We all love that sweet rumble of a Harley exhaust. That’s why so many of us riders choose to customize our bikes by putting on a performance aftermarket exhaust, like a system from the lineup of Vance and Hines. When you add performance exhaust, you will undoubtedly get more throttle response and overall power from your motorcycle. The one thing that many riders forget about, though, is that adding performance parts will require you to re-tune your bike. Fuel injected Harleys do have an ECU (electronic control unit) that is programmed to deliver the correct air/fuel mixture for the stock bike, but it cannot compensate for aftermarket performance exhaust and air filter. When a performance exhaust system is added, your motorcycle will run much leaner than it normally would with stock exhaust. Since you now must re-tune your Harley, you have a few options. You can have your bike tuned on a Dyno with computers, or you can go the easy route of adding a Vance and Hines Fuelpak.
So what exactly is the Fuelpak? The Vance and Hines team has created the easiest way to tune your Harley Davidson® by creating the Fuelpak. After being programmed, the Fuelpak is able to not only add fuel when needed, but unlike some other tuners, it is able to take away fuel from the air/fuel ratio. This will give your bike the most refined fuel system for ultimate performance and throttle response.
Don’t worry if you’re not a Harley mechanic. The tuner was created to be installed and used by riders of all mechanical skill levels. The only tools needed to install the Fuelpak are a #1 and #2 Phillip’s screwdriver, a T-40 Torx socket and a 3/16 Allen wrench. The installation only takes four steps. First you need to remove the side cover and the seat. Next, you will need to detach the electrical box and unplug your Harley’s ECU. When that is complete you will have to route the harness through the frame and finally install the Fuelpak by simply plugging it into the ECU and stock wiring harness using a t-tap and OEM style connectors. The Fuelpak is visually unnoticeable on your bike after it has been fully installed. Where you will notice it, is when you twist the throttle on your Harley and feel the improved response.
Programming the tuner to work for your bike and new exhaust system is just as easy as it is to install. With the ignition turned on use the provided setting chart to calibrate your throttle positioning sensor by entering your specific map into the Fuelpak. After the correct values are entered, turn off the ignition and put your side cover and seat back on and you are ready to ride with improved performance. The Fuelpak can even be used with other performance exhaust systems. To get the map, contact Vance and Hines and they will be able to give you the right values. If you want to get your bike back to stock settings, all you have to do is simply uninstall the Fuelpak.
Harleys are meant to perform at the highest of levels. With a Vance and Hines exhaust system and Fuelpak installed on your bike, you will be able to get the most out of your bike.
