fuelpak decel pop

Decel Pop

Decel pop reduces the amount of decel pop that riders experience. The feature increases the amount of fuel in the 0% TPS column of the Target AFR (Air Fuel Ratio) table. This in turn reduces the amount of “popping”.

fuelpak dtc reader

DTC Information

The FP3 can already read and clear trouble codes. Now it takes it one step further, giving you a specific description of that trouble code to better help diagnose the potential cause(s).

fuelpak fuel economy

Fuel Economy

Fuel economy will read the current fuel economy in real time. The Average Fuel Economy keeps track of fuel usage over time and calculates the overall fuel economy.

fuelpak horsepower

Power / Torque

Power and Torque allow the user to see the current power/torque output of the engine – these values are not as precise as a dyno session, but are pretty close and fun to view.

fuelpak camshaft

Camshaft Support

Fuelpak FP3 features camshafts for your specific application, whether you’re a Sportster, Twin Cam, or Milwaukee-8 owner. All customers have to do is select the desired camshaft and flash the change into the ECM.

How do I get the app?

Fuelpak FP3 is available in the App Store (iOS) or Google Play Store (Android)

What is the warranty on the Fuelpak FP3?

Vance & Hines offers an extensive one year warranty on the Fuelpak FP3.

How are your maps made?

All of our maps are made on a dyno and verified on the road with the engine/pipe combination listed. Every map goes through a full tuning process and is reviewed by calibration engineers.

How does the Fuelpak FP3 work? What is the process?

1. CONNECT Plug the Fuelpak FP3 into your bike.
2. TUNE Select the map for your setup.
3. RIDE Enjoy the improved performance and responsiveness of your motorcycle

I'm unable to flash a map using the FP3, what should I do?

First, verify that your FP3 app is up to date through either the Apple App Store or Google Play Store. Next, connect to your bike and FP3. Verify that the firmware is up to date by going to 'Customer Support' and pressing 'Check for Firmware Update'. Install firmware update if available. If still unable to flash, go to 'Customer Support', ‘Vance & Hines Support’, and press 'Upload ECU Content', then try flashing again. Contact Vance & Hines customer support if the issue persists.

How do I autotune?

To Autotune your map, you must first flash a base map onto the bike, the closest V&H map to your configuration would be ideal. Then, select Autotune from the main menu and select 'Quick Setup'. Next, choose the map slot you would like to base the Autotune off of. This will initialize the Autotune process by flashing the bike. Now, go out and ride. The more varied types of riding you can do (stop and go, steady state, uphill, downhill, low rpm, high rpm, low and high throttle ranges, etc.) the better. We recommend 3 sessions, each approx. 30-60 minutes in length. 'Apply' the data after the 1st and 2nd session, 'Finish' the Autotune after the 3rd session. During Autotune you may experience issues such as poor cold start, poor throttle response, and general ride quality issues. These will resolve once you 'Finish' Autotune and the map is re-optimized.

How do I edit my map for camshafts and engine modifications?

Before making additional changes for camshaft(s) and/or engine modifications, you must first flash a base map onto the bike. Then, go to 'View/Edit Maps' and select the map you want to edit. Under the 'Air and Fuel' section you will find 'Camshafts'. Under the 'General' section you will find other critical tables such as displacement, injector size, and rev limit. These tables can also be found in the ‘Map Optimization’ menu from the ‘Main Menu’.

Does the Fuelpak FP3 marry to the motorcycle's ECM?

Yes, once a Fuelpak FP3 has been used to flash a bike it is permanently married to that ECM. You can use the same Fuelpak FP3 on other bikes to read/clear trouble codes and view live sensor data, but will not be able to flash a different bike.

I'm getting a U0100 error code after flashing with the Fuelpak FP3, is this normal?

Yes, the U0100 trouble code is a historic trouble code that occurs when flashing the ECM. You may have one or several after flashing, which is completely normal and will not trigger a check engine light. You can periodically clear these codes out through the FP3 app if they occur.

Does the Fuelpak FP3 have to stay plugged into the motorcycle or can it be taken off?

The Fuelpak FP3 may be removed from the motorcycle once the map has been flashed to the ECM. For Live Sensor Data and Diagnostic Code reading, or any other map editing or viewing, the Fuelpak FP3 must be plugged in, and your smartphone connected by Bluetooth.
