XIED's
Well its about a year and a half and this HYPE about the IED's and XIED's...
i havent driven much with the XIED's since winter set in quickly here and on did 1000 miles on my new SG... Whats update on these XIED"s and has any problems aroused by using them ? Any harm seend to spark plugs,,etc.. by using the XIED's on a 2008 with Factory stage 1 download ??

I put 4k miles with them installed on my '08 Ultra and really liked the way they made my bike run. I had no problems and the plugs looked great everytime I pulled them. I do drive in heavy stop and go at least three times a week and they were a blessing. I finally upgraded to true duals and am planning some more upgrade this year ( cam maybe heads ) and so I went ahead and upgraded to the ProSERT.
I think you will appreciate them. They are not a silver bullet and my bike still got plenty hot, it just wasn't to the point of burning the skin off my legs anymore!

I tried the Xied's and my '08 UC did not like them...sort of the "one size fits all" solution.
Like many others, I then decided to go with a more full-featured tuner...much better performance.

I can't see value in IED's for anything other than a stock bike unless you take some steps to control lean AFR's in open-loop mode. You could add free-flowing mufflers and AC, do the HD Stage 1 download, and then add IED's--but for the money that costs you could buy a PCIII or PCV, and that's a much more flexible and effective option.
I have never installed IED's because I wanted more out of an EFI controller, as their scope is very limited. If you buy a PCV from Fuel Moto you will get an accurate map for your setup based on a dyno-tune of a bike like yours. That will affect the AFR range previously affected by closed-loop and open-loop. There is a misconception that removing the O2 sensors from the equation is somehow reducing control, but this isn't true. In open-loop mode with a PCV attached the ECU is capable of compensating for temperature, humidity, air density, and barometric pressure. The narrow-band closed-loop system employed by HD is little more than a means to meet EPA regulations, not as a method to accurately control AFR's across the board.

The above explanation is done well just to show an example of Dyno proven, the Red is done with Stage 1 Xieds .. definitely cooler and better running than stock, the Blue is after the PCIII Tune ...
