Wake up your touring bagger's throttle response and optimize your fuel delivery curves by plugging in the high-performance Vance & Hines Fuelpak FP4 Tuning Module (2014-2020 Harley Touring). Custom-engineered for full-size baggers, this compact, pocket-sized ECU flasher bypasses restrictive factory tuning software, allowing you to calibrate your engine maps directly from your smartphone for maximum roll-on acceleration and cooler engine operating temperatures.
Stock touring bikes are mapped from the factory to run aggressively lean, which generates intense engine bay heat and can cause frustrating deceleration popping or flat spots in your mid-range power band. Vance & Hines eliminates this sluggish throttle response by updating the FP4 platform with a lightning-fast internal microprocessor. Operating seamlessly through a secure Bluetooth connection, the FP4 links your iOS or Android smartphone to your bike's computer. It gives you instant access to a vast cloud database of dyno-tested maps built for specific exhaust and air filter setups, immediately enhancing your fuel trim cells to maximize low-end torque and horsepower output across the entire RPM range.
Active Auto-Tune & Live Cockpit Gauges:
Unlike basic piggyback tuner boxes that only distort sensor voltages, the FP4 completely overwrites your factory computer memory for smooth, reliable power. While you track down miles on the highway or blast through winding roads, the built-in Auto-Tune algorithm works continuously. It leverages your bike's original O2 sensors to log real-time data across varying altitudes and loads, molding a highly customized map tailored specifically to your exact riding style. The mobile app also doubles as a fully functional digital dashboard, projecting live sensor feeds including current gear positioning, exact cylinder head temperature, air-fuel ratios, and battery voltage levels in real time.
Mechanical Specifications & Interface Layout:
- Data Interface Pinout: Model-specific 6-pin diagnostic plug interface configuration.
- Wireless Connectivity Protocol: High-speed Bluetooth smart technology for rapid data flashing operations.
- Chassis Housing Build: Compact, heavy-duty molded polymer enclosure designed to tuck away cleanly under your side cover or seat.
- App Interface Compatibility: Free dedicated Vance & Hines FP4 mobile app interface (Supports iOS and Android).
- Status Indicators: Outfitted with bright external LED diagnostic lights to confirm power connectivity and active Bluetooth syncing instantly.
Guaranteed Vehicle Fitment Validation:
The Vance & Hines FP4 Tuning Module features a specialized data protocol layer engineered explicitly to match the electronics architecture of 2014, 2015, 2016, 2017, 2018, 2019, and 2020 Harley-Davidson Touring platforms. It provides an immediate plug-and-play electronics performance upgrade for the following lineups: Street Glide, Road Glide, Road King, Electra Glide, Ultra Classic, and corresponding Tri-Glide or CVO bagger configurations. Please Note: This tuner permanently binds its internal memory to your motorcycle's unique VIN code during the very first flash sequence and cannot be unlocked or transferred to any other vehicle later on.
Installation Tip: Electronics and powertrain safety is paramount. Always ensure your vehicle's battery is fully charged or connected to a reliable battery tender prior to executing a flash download. Interrupting power to the module or turning off the ignition switch during an active ECM flash sequence can corrupt the internal memory of your vehicle's computer.
