World’s First, Most Advanced, and Widely Adopted cloud-based flash tuning platform for the BMW F and G series vehicles!
Our latest development includes the addition of the bootmod3 CustomROM features that add advanced end user and tuning features such as:

• AntiLag – build boost while stationary or rolling by using the steering wheel cruise button press and the Accelerator pedal, allowing for instant-boost when roll racing or launching
• Map Switching – On-The-Fly using steering wheel cruise control buttons. Flash the vehicle once and have access to 4 switchable maps on the steering wheel, changing the calibration entirely from one map slot to the next.
• Flex Fuel Tuning – Tune for any Ethanol blend by having a Flex Fuel sensor report Ethanol % to the engine control unit (DME) and have it manage the tune from regular petrol (0% Ethanol) to 100%, without re-flashing
• New Map Editor – advanced tuning editor with close to 5000 tuning tables available
• Datalogging of over 80 advanced (RAM) channels and hundreds of others available at the highest throughput of any tool available on the market today
• Ethanol In-Dash Indicator – software changes applied to the DME to allow checking of your Ethanol content as reported by the Flex Fuel Sensor in the vehicle’s dash on the RPM gauge (e.g., 2000rpm = 20% ethanol, 5500rpm = 55% ethanol)
• The transmission Torque Limiter was disabled in the software

Cloud-based solution with a web-based interface for use on macOS, Windows, and mobile apps for iOS and Android. Developed and tested in-house from the ground up over the course of almost 2 years before its November 2016 debut with new features and updates being added regularly, it makes the bootmod3 platform a custom BMW factory DME tuning solution like no other on the market today.
Build the ultimate tune for your S58 powered vehicle and go from stock to full race calibration, and everywhere in between, with a map switch in the provided mobile app. bootmod3 calibrates the factory vehicle modules over the OBD port in just 3 minutes, switching among maps in seconds, in the convenience of your driveway or anywhere internet access is available.
