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
