The key function of the Tuning Dongle is to save the original EFI calibration. With this function the original calibration can be restored at any time, the tuning dongle also incorporates the tuning licence exclusively for one motorcycle and must be purchased for tuning of each individual motorcycle and will be mated to the ECM of that motorcycle. It enables ADVANCED MODE in the tuning software. Custom fuel maps and timing tables can be created as desired with the help of the AFR tuning monitor or downloaded from a database of preset maps.
