performance, sound, or fuel economy, bootmod3 provides a user-friendly interface for tailoring the tuning to their preferences. The software also offers live monitoring of engine behavior, allowing users to keep an eye on various engine parameters such as torque limits, boost, ignition timing, and fuel targets.

bootmod3 supports a wide range of BMW vehicles, including the F8x M3 and M4, F2x F3x 135i, 235i, 335i, and 435i, F1x 535i, 640i, M5, M6, 550i, 650i, X5, and X6, and the F87 M2 and M2 Competition, among others. It also supports certain Toyota Supra models.

Please note that bootmod3 is intended for off-road and competition use only, and the use of this software may void portions of the vehicle's factory warranty. Additionally, some features may not be legal for on-highway use. It is important for users to be aware of their local regulations and to understand the potential impact on their vehicle's warranty before using bootmod3.
