*The reprogramming function is blocked and incompatible with "Gen 2" Touring models (VVT / Center-Cooled 23-25 engines), as well as all models from 2025 onwards.
More than just a mapping tool, the Vance & Hines Fuelpak FPX embodies the future of connected motorcycles. Designed for the latest generation of Milwaukee-Eight and Revolution Max engines, it combines high-precision injection reprogramming with an intelligent ecosystem embedded in your smartphone (iOS / Android), radically transforming your riding experience.
Flash Reprogramming: Dyno expertise in your pocket
Powered by a new-generation high-speed processor, the FPX communicates via Bluetooth with your smartphone and gives you access to the massive Vance & Hines map library, developed on a dynamometer:
-
Instant Calibration: Adjust the air-fuel ratio (AFR), throttle response, and idle speed in minutes according to your setup (Stage 1, high-performance filter, full exhaust system).
-
Live Data: View engine speed (RPM), engine temperature, voltage, or air/fuel ratio in real-time directly on your screen.
Active Security: Electronic Anti-theft & Fall Detection
-
Anti-theft Technology: With a simple click from the app, remotely lock your bike's ECM. It becomes strictly impossible to start the engine, offering absolute protection against theft.
-
Crash Detection: In case of an impact or a heavy fall, the unit detects the shock and can automatically send a geo-localized alert SMS to your emergency contacts.
GPS Navigation & In-Ride Gamification
-
Integrated Turn-by-Turn GPS: The app guides you visually turn-by-turn, with the option to overlay your engine data gauges on the map.
-
Badges & Achievements: Track your GPS statistics, accumulate miles, unlock riding achievements, and challenge your friends or riders from around the world.
-
Digital Service Log: Set up your personalized maintenance reminders directly on your phone.
