Xieds....
This modern electronic stuff confuses me, can someone explain in plain English about xides....
Dose it just plug into the O2 sensors harness..?
And whats the dif, between Vieds and Xieds.
I have a 2012 SG.
I have a stage 1 breather from ness.
I have decatted headers off a 2010 SG And I run a stock muffler.
Do I need to run a Xied..?
Thanks or all the help.

 

THEY are used for changing the AFR if you do not want to go fancy and get a tuner. The XEIDS are factory set around 13.8, the VEIDS are slightly adjustable. They "trick" ECM to push more fuel, advertisement says 8%. I put them on my 08 Ultra Classic, 96 engine, all stock. Runs a little cooler, and slightly better throttle response. BTW, you just plug them into the harness between the sensor and the ECM, very easy, takes 15 minutes. A lot of noise on the forums, guess depends how much you want to turn a wrench or pay a wrenchhead. For me, does the trick, but 08 have no CATS, so a simple process, no fuss. Your bike, I am not a mechanic, just a rider, LOL. Go to Nightrider.com and read info and what they recommend. As far as do you need them, that is a personal decision. I think they do as advertised, and gets the bike out of such a lean condition. Leaner = hotter.

 

The xied/vied's simply connect between your oxygen sensors and the ecm. They will lower your air fuel ratio (AFR) and your bike will run cooler. Its a worthwhile investment

 

I use the xieds on my 09 FLHTC- to very good result.
I have stock ( no cat for 09) headers, high flow intake and exhaust.

they just plug inline.

to select the correct version just choose from the nightrider.com website, Steve Mullen is great with answering questions.

how they work:

o2 sensors produce voltage as a reaction to the amount of o2 in the exhaust gasses- from this is can be determined if there should be more or less fuel added to the air entering the motor- and in 'real time'- adjustments are near instantaneous, made by the computer- which is also taking in sensor input on speed, temperature, rpms, air density and other factors

more voltage means that the motor is running rich...

less voltage means that the motor is running lean...

most systems in use the past 35 years calibrate for .5 volts to be "perfect".

the xied/vied is simply a resistor network which when in line with the o2 sensors, makes the computer think that the mixture is leaner than it should be ( because the resistors reduce the voltage going from the sensor to the computer).
so the computer makes the mixture slightly richer...with the xieds about 8% richer.


this is in effect when the motor is fully warmed, throttle position is part open ( not wide open) and when cruising- so under most riding conditions.

MPG will be slightly affected- mine dropped from 44 to 43 mpg ( measured over thousands of miles, before and after)

these are a good solution for a stage 1 motor, further mods require a more complex approach.

in my case, my stock bike had a ping problem at 2800~3200 rpms running up 6% grades. xieds solved that and I later added high flow in and out, to good effect.

They do what they claim. I'm running a set now of VIED's (adjustable), but they will be coming off next week when I get my Power Vision.

 

Some great explainations on how they work. Have them on my 2012FLHTK, (XIED'S) and am very happy with the result. A little cooler and improved throttle response.Do you need them if your bike is running OK? Maybe not, but in my opinion they are a cheap investment in improvement in heat control and throttle response quality.

 

if you are not doing cams or anything else they are great. get the vieds as you can fine adjust for any air cleaner or pipe change that may create popping in the exhaust. i run mine at 50% and it runs good.

 

ive got xeids on my 07 sg, put them on bout 4 mo ago, im running stage 1, s.e. a/c, fullsac true dual kit, s.e. mufflers with fullsac cvo cores, they plug inline the bike runs a lot cooler, even with the free breathing I had on already, throttle response is better also, did 200 mi this weekend and seem to get more mileage out of the tank too, but don't keep track of it well worth a hundred bucks. bud

 

can u run xied,s in a 2013 ultra or do u have to have some other newer model. i pulled them off my dyna and was wondering if they'd fit my 13 ultra

 

The ones off your Dyna won't work on your Ultra. You need the FL-Xied-10 versions for the newer touring models.
