Bootmod3 - ECU Performance Software (S58) - BMW G8X M2/M3/M4
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. 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 Map Switching 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. Its like getting 4 tunes for the price of one! 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
