I have them on my 07 RKC for a year now. The best investment for your 07 and 08 96 engine, runs cooler and better throttle response. I got the EIED's AFR is 13.8.1 convert stock exhaust to true duals with K&N filter and get even better result. Since I've done that I seem to be able to rev up higher between gears without the engine sounding like it's working hard.

Steve's website is here http://www.nightrider.com/parts/
I have the xieds on my 08 and they work great, much cooler motor and more responsive all around.

I have been looking at his sight. Lots of information on these that goes along with the talk on the forum. I think these are what I will go with. And from Nightrider!
Nightrider rocks. I would like to say thanks to them for the support given to us on the front lines. The discount is... well, I will just say thanks.

XIED's
OK, even though I really don't have a clue what the best way to achieve best performance, mileage and heat reduction is after reading all those threads.....I went with XIED's only on my 2007 EGC. Nothing else modified...the bike definetly runs MUCH cooler, now the downside is I noticed no real performance gain and I'm still below the average posted here in mileage at 37-38mpg!
Anyone else getting this poor mileage?

The XIEDs make the O2 sensor operate mostly outside its linear band. Don't be surprised if you use them and experience undue fuel usage and/or trouble codes.
The standard IEDs take the fuel ratio to the lowest possible recommended level for reliability concerning the O2 sensors.
Here's an excerpt from the Screamin' Eagle Super Tuner (replaced the SERT) manual:
(emphasis mine)
These devices are merely an external means of adjusting the Closed-Loop Bias table.
The ECM fuel tables use 14.6:1 AFR as the key for closed-loop operation. 14.6 - 0.5 = 14.1 which is what the standard IEDs shoot for. Of course, if you have a SERT or similar already in service, you can do this yourself internally to the ECM. Also consider that it's assumed the factory or stage one downloads use a closed-loop bias which actually shoots for 14.6:1 from the get-go. If for some reason it's already biased toward richer operation, using any of the IEDs can/may take the sensor out-of-range.
If you have a completely factory-equipped bike, either totally stock or all H-D parts with appropriate stage one "download", then the standard IEDs can be a viable alternative to other more costly (though capable) means of making your riding experience a little more friendly.
If you have other breathing parts installed, please look elsewhere to correct your fueling requirements. None of these devices are what you want to be using. I've explained it in painstaking detail in that other thread. Multiple times.
If you use the standard IEDs, look for a reduction in mileage of 3-4%, or from 40 to 38 mpg.
If you use the XIEDs, look for a reduction of about 6% (minimum, on a good day), or from 40 to 37 mpg.
The standard IEDs take the fuel ratio to the lowest possible recommended level for reliability concerning the O2 sensors.
Here's an excerpt from the Screamin' Eagle Super Tuner (replaced the SERT) manual:
Harley-Davidson Motor Company started using O2 sensors with the 2006 EFI Dyna models and today all Harley’s use O2 sensors and can operate in ‘Closed Loop’ mode. Harley uses what is called a narrow band or switching sensor which controls over a very narrow range that is near stoichiometric (14.5 AFR). In some circumstances the tuner may want to move this control point, and the ability to do this is accomplished with the Super Tuner by adjusting the Closed-Loop Bias table. This table will allow moving the O2 set point by about ą 0.5 AFR. Trying to skew the set point by more than ą 0.5 AFR causes the sensor to become inaccurate.

08 R/G with XIEDs, SE heavy duty breather, and Rush
slip ons with 2" baffles....
Riding 2-up I'm constantly getting 46 - 47 mpg on 2 lane
highways traveling 60 mph
Very happy with the results I'm getting

Kight Rider has said that both the ieds and the Xieds do NOT work correctly with the '09 FLH models. I don't know why and he didn't say. Since the ieds are basically just resistors, I'm not sure why they wouldn't work....I have no idea how the Xieds work!
Does anyone know if the ieds still work on the '09's?
Thanks & cheers, geeded

My Indy rebuilt me to a 107 with the SERT and the torque and throttle is amazing. The top end is much more than I will ever use.
You have to find someone who really knows how to tune. If you are withing a day's drive to Philly I have the guy for you.
