the xied's were added by the indie that does my work. I had said that my bike gets hot and they installed them. I was concerned that they would create a conflict with the fuelpak, but instead they work wonderfully in tandem. Even vance and hines will tell you that the combo is excellent as one works open loop and the other closed. the xied's do not work well with the power commander, only the fuel pak.

I would agree with what others have said about the FuelPak. I have it on my '07 Fat Boy with V&H Big Shots Long pipes, stock engine and SE Stage 1 a/c. After I installed it, had it dynoed at the local dealer and the AFR is spot on. I'll be doing some engine/cam upgrades this winter and will need to ditch the FuelPak, but it has worked just fine with my current setup for the past 3 years.

I was under the assumption that V&H Works closely with Harley. I saw their stuff displayed on Harleys in the Harley booth of the NYC Bike Show this year. I have also heard they had something to do with some SE pipes.
(And yes, I know how the assume line goes! lol)

I had the V&H FuelPak on my 2010 Lo but I never had it dynoed. I was planning on putting it on my 2012 Lo when V&H came up with the new values on their website.

Could you educate me on these assumptions and give me some guidence on which type of fuel management to use on my new bike and why?

(By the way, I don't really care about it being a street legal fuel management system since my state decided last year to not require motorcycles to get a state inspection anymore. So I guess I would want the one with the best performance)

Thanks

The dyno guy assumes also.. if you do intake and exhaust, the stock ecm can not compensate and the bike runs lean.. there are way more advanced and expensive FMS out there. But the FP will allow for proper A/F adjustment. I never dyno'd my bike but it doesn't take a rocket scientist to know more air + more fuel = more power.. albeit maybe not much.. On a stock bike i wouldn't expect a FP to do anything except maybe be in the way... but i assume on that..

I was planning on putting on the 2012 Lo the Screaming Eagle Pro II slip ons and the K&N air filter and my FuelPak from my 2010 Lo.
What I'm trying to understand is: Does the FuelPak adjust the fuel mixture properly for this basic performance upgrade?
Why are they saying their dyno guy said the FuelPak is doing nothing for the motor?

just put these on my fat bob yesterday in combo with my fuel pak and noticed quite a difference in throttle roll all the way through the gears, used to feel that it would plane out towards the top of the gear on acceleration and than when i shift it would pull again. now it pulls all the way through the gear. if that makes sense. also noticed that the bike cools down much quicker when idling at a light. happy with the results so far.

anybody using this combo change any settings on there fuel pak after installing the xied's?

I have been looking at a FP as well and have looked at the Fuelpak settings online and underneath the guide it states this "Fuelpak maps are optimized to run on High-Flow air filters, but will also run on Stock models. NOTE: When using a Stock air filter, your bike may run slightly rich until you upgrade to a High-Flow air filter"

Not sure which type your running but this may help
