Vance & Hines 14-20 Harley Davidson Touring Fuelpak X - 66055

The Vance & Hines 14-20 Harley-Davidson Touring Fuelpak X (Part #66055) is a next-generation flash tuner and connected-ride device built specifically for 2014-2020 Harley-Davidson Touring models equipped with CAN BUS wiring. Unlike a traditional tuner, the Fuelpak X (FPX) pairs Vance & Hines' in-house dyno-tuned fuel maps with live GPS and sensor data, turning your handlebar-mounted phone into a real-time performance and safety dashboard. Whether you're chasing more usable power from a new exhaust or want smarter theft protection and crash alerts on long rides, the FPX 66055 is designed to do more than just tune your bike.

Key Features & Benefits

• Extensive library of dyno-tuned maps — Vance & Hines builds and tests fuel maps in-house so your Touring model gets a tune matched to its setup, not a generic file.
• Live data overlay with GPS integration — track real-time engine and sensor data alongside your location for a clearer picture of how your bike is running on the road.
• Turn-by-turn navigation — built-in smart navigation keeps route info on the same device you're already using for tuning and diagnostics.
• Anti-theft technology — the FPX can remotely prevent the motorcycle from starting without reflashing the ECM, adding a layer of security beyond a standard alarm.
• Automatic crash detection — the system can detect a crash and notify your designated emergency contact.
• Customizable service tracker — keep maintenance intervals logged and organized directly through the FPX ecosystem.
• GPS-based achievements and rewards — riders can unlock bragging-rights milestones and perks the more they ride.
• Live customer service support — Vance & Hines offers live agents specifically for FPX tuning and setup questions.

Fitment

The 66055 Fuelpak X is designed for 2014-2020 Harley-Davidson Touring models using CAN BUS electronics. It is not the correct part number for earlier or later platforms — Vance & Hines uses separate Fuelpak X SKUs for other wiring generations, including the 66057 for 2007-2013 J1850-equipped bikes and the 66053 for 2021-and-newer CAN BUS models. If you're unsure which connector type your bike uses, our team can help confirm the correct FPX unit before you order.
