Hello all. I need some help with my V&H fuelpac setup.I have E-mailed V&H twice with no responce. I have a 2003 Ultra Classic with stage one,V&H dresser duels,V&H ovals, high flow air cleaner (K&N). The chart says to set at FP-0100. Which I did. It did get rid of all the popping I had, but now acts like you shut the gas off when coasting to a stop. It like lunges back and fourth as if you give it gas then release. It also acts like gas is shut off when shifting from 2nd to 3rd. Any help is appreciated. Thanks, Larry

Hi Larry.

You are quite correct, the fuelpak, to help avoid popping on decel, will shunt the injectors on decel.

It is normal and how it was made to work.

Give it some time, learn to close the throttle as you shift and in no time it will feel normal.

Hi, I have a 04 Deuce, Big Radius pipes, Screaming Eagle stage 1 air cleaner(no download), and the Fuel pak running map fp0007. I am getting a single backfire while starting the motor about 30% of the time. It just pops real load as the motor first turns over, then starts. Anyone else having this issue? I am running mode 23 at value 35 instead of 16 to get rid of the fluttering when the Fuel Pak shuts the fuel off when closing the throttle. thanks

Wow, 35....really? That is quite a bit farther then I have ever heard V&H recommend you take it, but if it's working for you.

As to the pop on start, do you give it a bit a of throttle or do you keep it closed?

SGDEUCE · 08-28-2008, 05:46 PM

Thanks for the reply Jeffytune. It seems you have a lot of experience with the fuel pak. I do not give it any throttle when starting. As for the 35 value, I found that somewhere on the net, not sure where now. If you have a recomendation for mode 23 I would like to try it. Thanks

Jeffytune · 08-29-2008, 12:37 AM

V&H for the most part will suggest going from 16 to 15 to help get rid of popping on decel.

V&H does not put out the info on just what cell does what, but this is gthe one they suggest to adjust to help with popping on decel, and i believe it is the fuel cut.

I would not be surprised to find that the setting of 35 in some small way could be an Issue with your starting.

Hello everyone. I am new here and came across this thread on a search since I just bought and installed a FuelPak. It works great with the D&D Fat Cat 2-1 and the SE A/C. No problems with decel popping and it doesn't surge anymore in lower gears.

V&H does not list a map for the D&D pipes, for whatever reason. I emailed for my map and Derek got back to me within hours to use FP-0881 (which is listed as being for the Thunderheader 2-1). Being the curious sort that I am, I poked through the map listings and had some questions which I composed into an email and sent back to Derek. I am pasting the email in here. Any comments are welcome and I will keep you all posted on what Derek's response is.

On my 2007 EGC I installed the D&D Fat Cat 2-1, SE A/C, and FuelPak no
problem. Bike is running real nice with no hiccups or decel pops. Seems a
little hot still, but that could just be the 2-1 pipes versus the stock
exhaust.

I am curious why I am using the Thunderheader 2-1 map and why you don't have
a specific map for the D&D Fat Cat? I also notice that the FP-0881 map does
not have any values past mode 23 while the map for the Rinehart 2-1 and the
V&H Propipe 2-1 both have values past mode 23. I assume the "newer" version
maps with values past mode 23 are related to the version 12 software, am I
correct? The next question would then be, are you going to create a
specific map for the D&D Fat Cat and would it include values past mode 23?

Sorry for all the questions, but I would appreciate it if you could take the
time to respond. I am very happy with the FuelPak so far, but if it can do
more for me I would sure like to utilize it to its full potential![/i]

turkus403-

Make sure you post his reply. I have an 06 fatty with a fatcat running FP-0511 and noticed that it seems to be running a lot hotter than before. I also noticed that the fat cat uses the thunderheader maps as well. I have tried other maps like pro pipe and it didnt seem to run any better or worse, so went back to recommended map.

I have had my FP on for a couple hundred miles now and do have a couple hick-ups I hope to get fixed. On decel in gear it feels as though it loads up and then surges to get rid of the excess gas. Also have slight ocassional small, small poping back fire . In first & second gear between 2200 & 2700 rpm's it is surging, or slight bucking. It does not do this in higher gears. I am running code from Dereck of FP-1752.

I have a dyno run scheduled for Friday. I am gonna have them do 2 pulls to see what the motor is doing. I am hoping I can email the results to V&H's for a tad better code. I am assuming they will read it and send me a code? How many folks have done this and ended up with a better code?

V&Hines true dual headers
Rinehart slip on mufflers
Ness Big Sucker
Thunder Monster baffle
V&H's FP

Be sure to send along your concerns (Issues) when you send it to them.

What they can do is make minor adjustments to the base program you are running.

As to the pop on shift, it seems that it is inherent to free flow exhaust on Harley's.

I use a 3/8th air impact.

You should take it to your dealer to have the screws removed.

bokephus · 09-03-2008, 11:54 AM

thanks for the tip jeffytune but the brass insert is turning inside the plastic......i am open for suggestions...... i don't understand how the impact will help.....

Narrow Path · 09-03-2008, 10:40 PM

Hey Jeffytune,
07 Fatboy with Vance and Hines Big Radius pipes.....no baffles........everthing else stock.
Need a suggestion on a high flow air filter system (leaning toward the vance and hines air intake and fuelpak) will this take care of my exhaust poping or will I have to reinstall the baffles?

Yes, the brass peice is known to spin out. An Impact could break it loose before they spin out.

The dealer may still be able to get them out.

It's either that, or use a dremel tool and cut the heads off & replace the bolts.
