Hoping someone can help out here. Got the American Customs full exhaust this past weekend (factory header and mufflers with cat removed and different baffles). Overall, very satisfied with sound, performance, and price.

Was told by them that there is no need for a tuner or stage loaded because the new bikes have a "closed loop" system that tunes itself as you ride. However, since putting the exhaust on, I now have hesitation (like a long hiccup) right around the 2,000 RPM mark. Sometimes it is a little before 2,00RPM and sometimes after. The bike is smooth around town under throttle but when cruising on the highway, this hesitation is very noticeable if I am around those RPM's.

My question is would a Stage One download fix this? What exactly comes with a Stage One? I hear it will cost around $150. Does this come with a new A/C? I see the black backing plate is removed with a Stage One. Or should I go with a PCV or SERT (or any others)? I had the SERT on my Deuce before with a Heavy Breather and it was awesome, but only after the $1,000 it cost for the SERT, Heavy Breather, and dyno tuning. I'm trying to avoid that this time. Do you need a Stage One or will a Tuner/Controller work? A/C come with or separate? Should I even worry about an A/C? I tried to send Jamie at Fuel Moto an email but haven't heard back.

I get so confused when it comes to these controllers. I here about autotuners, XIEDS, PCIII, PCV, SI2000, PowerPaks, etc. Looking for the best, most efficient way to go.

See how confused I am? Thanks in advance.

 

i use XIEDS, but they are most effective at cruising speeds, if you have a hesitation at 2000 rpm on your way up then you may need another solution.

pipes are cool, but to get any performance advantage you should open up the intake- i prefer the ness big sucker, it's about $115 shipped on ebay from easternpc- that's the chrome version which complements the chrome highlights on your motor.
It is a 30 minutes tidy install and does not require removing the intake brace as some others do.

( just uncorking the intake and exhaust should be good for 7 to 10 horsepower---, the exhaust alone ( as you have) still has the intake restricting how much air can get into the motor)

once that is done if the motor is running smoother, then XIEDS ( $125) would probably be suitable--- other than that it's the world of tuners, which I stayed away from.
There are posts everyday from guys have one problem or another and my Pals with "piggyback" tuners always have problems with MPG/Emissions/ low range/high range or something, it's always something.

and you already have experience with the HD download.

I just responded in the other thread, but I'll say the same here.

Bull$hit.

Your ECM can adapt a bit based on things like changing airflow and varying fuel quality. It will not compensate for a new exhaust or air cleaner. When you change airflow into or out of the motor, you need to make sure your VE tables are optimized for the actual parts on your bike.

To get the most power and efficiency from your engine and the parts you paid for, you need a tuner. You then either need to pay someone to tune the bike, or you need to learn how to do it yourself. Canned maps (regardless of the source) can only get you so close.

XIEDs are not tuners, all they do is fool the ECM into thinking it needs to run richer. This does nothing for the VE tables and will not solve the problem, nor will they compensate for the increased airflow of a Stage One.

 

Thanks Train - that answered a question I was tossing around. I can't afford a tuner at the moment and am using a canned map but was tossing the idea of XIED's around. Guess I can toss the idea out and save up for a tune. Sort an on-topic hijack:

If you ask a tuner "I'd like better mileage" or "My bike is running hot" do they custom tune for these requests or just for the hardware you have installed and cooler running/better performance is a a result of the tune?

 

Tuners can tune for mileage or performance; which do you want? Either way, the motor will run cooler.

Sound like you are a candidate for a DIY tuner if you want to avoid the expense of dyno tuning. If you aren't planning to upgrade beyond Stage I, you really don't need to spend the $$ on one of the more sophisticated tuners like SERT,TTS, SEST, PCV, etc.

Check out the Dobeck/Techlusion DFO/TFI; similar to V&H FulePak but way better.

About $245 but you can pick them up, new or used on Ebay for less.

If you did a Stage I upgrade on a carbed bike, you would not go the expense of replacing the ignition module with a programmable ignition; the stock ignition curve will work fine with a Stage I upgrade or even with a mild bolt in "mouse" cam.

No different with EFI; just need an electronic jet kit to get the AFR right. The Dobeck system is load based as opposed to throttle position like the others. Easy to install, good customer service and you can tune the bike to your liking; for mileage or performance.

 

Some tuners are not true tuners, all they do is fool the ECM into thinking it needs to run richer. Tuners like the Power Commander V do this. A true tuner would be along the lines of a TTS Master Tune.

Just go with the Xieds, I bet that will solve your problem, but make sure you get a free breathing air cleaner too, or cut open the stock one, you have to let more air in.

 

No it won't. All the XIED does is send a different voltage from the O2 sensor leads so that the ECM adds more fuel. It richness the mixture only, it does nothing to compensate for the additional airflow.

The issue the O.P. is having is related to his VEs, not his overall Lambda.

 

I have used this type of fuel management and it worked quite well..the only thing I didn't like was you can not raise the red line like you can with some of the other more sophisticated controllers....but if all you want is to make you mostly stock (stage one) bike run about a zillion times better than it did when you bought it, this is the thing to get (there are several company's that make them so you might want to shop around)..

 

Why worry about raising the rev limit from 5800 to 6200 on a touring bike?

No need to shop around. Mark Dobeck founded DynoJet in 1997 after many years working with this technology and has been the industry leader for many years. Most other controllers are throttle position based and not load based; load based is better.

The XiEDs are what they are ane will cool the engine down but ony work under light load, i.e, idling and at cruise; no substitute for any type of fuel management system.

I forgot to mention that the OP does need to install the SE A/C to get the full benefit of the fueler.

 

Talk to Jamie.
