Installing USB Drivers
NOTE: The first time the VFI module is connected to a PC, the USB drivers will need to be installed for ProTune II to communicate with the VFI module. If
drivers have already been installed, you may skip this section.
1- Close all window applications including ProTune II.
2- Using a standard USB A to 5-pin Mini b cable, connect the mini-USB port on the case of the VFI module to an available USB port on the PC.
3- Turn on the ignition switch of the motorcycle and set the run/stop switch to “run”. Do not start the motorcycle at this time.
4- The PC will now recognize it has been connected to a VFI module and will start the process for installing the USB drivers. To complete the
process follow the steps below for the operating system used on your PC.
USB Driver Installation - Windows® XP
a- After a few moments the Found New Hardware Wizard will appear and ask if Windows can connect to the internet to search for driver.
Select No, not this time and click Next.
b- Select Install the software automatically (Recommended) from the list of options and click Next.
