Had a baseline run today. The AFR was pretty lean, have an email to V and H to see if they can reccomend how I can add more fuel. Needs it in the cruise range, don't have the printout of the cruise, but it was a constant 15:1 . JeffyTune, any suggestions. Thanks.

I had mine on the dyno Saturday . And they said I was still lean at idle and cruise . But it is running much cooler ! So I sent an email to Vance & Hines . They said it was normal to show lean at idle . He didnt make any recomendations for cruise ?
But did suggest that I change mode 23 to 15 for
decell backfire !

So do I go Power commander or Fuelpak? Will either give me a bit more oohmpf?

06 Heritage, with SE Pro II slip-ons, SE air filter did the upgraded ECM via dealer basic Stage I.

So looking for opinions.

thanks

Hi.

On a 2006, and i will assume no O2 sensors, the Power commander will let you change the timing as well as fuel delivery.
But you should do this on a dyno to get it set right, the fuelpak is far more user friendly. letting you do it your self at home.

I like the fuelpak for stock stage one bikes, if you plan to do cams and head work in the future, the PC would do you better in the long run.

But If you are going that route, I would go with the SE Race tuner.

I agree it is far too lean. I would start by double checking to make sure you have the right fuel program, and the latest version, you can do that by logging onto Vance and Hines sight and going to the fuelpak page and loading in your spects and look to see what program comes up.
usually there programs are a bit on the rich side.

Iif the program is right, i would then go through the cells to make sure there all correct, and redo the cell 19 throttle calibration, it is very important it be spot on.
I use the two second method, one-one thousand close throttle to full open, and One- one thousand open to closed.

Got an email back from Adam at V and h. They increased the numbers in 4 cells. I'll try it this weekend.

Good to hear, please report back, and do share how much they suggested.

Peg_legs · 09-21-2007, 04:54 PM

Thanks Jeffytune for the link and suggestion.

I installed the Fatcat, big sucker and Fuel pak 2 nights ago and had allot of decel popping. Last night I switched 23 from 16 to 50 like I have read here and other forums, and now get a single backfire or something that sounds similar. Should I try 35? I also noticed some surging at low rpm's and am getting some blueing of the pipes. It is definitely faster and louder. I hope to get this all sorted out before a trip down to Panama City FL next weekend for the thunder on the Beach rally.

50 you say?
Wow usually they suggest going to 15 from 16, is it possible you miss heard there suggestion?
I would suggest you try the 15 in cell 23 and recalibrate cell 19 (throttle calibrate) and see if that helps, if it makes it worse, go back to the 50.

That is the cool thing about these fuelpaks, you can play with it a bit and go back all you want.

A single pop on a shift is usually you not shutting the throttle closed on shifting.

Peg_legs · 09-24-2007, 05:17 AM

just a follow up. My problem went away after reinstalling the pipes. An exhaust leak was the cause. Runs real smooth now. I have 16 in the 23 slot.

Good to hear.

I have a question about the install on the fuelpak. The instructions say to make sure all switches are off then unplug everything, then pull the battery then do what ever(I dont have the instructions infront of me)and then install the battery and then plug everything back in. My question is shouldnt you pull the battery and leave it out untill all the plugging & unplugging of the electric lines are finished. And what is the stage 1 kit on the ECU? I thought the stage 1 kit is the screaming eagle carb kit. I'm a fuel inj. virgin.
I was going to go with the cobra kit but didnt want to mess with alot of lines. Changing the exhaust & aircleaner is enough for me. If I wanted a fast bike I wouldnt have bought a Harley.

Hi.

I think on your night train, the battery removal maybe needed for access to where the unit mounts or where the ECU is mounted. I am not real sure where the ECU on a softail is, I have a tour bike and I did not need to touch the battery.

It was common in the early years of car computer to teach you to always have the battery unhooked, and use ground straps and Blaa Blaa blaa, all of this has fallen by the wayside for the most part. as long as you have the key off, and the negative cable off the battery, you can on most cars unplug and plug in computers with no risk to the unit at all.

If you do not need to remove the battery to get to the ECU, then most likely your ok to leave the battery there.

But it does not hurt to remove it either, your choice.

I have another question concerning fuelpac.I have an 07 FLHRC with the SE hi flo kit installed and modified stock slipons. They might be comparable to SE slipons but I'm not sure. Question is, how do I describe my setup to set fuelpac? Motor is stock. Also I have a 7 yr warranty and don't want to screw that up. Can it be removed if warranty work is needed and Harley not know about it? And finally, will it work with 02 sensors? thx, John

Hi John.
The Fuelpak has a book with it to guide you to the right program.

These programs have been dyno tuned to match the components in that program, so when you go away from that, you can get lost quickly.

Get a set of slip-on that is on your list, modified stock mufflers, without running it on a Dyno, there is no way to know how it will run out.

Hi all. Just got my stock motor, '04 Ultra back from one of the best, local, independent shops around here. Had S & S 510G (gear drive) cams put in. Have been using V & H Dresser Duals w/Harley Stage I package (K&N air filter, SE breather, stage I download and SE slash-down slip-ons), and V & H Fuel Pak prior to the cam change. The Fuel Pak was set up with map FP-0389 as recommended by V & H.

With the new 510G cams, V & H recommended FP-1105. Bike has never run better. No more exhaust popping and backfiring. Acceleration and cruise are as smooth as glass. Extremely happy with the result of this change of cams and Fuel Pak map upgrade. Runs much better than prior to this modification. Just wanted to make everyone aware. No dyno runs were performed.

Cheers,
Dave
