World's First, Most Advanced and Widely Adopted cloud-based flash tuning platform for the BMW F and G series vehicles!

Build the ultimate tune for your S55 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 a matter of minutes in the convenience of your driveway or anywhere internet access is available.

Our latest development includes the addition of the bootmod3 CustomROM features that add advanced end user and tuning features such as:

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

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

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)
