Pairs well with
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 steering wheel cruise button press and the Accelerator pedal allowing for insta-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 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)
- Transmission Torque Limiter disabled in software
