Hello guys. Does anyone have any idea what the modes and values on a Vance and Hines fuelpak represent or ow to fine tune them? I have an 06 Bob with V&H sideshot pipes on a stock set-up, and using their Fuelpak map, I still get some back-firing now and then. I'd like to make the map richer, but I don't know how to adjust it.

Anyone have a clue?

Thanks,

Matt

 

It seems nobody knows what those numbers do and when and V&H aren't saying. Call them they will help you.

 

I read somewhere that Vance and Hines is actually working on releasing a manual telling what the modes actually are. They wanted to wait and see how well the fuel pack was going to sell before they released the info. Not real sure how accurate that is, but may be if you called them they'd be able to help you out.

Had the same problem with my 06 dyna and slipons. Called V/H and the gave me a new set of mapping values. Cut down on the back-firing. Still have a little popping at low speed but that is basicly how the fuelpak works.

MODE Value
1 5
2 5
3 6
4 4
5 5
6 14
7 12
8 16

10 8
11 2

looks like a throttle position breakdown in 5% increments and adding/removing fuel by percentage.

Those numbers aren't too different from what my PCIII map looks like, just without the engine RPM's.
