Vance and Hines Fuelpak 3



Installing a performance exhaust system is only your first step. Now, you need fuel management. You need Fuelpak.

Your fuel injected Harley Davidson is equipped with an ECU (electronic control unit) that’s programmed to deliver fuel to the motor based on an air/fuel ratio for a stock air filter and stock exhaust system. While the ECU can self-adjust for environmental factors such as temperature and altitude, it can’t adjust for mechanical changes like adding performance parts. When you install a performance exhaust system, your airflow changes, so you need a fuel management system that adjusts your air/fuel ratio to match the changes. That fuel management system is Fuelpak. The perfect combination with your performance exhaust system.

Fuelpak FP3

The Fuelpak FP3 is the best-selling ECU tuner in the world for Harley-Davidson motorcycles because it is the most intuitive tool on the market, giving you the power to control every aspect of your motorcycle’s tune, view live sensor data, calibrate your speedometer, read and clear trouble codes, utilize a live sensor data display, and offers best in industry support from our FP3 technicians, all from your smartphone. The Fuelpak FP3 also backs up your OEM calibration and gives you access to Vance & Hines’ library of thousands of dyno-tuned maps, made by our trained dyno technicians and designed for any combination of performance exhausts and air cleaner components.

Ahead of the competition, Fuelpak is the most advanced system of it’s type. Nothing will compare.

As shown in the illustration, your stock air/fuel ratio runs just slightly lean, however, when you install an aftermarket exhaust, that ratio changes, becoming even leaner. The white dashed line reflects the baseline air/fuel ratio and where you want to be for optimum throttle response. Unlike other fuel management systems that can only add fuel, Fuelpak adds and takes away fuel, allowing for a more precise range of refinement in your air/fuel ratio. Designed and manufactured entirely in-house, our technical staff is constantly at work developing custom fuel maps for popular brands.

Don’t settle for a system that is difficult to install. Afterall, you want to focus on what you enjoy most. Riding.

When our engineering staff designed Fuelpak, the focus was on making installation and use as simple as possible. Fuelpak plugs directly into the factory wiring harness and ECU using a t-tap and OEM style connectors to stay fastened securely to your bike. Fuelpak fits so discreetly that, with the exception of the improved throttle response and rideability, you won’t even know it’s there. And should you ever remove Fuelpak, your motorcycle will return to operating at it’s original factory settings.

No computers needed, no need to tune on a dyno. We did all the hard work for you.

Once the Fuelpak is installed, locate your fuel map from the setting chart provided or look it up here. Next, wth the ignition turned on, enter the values for your specific map directly into Fuelpak and calibrate your TPS (throttle position sensor). Finally, shut off the ignition, put the cover back on and you’re ready to ride. That’s the beauty of Fuelpak, you don’t need to use a computer or tune on a dyno because the settings you enter are the result of our extensive dyno and road testing to find the ideal fuel map for your Harley.

Customer questions & answers

Can this tune my bike which has a custom pipes on it ? ( no baffles)

Yes, absolutely.. as long as your bike is a 2014-2015.

Can this tune the bike for an intake modification only?
Yes it can. When you go through the setup process when it asks about what type of exhaust you will just put “stock”. When it asks for Intake/breather you will enter the type of intake you have.

PS…if you can’t find your tune…you can call V&H and they will either send you a custom tune for your bike or they will recommend one in the tuner thats correct for your mods.
Hope that helps!

Why is there no model number on this item?. What is the model number?

V&H part number is 66003 is a Vance and Hines FP3
Is this the latest fuelpak fp3? because v & h says it works for 2015 fxdl but this page does not.

Yes this is the latest fuelpak Fp3 and it does work with the 2015 lowrider.

i purchased this particular model for my 2015 Streetglide FLHX. It should work for yours also. One thing to note. If using the auto tune feature be sure to follow the suggestions of riding through one full tank and then activate the map. during the one full tank on start up your bike will run rough.

Why does amazon say this won’t fit a 2014 flhx?
