Has anybody tried these on their 07/08 Dynas? The site says they are true 'plug and play' and will richen the mix to 14.2:1
http://www.nightrider.com/parts/o2_ied_installation.htm

Sounds like a good deal for about $70.00

Nightrider seems like a decent company, wonder why I haven't heard more about these. Any info appreciated, thanks!

I just bought a set for 69.99 shipped.They were on sale for bike week.I don't have em yet but since I live in Az,can't hurt.Regards,Tom ps:I have a stg 1 download,SE Hi flo A/C ,V&H TruDuals w/FuelPak on my 08 Ultra & she runs real good.If theEnrichment resistors don't help,I'm only out $69.99

This is kinda like the thing made for my Dodge on the AIT (Air Inlet Temp) sensor. On my truck it also has a resistor in the wire, fooling the computer into running a bit richer cause it thinks the inlet temp is cooler. Since FI runs richer when its cooler, this thing just makes the computer "think" the O2 sensor is still cold. Of course, guys on the dodge forum got wise, got an ohm meter and measure the resistor in the wire, then started making their own. Im pretty sure we could make our own as well. The one we made for the truck cost about 7 bucks. This might be a great under $50 mod, if figured out.

But, if you have a fuelpack, why do you also want these? Does'nt the fuelpack settings richen up the fuel mix? Guess I'm confused???

dklozik; makes sense..anybody got an ohmmeter read on their o2 wires? very interesting idea. thanks.

I put a set on my stock 08WG. I'm very happy with the result. I believe they do the same thing a sert does if you max out the O2 bias tables. I would not use them if I ran an open loop fuel management system.

I plan to put them on my wife's 07 sporster.

OK, one good report! How did you know it made a difference? More power/acceleration?

I can't really judge power or acceleration by the "seat of the pants". I can judge an engine that has a slight lean surge while cruising. The O2 IEDs made my engine run smoother while cruising and stopped that lean "ragged-edge" feeling. Kind of like rasing the needles one groove back in the olden days without changing main jets.

When I change air breathers I may just go with the stage1 download and keep the O2 IEDs.

nice find. I think that would definately be worth a try.

Hi Labfreak(and all others on this thread)

Just remeber that you only adjust the "closed loop" fuel for example if you twist the throttle wide open it goes in the "open loop" and uses the fixed map so this is only sorta a stage 0,5.

The fuel pak on the other hand dont rich up the closed loop only the fixed map (if you rich up cruse mixture the lambda value going to lean it out anyway)

But if you use the enrichener and a fuel pak the fuel pak adjust the fixed maps and the enricherner fools the lambda/ECM (havent tested this but in theory it should work).

I tested these enrichernersfor about6 month before Stephen released them on the market and they are in my opinion good for using a more open exhaust but not the stage 1 air filter .. above that the fixed map is to lean.

Nice hearing from ya!

Kricke, thanks for the input..why not with the stg 1? Don't quite get it, if'n yer wanting to richen it up??

Will they work on an 06?? Seems like they should.

You said that the Fuel pak only richens the map....Is this true with all fuel management systems?

Would there be any benefit to using the IED with a Tmax/autotune system?

Hi all

First I have to say sometimes my English isnt perfect! (I'm a swede (and yepp I know what swede mean :))so just ask me about the strange words that can pop up here...

On Lab freaks q: I referd to only using the enricherners and stage 1 slip ons and air filter whit out the H-D download. if you have a stage 1 download yes it would be just fine. but if no download WOT and fast up rev. of the engine (i don't now the real name for it but you probably know what i refer to) there will be to lean mixtureif you let in more air due to "better" air filter.
But you are in the OK area wthout the downloadwith onlymild open pipes (SE slip ons or equal BUT not drag pipes) but not the air filter.

Remeber that i live in Sweden and on a really hot summer day we are not quiteup to the same tempcompared to anormal day in texas so this needs to be in the calculation on my answers..

On JEFX q:just differ onwhomakes them...
SERT: you have the Lambda bias so you "fool" the sensor in the program.
Race fueler: only to fool the ECM signal to the injectors and when going in to cruse the O2 sensor will back the setting as far he can to match the 14.7 value.
Power commander: uses sensor blocks (remove the sensors with resitors on the sensor cable).
Direct link: approx the same as SERT.
Havent tested the autotune but read about it and it uses lambda values and its changeable so yes you can change the "idle/cruse" value.

My choice is the SERT onmy Harleybuton my fun bike have a Direct link (Buell XBs).

//K

"buton my fun bike have a Direct link (Buell XBs" Have you run out of fuel on your Buell Yet.... LOL ... There a pain to reset ... 5 miles at 45 mph in 4th gear to reset .. PITA ..LOL

:Dtried that and got the t-shirt... actually twice (I hatesmall tanks).....

You missed my point ......Has nothing to do with the Tank size only the direct Link and how you have to reset it .....

Ahhh I read it to fast,,,,

I borrowed the scamalyzer from my stealer and after a TPS reset it was on a dyno for a couple of hours so i didn't reallycared.
I hardly use the cruse mode on my Buell, it's a race bikeso the steady run style isn't my bag LOL....

LMAO ... Some of the other Tuning devices will do the same thing and they don't even realize it..LOL...They think it's running fine... LOL....But that what keeps me in bussiness.."Only POP'a every now and Then" ... LOL

yes,not many bikers can feel +- 5hp/10ft-ib. So thenot sonice hole in the wall typetuners can sell a tuning device of the shelf, load a std. map and then charge a bunch of cash (practically the same as a stage 1 download) and the customer is still happy...

The Buell was sold today! (sobbing a little) to finance my new project.

My -08 Street Bob is planned to be dyno tested in phases:

1, orignal with about 1600 miles on it (1000kM)
2, stage 1 with K&N/SE filter and Bub Reinhart 2-1 with my one "high tourqe"baffle
3, mild ported heads (clean up)
4, cam (going to test a bunch matching the mild port)
5, 103" flattop pistons
6, larger valves,better valve springs, more porting job
etc.
etc.

To see what can be done on a specific budget and what to expect..

But as always everything is in thepants of the beholder, I just don't wanna see my net biker friends going to spend a fortune on things that don't really works as they want and in the same time may ruin their bike (the commercials/tech info on these"miracle devices"area bitfuzzy andnormally promise more than they can deliver out of the box).

//K

Thanks for the info Kricke. Lookin forward to the results of your new project!

OK, Trotter and Kricke, you motorheads!!!:DSo, what's the verdict, in laymen's terms, are these IED's $hit or should we try 'em out? I have stg1 download, hi-flow A/C and Cycleshacks slip-ons.

BTW, Kricke, I relate well to swedes! My grandpa is from Jarvso!

Labfreak, I would recommend them for you. The stage1 download fattens up the open loop part of the fuel map (cold engine, 50%WOT and above). The closed loop section of the map would still be at the 14.7 AFR. Using the IEDs you could fatten the closed loop section to 14.2 AFR which would help with a fully warmed up idle and cruising down the highway.

If you had a sert, you can do the same thing as the IEDs by increasing the closed loop bias voltage. Since you don't, then the IEDs are a good idea (IMHO).

Yes, they are a good cheap engine investment and the work good but not as amiracle..

I'm not trying to put Stephen out of buisnessby saying it is not hard to make these your self, of course with out the plug and play feature. But for a couple of hobby hours in your garage and resistors for about 5$ (small guess compared with my cost here in sweden for four small resistors) you all with the thumbs attached right on your hands can make your own enricherners...

I can't figure out how to publish a picture on the schematic of this "device" but if some one wants it and can publish it here(I have permission from Stephen to use this in forums)..

OK, not sure what 'not quite enough' means..probably not rich enough? But looks like these might work out, thanks all for your help.

If you dont plug in the O2 sensor "block" that comingwith PC3 the answer is yes (the PC3 is like the SE Race Fueler and fooling the system after the ECM)

I went ahead and ordered them, $69.99 seems like they are worth a try, I'll report back after install, but will probably take it to the techncal forum, thanks to all for your help/knowledge.

BTW some folks are geting some good results with these IED's over in the Tech Forum:

I dunno, if you got a PCIII maybe IED's not needed as it sets all that stuf up. I get the impression these are kind of a poor man's SERT, PCIII, or wahtever, they richen the fuel mix is all by increasing resistence (Ohms) at the O2 sensor is all, but, from what the technical guys/gals are saying, they work pretty good, especially by heat reduction.

Dynabob hmmm if the engine light comes on after warm up I think the O2 sensors are disconnected or the blocks from PC3 arent in place or have bad connection. check thefault code andpostit here and I'll help you find the answer...

And on your question if to replace PC3 for the enricherners i would say no,in my opinion get a god dyno setup and your be fine or if you are up for a little testing get the enricherners and plug them in after the initial PC3 tune so you use the closed loop feature again.

I can't help you with a dyno run (I live in Sweden so...) But surley some of the guys/girls here should have the right connection to a good localtuner...

//K

I forgot to say I have the power commander EX
so no eliminators on the O2 sensors......it uses the O2 for EPA approved....

thats why I was wondering to add the IED with my PCIII EX....

how do I get codes without going to dealer....

OK, I'll see if my bad english can explain....



Make sure run/stop switch is set to run
Press and hold "trip reset button"
Turn ignition on

then you should be in diag. mode and you should see PSSPT (not 100% sure on the letter combination on -07)in your speedometer

press trip again and the first letter start flashing and if you have any fault there should be visable (go thru all letters with same procedure)

write down the code you findthen press and holduntil a verification that you cleared the fault code...

I have aflow chart thati can mail in case of total confusion ; )

I had an SE Race Fueler on my 06 bob. It ran much betterbut no matter what I did I kept gettingtwo codes, rear cylinder rich and rear cylinder lean. I had the two dealers check it out and they said everything was fine and that this was common on the Race Fueler. I think it's the nature of the beast on the O2 equipped bikes. I ditched the Race Fueler and went with the SERT. No more codes and it never pops.

I still have the Race Fueler if someone is interested in taking it off my hands. PM me and make an offer. The Race Fueler is good for someone low on cash (which I was at when I bought it). But I saved up a year and went with the SERT and am completely happy.
Sorry for the shameless plug;).

Figured out my rear O2 sensor was the prob code P0154
so looked at connector and one side got pushed out when reconnected....

so no more code.....

thanks Kricke

So, for a stock intake and only a set of slip-on pipes ('07 WG with Krome works 3" HPs) will this device do anything for decel pop? Also, it would be interesting to see a dyno comparison before and after, with just pipes and stock air and fuel management. I'm a cheap bastard, just wanna know if it will do anything I can hear or feel. Also, any change in MPG.
Tim

I'm glad you find the error...

I did my home work on your PCEx and yes it would be smart thing to use the enricherners because of the "grayed out values" you can't adjust , BUT I really want to advice you to do a serious dyno setup..

//Kricke

fastfxrs

There arent any major hp/Tq changes in closed loop going from +14.7-1 to 14.2-1, but you will probably feel the engine going smoother and not as hot as before (it was this purpose these devices were built for).

You will burn more fuel (you are richen the mixture so....)

Small tip when using stock headers: is that the crossover tube is pushed quite far in the front pipe.
So I took a hole saw (as big i could get in the pipe) lube the pipe up real good, then saw of the intruding crossover end(mayby intruding not isa english word ; ).

Quite common mod on the baggers Y-pipe to gain 2-4 Hp and and get a cooler engine due to less restrictive header..

Thanks Kricke, good advice. Do both ends of the cross over tube extend into the header pipe, or just inot the front pipe?

Kricke,
You speak better english than most Americans I know.
And yes, intruding is the perfect word for the obstruction. Makes you want to go kill it.....

He he yes if you have a "curved" hole saw you can do the rear pipe,, naa just pulling your leg here...

If you look on the crossover fittings on the rear headerthere is another type of mount welded and as far it wasin my "old" wide glide -07 pipe there weren't any obstruction (learn't a new wordfrom KK6Pg) to worryabout.

ha ha yepp I thought about an intruder and then bend the word a bit...

Installed my IED's today and took a ride,can't say I actually FEEL any real difference;smoother? maybe, and the engine seemed not as hot when Ipulled into the garage and shut down.
They are easy to put in, I had never looked at the front caddy so it took me some time to see how that came apart, the rear was a snap. I'll get a laser thermometer on it soon and see how the temps compare with what they are finding on the tech forum.
Thanks Kricke,for you help.

I've been following this thread with interest. My new Fat Bob doesn't arrive for another month, so I can't test these IED's myself yet, but in looking at the 08 Harley parts catolog I see that Harley offers 2 different oil caps with oil temp gauges on them (one is analog, the other is digital). Since these IED's were made by Nightrider to address the high engine temps associated with 06 and newer 96" motors I'm thinking a good check might be to invest in one of these oil caps with a temp gauge, and check the before and after oil temps with the IED's installed.

Ok, now under the "seemed like a good idea at the time" catagory, I just looked at the catalog again and it doesn't look like Harley offers a cap that fits the newer Dyna's.

OK, now last weekend I tooka 300mi round trip up the Columbia Gorge and I can say the IED's are an improvementat cruising speed, engine about 30 degres cooler ( i got a laser thermo) andmy gas mileage dropped fromm 44 to 42 mph.
Performance improves subtle but noticeable;
So I would recomend these. Bear in mind, I have the stg 1 download (opened up the rev limiter and more fuel on the high end($150.00) and now $70.00 into these IEDs, so, for $230.00 I have a fuel mgmt system that works for me, yet it is not adjustable or anything like the fuelpacks, PCIII, etc.But I'm happy with the way I run now.

Labfreak
I'm happy thatyou are satisfied.

Keep your face in the wind.......

I posted this in the Tech Forum but copied it here since it was relevant and you could see my personal results:

Things I have not noticed but doesn't mean they aren't/didn't happen:
- louder exhaust
- more performance
- temperature change....well maybe, but is it me just wishing it? Hell I don't know but I hope it is cooler.

Things I have noticed:
- low rpm surge is MUCH less if non-existent but I really went low to make it happen yet very noticeable change.
- spark plugs look much better. Not as white - can definitely see a color difference from before and I'm sure it would be better if I cleaned them more before the run.
- one thing that surprised me that I did notice and never really thought about is while moving at a low/midrange rpm in any of the gears the 'casual missing', you know, like you get sometimes when there is not really enough fuel in the mix for the spark to create an ignition which feels like a random dead spot, was also gone and made me really take notice.

So, just by these simple findings the IED's are doing something. Is it the best....no but for the cost the results are very impressive. I would say this is for those who don't want to spend money on a fuel manager and help their bike run at a healthier state be it only .5 richer in air/fuel ratio.

For the record, I have the SE Air Cleaner, a Stage 1 Download, and Rush 1.75 slip-ons.

Good report db and don't forget you are basically stock so if you have problems away from home any HD dealer should be able to trouble shoot it which may not be the case with an aftermarket fuel management system.

Yep, my plugs look lite brown,not so white, I heard it is best to checkyr plugs after you run up at speed,cut your motor and pull over so you can see how they look after running, NOT idling.
Tech Forum as some other good data on these IED's good investment for the $ IMO.:)

Anyone tried the DYN Oied's that are for the 06 year only? I'm thinking about giving them a try but can't decide.

Just put mine on. Saturday went for a ride and noticed a big difference. I have an 06 street bob with a Big Sucker and Cycle Shack Slip-Ons. I had a pop twice on decel, noticed that I was cruising at 80 mph in 5th gear very smooth, cooler engine (even though the day was burning hot) and all around better performance. My check engine light did come on for about 15 seconds or so and just switched off. All in all, I am very happy with everything. I even check my plugs and they looked great.

BRK was the check engine light a one time thing, or every time you have ridden?

If your engine light went on, then you probably have ECM codes: Here is how to check:

Turn everything off, turn your start/safety switch to ON
Hold the button on behind your speedo
while holding the button down, turn on your ignition (with key)
Your speedo needle will do a sweep, and you will go into Diag mode,
P 5 55
hold button when each one comes up and check for your error codes:
P0131/P0151 are usually the ones

(DOa search on ECM codes, for better,more complete instructions)

Check your codes.
My light came on twice on the way to work, then I cleared them.
The light came on once on the way home, front sensor lean.
I haven't gone for another test ride yet.

Mike

Sound to good , after reading all I bought it :) get not wait

thanks for all the advice. i'll be sure to check the codes.

Since I started this thread, I should explain what I have found since I first installed my IED's:

Before I installed my 2-1 pipes I had stage 1 download, cycleshack slip-ons and the K&N hiflow airfilter, I did not get any ECM codes and the bike ran better with IEDs.

I installed the PYTHON 2-1 and no other changes, I got the ECM codes P0131/P0151 indicating "lean conditions"

I took off the IEDs and the codes went away.( Obviously, the codes are due to the IEDs)

I told Steve at Nightrider about this, he sent me a new pair of IEDs: I still got codes.

Steve sent me a pair of DYN o2 IEDs: I still got codes (my bike is an 07 Dyna)

Steve sent me Xieds: I still get codes, but bike runs good with Xieds so I just leave them on and not get too worred about the ECM codes.

SO, my guess is that there is smething about the 2-1 pipes/IED combination that causes these codes to appear, but that there is nothing really wrong....I hope...my plugs look fine and the bike definitely feels like it is running better with the IEDs.

Steve told me h is looking into this.

BTW, most of the rave reviews come from baggers with stock intake and mybe they added slip-ons.

Definitely runs better at low RPM's with IED's installed and better roll-on response at cruising speeds. the results seem to be highly variable depending on your exact setup, it appears that the FLH benefits more from the XIED's while the Dyna line responds about the same with either, though if you have a full exhaust system as opposed to just slip-ons you may be better off with the XIED on the Dyna. I tried both the IED and XIED and didn't see much difference., I've got SE slip-ons and stage I intake/download. I got the most performance gain from adding the slip-ons and the regular IED's. Adding the SE intake and download did nothing aside from a bit higher idle speed and, presumably, a higher rev limit (I'll likely never hit). I'd go back to the stock intake setup except I like the little round air cleaner I've got on it now. That '08 cover is a monstrosity in my opinion.

Here is a stupid question:

I ordered my DYN o2 IEDs last weekend. Hopefully they will ship by the end of the week.

It says on the nightrider.com website that they work with the PCIII (which I have installed). I am curious as to how this can be? The PCIII has O2 eliminators. Will I hurt anything by installing the DYN o2 IEDs with the PCIII still attached?

I am thinking that it will run rich.

Am I way off base here?

If you go to this page www.nightrider.com/parts/ied_product_line.htm (http://www.nightrider.com/parts/ied_product_line.htm)it tells you not to use the O2 eliminators.

Letus know if the DYN OiED's make a difference.
