Xied's Question
#22
#23
i ran xieds for a year on my 07, just slip ons(with the a\c they didn't cut it)they were a slight improvement over stock still got too hot and would start pinging,with the a\c ping was just as bad as stock.went to a pc5 huge improvement all ping gone and runs cooler.not saying pc5 is the way to go,but saying a tune with any tuner is far better than xied.

Ok
Peace

Really, he is not off track and is just being very informative, hard to dispute anything he said. It's fundamentally wrong for someone to come on here and try to convince people the XIEDs are the cure all and you'll never need a tuner until you do engine work, just like it's wrong for guys to come on here and say you always need a tuner.
But I've got a good bit of experience with IED's/tuners and before them, carbs, jets and timing. I see absolutely no reason to spend money on a tuner on a stage 1 or stock bike.
I find iClicks argument pretty funny considering it is basically opposite logic to the argument he uses to support his cams.
When defending his cam choice the argument is most riding is done at low throttle settings and low rpm. But his "problem" with XIED's is that they only help at low throttle settings and low rpm (relatively).
His second argument for his cams is that they can be purchased for cheap used, yet he advocates an expensive tuner solution in place of cheap IED's for a stock or stage 1 bike?
whatever...

He is not only off track with the op's question,. he's wrong with some of his info. I don't know why iclick did this post? He know's that I as well as other's on here run full Stage 1 setup's with Xied's and get good result's. I've run them with a 2into1 catless header and powertube muffler. I'm back to a stock 2into2 header w/cat and modified stock muffler's. My gas mileage only dropped 2 MPG with the Xied's. If he knew what he was talking about, he would know they also effect the open loop about 5%.
Check the fact's!

IED's are a perfectly good solution for bone stock bikes that are running lean from the factory. They also are a good solution for bikes with high flow A/C's and exhaust.
Are they the only good solution? No. Are they the most cost efficient for most people in most circumstance. Probably.
BTW, regarding Dyno runs- I use a Dyno to run thru the gears at cruising throttle settings. With the sniffer you can tell what your AFR is, as well as identifying any flat spots in power/torque.
The typical WOT Dyno run is interesting, but not nearly as useful as the info you can get cruising thru the gears on the Dyno.
Last time I had a bike on the Dyno that had X14iED's installed, along with a Hi-Flow Air Cleaner and free flowing exhaust the AFR stayed right at 13.85:1-13.95:1 all thru cruising acceleration (NOT WOT) thru the gears. Power/Torque was a nice curve. Hard to get better than that, especially for $100.

I'll try to address each comment made about my reply one by one. FWIW, I replied not in response to the OP but to some comments made thereafter that I felt might misrepresent the operation of IED's, I assume unintentionally. I tried to make it clear that I think they have a place in the market and can work favorably for some people.
I don't mind someone disagreeing with my ideas on tuners, cams, or whatever--as an intelligent and friendly debate is good for everyone. But the "other forum members" who made the claim that I trade favorable feedback for products from FM are lying. I have never "shilled" for anyone and will never do it here or anywhere else. I'm frankly disappointed that anyone would make a statement such as this without foundation or any evidence, as this is the first time I've heard it. I promote FM because I feel they do an excellent job and sell quality products. Please, let's not stoop to tabloid gossip here.
I believe I said they had a niche in the overall market, didn't I? I also tried to make it clear that I was not bashing them. Could you list the info that I provided that is wrong, as you didn't mention anything specific? Thanks in advance, as I'm here to learn.
Could you explain how this works? They work in line with the O2 sensors, so how do they affect the bike's operation in open-loop? It might seem reasonable to think that there would be some carryover from closed- to open-loop mode, like when you roll-on the throttle and pass from one mode to the other, but since the ECM cycles many times per second I can't see how this effect would even be measurable, much less something you could feel. Please explain how this works and how the 5% figure is calculated. TIA.
This isn't the same phenomenon at all, and isn't even close. The IED's improve part-throttle response a bit. The SE255 cams improve the low-end and mid-range considerably, and this is manifested at part-throttle and full-throttle to a much greater degree than IED's can provide. I've ridden my bike set to 13.0, 13.5, 13.8, and 14.5 (current) in the cruise range and I can tell very little difference in part-throttle response between these settings. I also have seen little difference in cooling while cruising, but mileage is affected considerably--about 6mpg between the richest and leanest AFR settings. YMMV.
As a frugal kind of guy, when I made my cam selection I bought them for the lowest cost possible for the effects that I wanted and received. When I've purchased tuners I've done so at the lowest cost possible for the features I wanted and received. All tuners I've purchased have come from FM because they sell at a deep discount and provide excellent service. There's no inconsistency here at all.
Lord, I'm so misunderstood on this thread. Now did I say anywhere, in this thread or any other, that the Stage 1 download changed the AFR? I appreciate other points of view about this or any other subject, but please don't put words in my mouth. Thanks in advance for your consideration.
Now, about the Stage 1 download: It doesn't change AFR, but it does adjust for the addition of free-flowing AC and mufflers which change the airflow characteristics of the engine. The VE values (projected airflow) will change whenever hardware alterations such as these are made so that AFR remains the same, so there are adjustments made other than timing. How much change is made and where varies considerably according to the year and model.
If you'll dyno your bike or measure Lambda (AFR) in some other way you will probably find that your AFR's are not what you may think. Just because the ECM has "12.8" shown in the 100% column of the AFR or Lambda tables doesn't mean it's actually running that mixture. Try it. What's more, the transition areas between closed- and open-loop, as well as WOT, can spike into leaner-than-optimal conditions when a stock tune is coupled with Stage 1 hardware changes.

It only changes the timing tables. Fuel remains at 13.8:1 mixture up to about 65% throttle, then it goes full rich, 12.8:1 above and beyond that.

Have you used them??
