The Vance & Hines Fuelpak FP4 is a plug-in ECU tuner for the Harley-Davidson Pan America, 2021 onwards. It succeeds the widely used Fuelpak FP3 and puts tuning, live engine data and diagnostics in the Vance & Hines FP4 app on your phone, so you can flash a new calibration in the shed rather than booking dyno time.
It suits riders who have fitted a slip-on or full exhaust, an aftermarket air cleaner, or both, and want a calibration matched to that combination. You can pick a dyno-developed map from the Vance & Hines library for your specific parts, or use AutoTune to refine a map from your own riding, then flash the result back to the ECM.
Live sensor data and the ability to read and clear trouble codes also make it a useful everyday diagnostic tool, and Vance & Hines back the product with support from their own FP4 technicians.
