I'm not up on the V&H's fuel pack but, wouldn't the IED's basically doing the same job as the fuel pack??

Would one cancel out the other?

I think he's right. If you go with the stage 1 w/o the download, it would make sense that the bike would lean out to 15.1. The download changes the VE and/or timing to bring it back to 14.7. So putting the IED's in tricks the ECM into thinking that it's still at, say 15.2 and dumps more fuel to it till the 02 sensor tell it it's at 14.7 when infact it really is at 14.2.

In the mind of the ECM. It doesn't know about the IED's. It still thinks it's got a direct link to the sensors.

 

ToBeFrank:

Thanks for the reply. You pretty much confirmed my thinking. I think I will keep the stock A/C and the IED'sfor now . When I get a chance, I will remove the IED's, get the Stage I download. Then I will reinstall the SE A/C and the IED's.

For the riding I do, I do not plan on any additional mods, so I am pretty sure that route will work satisfactorily for me. I see no reason to spend the money for another dyno run with the stock A/C just to prove a point.

 

Mr Clean great experiment. Speaking of the stock airbox. Too cold here for me to ride. I have a '07 FLHX with the IED's. Can't wait to try them out. I emailed Nightrider and was told that they recommend using the IED's with the stock airbox with a k&n airfilter element. Joe Minton wrote an article in American Rider a few months ago saying that the stock airbox makes more tourqe in the midrange vs the s/e a/c and that the s/e a/c makes more top end hp. I have the stock airbox with a k&n filter with stage 1 ecm download. I will see come this spring.

 

You guys are getting there. I have been running the 2 LC1's on my RG for quite a while. Temps are way down, 340 to 210. Here in the mountains at 10000 ft we are lean to say the least. They work for me. before getting the LC1 conversion, I figured out the resistor values nnede to get about 14.1:1 AFR ( 12K and 25K). They cooled the head temp down by 40 degrees. Great work guys. Your gonna like like it.

 

Rider57,

The Nightrider O2 IEDs uses 20k OHM and 10K OHM resistors. 25k and 12k is pretty close. Also what temps are you refering to?

 

Can any body tell me how long the ied's are from plug end to plug end? Thanks.

 

Approx 6 inches end to end

 

fastbagger: What is the part # for the K&N filter you are using in the stock airbox?

 

Here it is

Exhaust temps at the head or about 1 to 2 inches down the tube. I have a background in electronics and started with a decade resistor box to experiment with the idea that the output of the O2 sensors are voltage and knowing the input range to them does not leave much in the way of analog signals (voltage) to play with. The original values I used gave me the best results but I found that they also provides too much load for the 0 to 1 volt range. The 25K and 12K values I used first made the AFR too rich. Next I tried values of 22K and 12K. This gave me the AFR of 13.7 and that is where the current value is staying until later today. This is my second bike I am "playing " with. The RG has the LC1 kits installed and programmed with LogWorks. I runs perect for me and my habits. At idle the AFR is 13.0:1. Off idel to 20% the AFR is 13.5:1 and above 20%TP it is 13.7:1.
I did reprogram just lastnight for the above values.
Keep in mind as I am sure most of you do, every engine is different. My altitude is also at 4800 ft which makes a difference.
I about 2 hours I will have tested the 20K and 10K values and see what that does at this elevation.
