Reinvent your V-Twin’s performance footprint with the state-of-the-art Vance & Hines Fuelpak X (FPX) Tuning Module (Part #66055). Engineered explicitly for 2011–2020 Harley-Davidson Softail, 2014–2020 Touring, and 2014–2022 Sportster models utilizing a 6-pin data connection, the FPX represents a massive leap forward in aftermarket motorcycle electronics. More than a traditional fuel controller, this smartphone-driven flasher serves as an intelligent performance ecosystem that bridges raw engine power with active cloud convenience.
The Fuelpak X redefines ECM recalibration by combining Vance & Hines’ legendary, in-house library of dyno-tuned maps with smart mobile integration. By overlaying live engine sensor metrics with your phone’s GPS, the FPX lets you monitor operational vitals in real time while tracking custom data maps. Whether you are running slip-on mufflers, high-flow air intakes, or a full stage-one system, the FPX provides a smooth fuel profile, crisp throttle response, premium theft deterrents, and a highly responsive automated crash notification network.
ECU Management Disclaimer: Like prior Vance & Hines Fuelpak iterations, the FPX hardware permanently pairs and locks to your motorcycle's individual VIN during the very first calibration burn. The unit cannot be cleared or transferred to separate vehicles. Your original factory stock configuration map remains backed up in the cloud so you can flash the bike back to stock parameters at any point.
