I'm looking into purchasing after market slipon mufflers for my 07FXDC. I was planning on going with SE Stage I Air Cleaner Kit. I'm not sure of what brand of muffler I want yet. The question I have is, does it matter which fuel management system I go with? Does it depend on the combination of the AC Kit and slipon that I go with? For example, if I was to go with the Vance & Hines Straight Shots Slipons they push using the FuelPak fuel management. Would the PC111 work just as good? I checked out the PC111 website and I couldn't the maps for the V&H slipons, so I'm not sure if that would work or not!! I just want to get the ducks in a row before I spend the money and find out I got the wrong combination. I tried to do search on this subject, but got no where with it!!![sm=headbang.gif]Thanks for your help!!!

Can't really answer your question but try doing a search in the Dyna Forum for PCIII, Fuel Pak, SERT or any other fuel Management system you have been looking at. I know this subject has been covered a lot and there are a lot of threads out there about them.

 

ultimately you will need a dyno to make it perfect. I went with the SERT because I had SE II slip ons installed when I bought the bike. My runs great, no popping . Will get dyno when I go with a new full muffler set up.

 

Yes it matters but no you're not going to get any type of definitive answer on which is best.I have had two, Rev Tech DFO which I hated and the Screaming Eagle Race Tuner which I love.If you're going to have it tuned on a dyno I'd recomend the SERT because it gives you the most adjustability they were able to squeeze 80 HP out of my mostly stock TC88 but people have got good results with the PC3 and others as well.

 

IMHO the PC III has flexibility to work with just about all pipe and A/Ccombinations where the Fuel Pak is more limited, so I would go with the PC III, which I did on my last bike and am putting on the Fat Bob I just ordered. I changed the pipes a few times on my last bike and it was easy to adjust the PC III. SERT is a good option as well but I have no experience with it.

 

Hey....Thanks for the good info!!! I think I know what I'm going to do...I just need to do a little more research! Again, Thanks alot!!!

 

Sorry....My last reply was supposed to be for all you that helped me out!!! I'm still trying to figure out the difference between the"replyand fast reply"!!

 

PCII with Fulemoto.com. I spoke with Jaime he was concise/patient and very informative. I tend to ask too many questions( ****-yzer). He did three set ups for us(buddies) and he was right on with two out of the three so far. Looking to complete the third.
07 FXDL- Rhineharts 2-2 Flushall with K&N A/C
07 Road King Rinehart True Duals with K&N A/C
07 Screamin Eagle Dyna- Jug Huggers still working on it.

Good luck

 

Don,

I installed a Thundermax on my 07. I'm really happy with it. The autotune feature gives me a choice about whether or not I want to have the bike dyno'd. The ECM learns as you ride.

Thundermax is a bit of an investment up front (about $650) but I don't need dyno (avg $150-200) and the system is portable, meaning I can transfer it to another bike if I sell.

The reason I did not go with a SERT is becauseit is not portable. SERTs are married to the ECM you plug them in to for life, they cannnot be moved to another bike once installed. Additionally, SERTs must be dyno'd, the kit only provides software and an adapter. Those were issues for me.

I tried a Fuelpak and it worked fine but I got pops on decel and I probably would have had to have it dyno'd to get rid of the pops (the popswere obnoxious). I have friends withthe Power Commander who swear by them but I have no personal experience.

Bottom Line: The advice you got above about looking around on the ECM forums and taking your time is solid. Read and ask a ton of questions before you buy anything. Make phone calls to the manufacturers and talk to riders in your local area.

I have the exact same bike as you. At one point, in the past, it looked almost exactly like yours too - see pic.

Anyway, this is a discussion and potential argument that there is no definitive answer and/or winner, IMO. As with most mods you consider for your bike, you need to just gather as much info as possible and make your own educated decision about what is best for you. That's what I love about this site - plenty of info with which you can make informed decisions. But, here's my 2 cents in any case...

I've had at least slipons since the beginning (Nov '06), almost. A few months ago I decided to change to V&H straightshots for a different look and better sound (IMO) over the SE II's I had before. I also made a decision at that time to do something about the fuel management. Based on price, ease of installation, and ease of use, I decided on the fuelpak. Another deciding factor for me was to ask myself if I ever intended to go further than stage 1 on my bike and the answer was a definitive NO. I also had no interest in dyno-tuning mine like a NASA space shuttle. I called V&H's tech support to find out more about the product and they told me that fuelpak doesn't work right without a stage 1 air cleaner. So, I found and ordered the a/c and the fuelpak from the same online resource and got them together in one box. I installed them myself and programmed the fuelpak for stock ECM, stage 1 a/c (high flow), and V&H's straightshots. The bike ran great with no popping, etc. Not long ago, I decided to go ahead and get the V&H Big Radius pipes I'd always wanted. Dealer installed and reprogrammed my fuelpak for me. Had some popping on the way home. Checked everything the next day and found they had programmed the fuelpak wrong. When I fixed it and recalibrated the throttle in the FP, the bike now runs great and I have no popping issues.

Anyway, I told you that to tell you this: if you think you'll ever want to go past stage 1 in the future, go ahead and go with a PCIII or a SERT. It will cost you more but the fuelpak isn't really made for that IMO. If you feel the need to get your bike dyno-tuned to get the absolute most out of your setup, go ahead and go witha PCIII or a SERT. The fuelpak is not a tunable device. You are given one fixed map for your specific setup and that's that. However, if you are trying to go stage 1 with a reliable, yet relatively inexpensive, setup, fuelpak is an option for you. I'm happy with mine but I realize and acknowledge that "I got what I got" and I can't tune it any farther and I wouldn't want to use it if I ever want to "soup" up my engine any further.

These pix look familiar? LOL - nice bike.
