Back to thereading that you replyed with,how did you get 850mv?

 

Not quite Donny. The 02 sensors just relay the message back to the ECM. The 02's never change anything. they just transmit back to the ECM. There is a cold part of the map that tells it when it's not at temperature. Richen's it up till the temps come around. IF you had a SERT, this cold start part of the map can be adjusted as well.

It leans out as the temperatures come up, it reads partly what the 02 sensors are sending back. When it gets to 14.7 the ECM stops. It always starts out rich on cold starts. Just like a choke. Less air more fuel till the temps come up and then you have to add more air.

The other end of the map is the EITMS ( Engine Idle Temperature Management System) Page 140 on the touring owners manual. When it gets too hot, it shuts off the spark and fuel to the rear cylinder. Richen's up the fuel to the front cylinder (like cold start) and the rear cylinder becomes an air pump. Cools the bike down at idle.

The IED's just knock it down .5. As far as the ECM see's it's at 14.7 when in fact it's really 14.2:1. Steve has tested along with Rider57 that 13.8 is about max on the narrowband sensors. They can explain that part of it and have the lab tests to back it up better than I could ever do.

I can however maybe help you with an example in laymans terms. It's always easier for me to relate it to something I know.

Putdifferent sizedtires (IED's)on your car/truck. The speedo is the 02 sensor. Cruise control is the ECM.

Crude, but it works for me.

 

I'm not sure why this became a battle of who knows what, or more, than the other guy. Cruiser, Rider, Heywood, and others have provided a wealth of practical and technical information to those of us who lack the same. Practically all of us who have tried and used this product have been pleased, if not thrilled, with the results. I'm not sure why wmw has chosen to antagonize some of us and question the results that we've all experienced first hand.
Wmw, if you've tried the IEDs in any form and are displeased, just say so, and tell us why. If you haven't tried them, then IMHO, you've got nothing further to contribute to this thread. Many riders are benefitting from the exchange here and if you've got nothing to add from your experience with them, then just go away. I'm not a mechanic or an engineer of any kind, I'm just a paramedic with 30 years of street time whose scoot runs better. Now if you want to discuss pathophysiology and pharmacology, I'll start another thread and invite you over.

Heywood,everything you said makes perfect sense to me, (except the cruise control and tire analogy, lol) just kidding. I still don't know why the o2 sensors don't change voltage, when they're in what the computer thinks is a rich condition,,,,ah crap, I think I answered my own question with the question. Well, the comp thinks it's 14.7, when in reality it's 14.2, but the o2 sends the signal for a rich mix through the ied that drops the voltage and becomes 14.2,but the compTHINKS it's 14.7. I get it now[sm=bangbang.gif]

 

I have read this thread and am convinced that the IED are the way to go for a cooler engine and better performance. Essentially, it seems to me that the IED is simply stated a biasing circuit: it simply changes the calibration of the O2 sensor to permanently run the air fuel ratio that much richer. What could be simpler! I am picking up my new 2008 FXDC in a couple weeks and have to ride it 200 miles home. I don't want to run this bike lean during break in and wonder if I can install the new Xtreme O2 IED in the dealer parking lot before I take off. Does anyone know where the connectors are located on the Superglide Custom and what tools I will need to take with me?

 

Ty-wraps, a screwdriver for the seat (phillips head) and a 3/16 allen wrench with a long handle.
The rear connector is under the seat and the front is behind the voltage regulator between the downtubes.

My DYN OiED's for my '06 are on the way!

 

Donny....

Yup, you got it. That's exactly how in works in a nutshell.

Upnorth.....

It's a good idea. I did the same thing. Just maybe do it around the corner...lol. Take a look at my pictures on page 23 of this thread to help you out on the XIED placement. Another place you can look is the video that Steve did on "How to Install the LC-1's" The first thing the video did was show where the connection break on the front cylinder was. This was all I needed to get me started on what he was talking about. The rest of the video doesn't apply, but where the disconnect did.

I usually take mine off when I will take it in for warranty work.What a difference that ride is. That's when you find out how dramatic the change is. Getting use to them is nothing. Riding without them is the last thing I want to do now.

Further along in the video, it shows where the rear connection might be. Mine was wide open (due to the different pipes). The video showsLC 1 installon a Road King.

mikeurig...

That's great. I hope it works out with the Dyna. Are you the guinee pig for the new OiED's? I'm pretty sure they'll work perfectly. From what I know of Steve, he won't send you anything unless he's confident it'll work. He and Rider did some nice work figuring it out. Let us know how it works out.

 

Guinea Pig??? Hmm, I guess I'm going to be a guinea pig also. I have an '06 Street Bob with V&H Big Shots, SE A/C and HDdownload. I haven't been on the forums for awhile, and when I logged on and started reading about this product, I couldn't wait to order a pair of the 06 Dyna IED's. They've shipped andshould be here any day. If they perform as expected, I will be VERY happy. Sounds like just what I need to cool the bike off a bit and reduce decel popping. Willpost on the results.

 

TheO2's can't adjust. They just generate voltage according to the gases. 1volt is the norm. The IED adjusts that to around .8 volts and that is what the ecu sees. The O2 can not put out more that 1 volt.

 

BINGO! but dont tell wmw, ok?
