With Harley Mastertune, you can control your bike's air/fuel mixture and timing to get the best performance possible. Mastertune is a Windows-based program that allows you to tune your bike without having to add on a separate unit. With over 20 different tables and parameters to follow on the program, you will be able to tune your bike to perform exactly how you want. The tables are presented in 2D and 3D graphing to help you visualize the mapping. The program will also save and restore the stock programming if you ever need to go back to it. With the Harley TTS Mastertune program, you will also be able to change the RPM limit and speedometer settings of your motorcycle.
