so i installed my fuelpak 2 days ago.
my first ride felt weird at first, popping when decelerating. also the engine sounded and felt weird when decelerating.
then i pulled over to get gas. when i started the engine back up, the idle was really low.
felt like the engine was gonna die.
then the engine check light came on.

next day same thing, engine lights, low idle on and off. then the battery light came on.
engine still didnt feel right when decelerating. felt slightly less responsive when accelerating.

so today, i ripped it out and reinstalled my x14ied leads.

anyone else experienced anything like this?
is it a common problem?
is there a fix for it?

 

we used the fuelpak on my wifes sporty with no problem, and it was there till we sold it.. i put one on my dyna and had popping with it and then finally took it off and went with the power commander 5 and havent had any problems like i did with the fuelpak

IMO the fuelpak is junk for some bikes, but you never know till you try it and have spent the $$ .... i dont think i would chance getting another one

 

I have never been a fan of the fuelpak, but did you load the correct map for your bike? Have you contacted fuelpak about your problems/symptoms and asked if they have another map recommendation?

 

yeah i put the right map in.
i thought about contacting them, wasnt sure how the customer service was though.
iv thought about getting a power commander or a fuelmoto and selling this fuelpak

 

If you call them and tell them your issues, they will have you change some of the settings and it should make a difference. Also search for the fuelpak thread in the sportster section, it has a good bit of info and different tunes to try. One of the problems with the fuelpak is it requires some fiddling with to get it right. I have two of installed on my sportsters.

 

thanks guys, il give it a go

 

bought my bike with the FP on it from the PO. I have had zero issues with it.

give them a call, most posts i see about their customer service are positive ones!

 

My exhause pops now after installing rush slip ons 1.75, looking at fuelmoto micro efi

 

Had a lot of popping with the FP which the PO installed. I just replaced it today with the Power Commander V and it's a night and day difference.

 

The ECM will take several key/run/start shutoff cycles, then should straighten out. I assume you are running the original FuelPak and not the Fp3. Xied's work well with the original fuel pack. V&H suggest it is a good combination. I've been running these for 15000 miles on my '11 Heritage, never an issue.
