Roadking, are you saying you went with true duals and the XIED's only, no other fuel mapping needed?

 

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.

 

Try this thread...a looooong discussion of the pro's & con's...read the 1st couple pages, then jump to the end for about the last 5...you don't want to read all 2000+

wow... My head hurts. Way too much info. Any long term users have trouble or failures of the Xied?

 

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.

 

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.

 

None of them work per an e-mail I received from the owner.
