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 the Enrichment 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.

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 enricherners for about 6 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.

Mdog2222!!!! IS BACK! Hey man, what up!! Yeah, thinking these might be worth a try..I'm still saving change for those Sideshots, but keep getting interesting feed back on the 2-inta-1's.
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??

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 mixture if you let in more air due to "better" air filter.
But you are in the OK area wthout the download with only mild 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 quite up to the same temp compared to a normal day in texas so this needs to be in the calculation on my answers..
On JEFX q: just differ on who makes 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 on my Harley but on my fun bike have a Direct link (Buell XBs).

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 really cared.
I hardly use the cruse mode on my Buell, it's a race bike so the steady run style isn't my bag LOL....

yes, not many bikers can feel +- 5hp/10ft-ib. So the not so nice hole in the wall type tuners 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 the pants 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" are a bit fuzzy and normally promise more than they can deliver out of the box).

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
OK, Trotter and Kricke, you motorheads!!! So, 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).
