The Fuelpak FP3 for Harley-Davidson models connects wirelessly by Bluetooth to iPhone or Android Smartphones, apps available with app store or playstore. It plugs into the OBD receptacle and uses Flash technology to recalibrate engine parameters and mapping for exhaust systems and other performance upgrades downloaded from the expansive library of calibrations developed by Vance & Hines. To flash your blackbox memory you need an active internet connection, the maps are directly transmitted from a Vance & Hines server to the blackbox of your Harley.

Also standard for the Fuelpak FP3 is an Autotune feature, making use of all factory sensors to add another layer of precision tuning for specific requirements, whether tuning for unique components or different grades of fuel. And with the Fuelpak FP3 module plugged-in, Live Sensor Data can be viewed through the smartphone to display speed, RPM, cylinder head temperature, voltage, gear selection and other vital information.
