Bootmod3 - protuningfreaks

bootmod3 is a full custom tuning platform for the factory engine computer (DME) available for Windows, macOS and mobile apps for iOS and Android. Users can change their tunes through the OBD port in their own driveway using the web or mobile apps taking just seconds to do so.

Up until bootmod3 came into existence there were two popular ways of tuning the BMW F series, using a piggyback device to just add boost, and the other, by sending your ECU (DME) out for a one time flash to a tuner of your choice.
