How to Program a Vance & Hines Fuelpak

The Vance and Hines Fuelpak system is designed specially for monitoring and managing the fuel-to-air ratio on Harley-Davidson motorcycles. It complements the electronic fuel control capabilities of the Harley-Davidson Delphi fuel-injection system and ensures that the fuel pump delivers exactly the right amount of fuel to the motor in all riding conditions. The Fuelpak is highly recommended for use with an after-market exhaust system. Once you install a Vance and Hines Fuelpak, you need to program it according to the recommended settings for your particular motorcycle model and its after-market accessories.

Instructions

    • 1

      Install and mount your particular model of Fuelpak according to the installation instructions. Fully secure all Fuelpak connectors to the factory power or electronic control unit connectors. Push down on the connectors and snap them into place if they are loose.

    • 2

      Unscrew each of the four mounting screws that are located in the recessed slots at the top and bottom of the clear Fuelpak cover screen. Lift off the cover screen and set it aside along with the screws. If your Fuelpak has a black cover and no screws, snap off the protective cover by lifting the tabs holding the cover onto the unit and sliding them over the unit.

    • 3

      Turn on the main power and handlebar switches on your motorcycle without starting the engine. Wait a few seconds for the Fuelpak digital display to light up. If it does not light up, turn the power off and check to ensure all Fuelpak connectors are properly connected. Securely connect any loose connectors as per Step 1.

      Connect to the Internet and launch the browser. Type in the address of the Fuelpak homepage. Click on the arrow after the words "Quick map lookup" at the far right of the options bar on the homepage and then click the type of motorcycle you have on the map lookup drop-down menu.

    • 5

      Click the photograph that corresponds to the appearance of your Fuelpak. Wait a second for the "Map lookup" screen to appear.

    • 6

      Use the corresponding drop-down menus to specify your bike manufacturer, bike year, bike model, exhaust manufacturer, exhaust model, baffle type, ECM calibration and engine type. Click the "Help" prompt next to the baffle type, ECM calibration and engine type menus if you do not understand the options.

    • 7

      Click "Other" in the appropriate drop-down menu if none of the options match your specifications. If a "Map request form" screen appears as soon as you select "Other" in any menu, fill out the form according to the instructions and then click the "Submit" button at the bottom of the form. Wait one business day for a technician to contact you before proceeding to step 10.

    • 8

      Click the green "Go" button as soon as it appears. If an additional drop-down menu appears, select the choices that pertain to your particular modified engine in the appropriate drop-down fields. Wait a moment for the "Fuelpak search results" page to appear on your screen. This is your engine map. If you see a "Map request form" instead of "Fuelpak search results," see Step 7 above.

    • 9

      Check the specifications above "Your Fuelpak values" to ensure they properly match those of your motorcycle. If there is a discrepancy, return to the homepage and repeat Steps 4 to 8. Print your engine map using the printer command of your browser if necessary and desired.

    • 10

      Press the mode selector button at the center of the three buttons of your black-cased Fuelpak or at the left of the first digit in the display of your clear-cased Fuelpak. Ensure the digit "1" shows in the left digital display.

    • 11

      Press the right plus (+) or left minus (-) button located below the display of your black-cased Fuelpak or the top plus (+) or bottom minus (-) button located to the right of the digital display on your clear-cased Fuelpak until the numbers in the right-hand digital display match the "Value" listed below "Mode 1" on your engine map page. For instance, if the number 10 is listed for Mode 1, press the (+) button until the right-hand display reads "10."

    • 12

      Press the mode button again and repeat Step 11 until you have completed entering values for all modes listed on your engine map. Skip to the next mode by pressing the mode selector button again if N/A is listed as the value for any mode on your engine map. When you get to mode 18, you may need to perform the process listed in Step 13 - consult your Fuelpak owner's manual to see if it is necessary for your model.

    • 13

      Press the mode selector to move to mode 19 after you have finished entering the values for the first 18 modes. Twist open your motorcycle throttle to full position and then return it to idle position. Press twice on the mode select button to advance to mode 21 and verify that it reads "0." Open the throttle approximately half-way and ensure the display reads "50." Open the throttle fully and ensure it reads "99."

    • 14

      Call the technical service number listed on the website and report your findings to a technician in the event any of the readings for any of the throttle positions are not correct. Follow any advice you receive before entering any remaining modes as per step 12.

    • 15

      Turn the power to your motorcycle off for a second and then turn it back on once you are finished inputting all values for each mode. Use the mode selector button to scroll through each mode and ensure the setting for it is correct according to your engine map.

    • 16

      Screw or snap the protective cover back on. Finish mounting your Fuelpak according to the directions for your model as necessary. You are now ready to use your Fuelpak-enhanced Harley-Davidson.
