Harleys are arguably the most customizable bikes out there and that is why so many people love them. Of course, engine and other performance mods are at the top of the list when it comes to making a bike your own. New pipes, high flow air filter and the list goes on. All of the good stuff to make that V-twin rumble to your liking. There’s just one problem. When you make those performance mods, especially on an EFI, you need to update your fuel mapping. If you don’t, the increased airflow will make your bike run lean.
In the past, you had to bring your bike into the shop and put on a Dyno with it hooked up to computers to get the right fuel mapping. This is not cheap and can be a pain for the average time strapped rider. Fortunately, fuel controllers like the Vance & Hines Fuelpak came along and allowed you to change the mapping yourself, but they still required a little bit of work and the adjustability still wasn’t the greatest. Now, Vance & Hines has released the Fuelpak FP3 and it is changing the game of fuel management.
So what makes the new FP3 so amazing? It’s a combination of a few things. First and foremost, with the FP3, you can now recalibrate your Harley’s engine parameters wirelessly through an app on your iPhone or Android smartphone. With one simple plug, the FP3 can be installed and connected to the new Harley HDLAN (CAN Bus) system and you are ready to start modifying.
Say you just installed some new pipes and air cleaner on your bike. To tune it with the FP3, all that you need to do is go onto the smartphone app with the Fuelpak plugged in. The app has an enormous list of fuel maps to choose from that comes straight from the Vance & Hines library. The mods that you make don’t even have to be from Vance & Hines. Their engineers do extensive testing with many of their competitors’ exhausts and other performance mods to ensure that you will have the right fuel map.
Still don’t like the results from the pre-canned maps? The Autotune feature allows you to tweak the mapping to get even more precise results. The FP3 communicates with all of the factory sensors on the bike to allow you to fine tune it. This is perfect for unique components or even to account for different grades of fuel.
Once you update the mapping on your bike, you’re going to be curious to see the effects. You will certainly feel the difference while you’re riding, but now you can see the actual data too. With the FP3 connected, you can see exactly what’s going on with the Live Sensor Data on your phone. The app will display your speed, RPM, cylinder head temperature, voltage, gear selection and other info that is vital to your bike. You can even read trouble codes that are brought up on your bike so you no longer have to bring it in to get hooked up.
The FP3 uses Flash Technology to make the changes. This means that once you flash the new mapping to the bike’s system, you can remove the Fuelpak and store it away. You won’t have access to the Live Sensor Data, but the mapping will remain updated.
As of now, the Fuelpak FP3 is only compatible with the late model Harleys that have the HDLAN or CAN Bus system. This includes Sportster, Dyna, Softail, Touring and Trike models with maps on the way for the 110ci CVO models. If you don’t have a bike with that system, you can always use the previous models of the Fuelpak to get amazing results. You can learn more about the Vance & Hines Fuelpak here.
