The same team who produced the Fuelpak FP3 that you know and love has done it again with the Fuelpak FP4! The Vance and Hines FuelPak FP4 is the most intuitive fuel management tool on the market, it allows you to change your motorcycle's tune, view live sensor data, and clear trouble codes right from your smartphone!
The FP4 is able to utilize data from your OEM engine management sensors to create a custom tune just for your bike using the AutoTune feature. For advanced users who want to get more hands on, the FP4 gives you complete access to critical ECU tables so you can see and adjust every aspect of your tune. The FP4 can make changes to your idle RPM, raise your rev limit, or adjust tables including VE, Target Air Fuel Ratio, and Spark Advance all from an app right on your phone.
Note: The FP4 is intended for Stage 1 applications, maps for Stage 2 and Stage 3 applications may not be available. Contact Vance and Hines for current map availability.
