were did you put your wibeband o2?

[DSMer541]

( 1g ) im going to run my stock o2 and put my wibeband sensor in the down pipe....but i was wondering were a good place to weld it into at? before the bend closer to the o2 housing or after the bend in the down pipe? should i get a regular bung or a 45 deg bung? just curious how other people with a 1g put there wideband sensor in.

I have my bung mounted in front of my cat. 2G btw.

You want to put it ~36" from the turbo/manifold before the flex pipe/cat if you still have it. Here is a good visualization but I put mine to the side and not vertical as shown. Hope this helps.

all depends on what the manufacture of your WB tells you about how far back to put the sensor. i just put mine in my Subaru about 18" from the back of the turbo, but on the dsm the best place is defiantly somewhere between the bend and flex pipe.

Good posts here, good advice, the 36" rule would be fine.

Before the cat somewhere around the bend or upside of the downpipe would be fine, you don't have to go out there and measure it perfect. I've run multiple ones in multiple places with good results...including past the test pipe, way beyond 36". But the upside or downside of the bend before the flex section would work just fine.

AEM's works fine mounted about 6 inches below the flange from your O2 Housing/Downpipe.

Just keep in mind that an exhaust leak will affect your readings.

The further away it is, the slower the response is. Put it either in the o2 housing or close to it on the downpipe. It's pretty much proven that even in the stock location, a wideband will last for a long time. Tons of people on EvolutionM have theirs in the stock location and have never seen an issue after years of use, both driving every day and racing.

well if i put it in the stock o2 housing location ,then were do i put the stock o2?....... thanx for all the good info guys

Weld a bung on your downpipe as it turns parallel with your car underbody. Make sure that the bung is at an angle towards the pipe, so that the sensor doesn't act like a plug below. You don't want it accumulating moisture. Leave your stock o2 sensor in place, otherwise your car will run crappy.

I went " 18 down from the O2 housing... Works great.

by "at an angle" do you mean use a 45* bung?

 

[jrohner]

Just at an upward angle instead of downward.

 

[mike96]

here is a good example of what he means "at an angle"

[knochgoon24]

You want the o2 sensor above 9-3 o'clock position. If it's angled so it's in a 3-6 o'clock position, condensation can form on the sensor. Not good.

 

[DSMer541]

oh okay that makes sense....thanx guys!

Sorry to bring back such an old post but I have a question. Basically I bought a thermal research 3in exhaust with an apexi downpipe and I was wondering if I can replace the stock o2 sensor with my wideband o2 sensor? The bung is probably 4ft or a little less away from the turbo/manifold.

 

[proteusx301]

The o2 sensor that you are talking about is your catalyst monitor. You are probably going to throw a light if that is removed.

 

[1gentalonfan]

IF your talking about the stock bung in the o2 housing that's more like a foot from the head, but depending on the wb and the tuning system your using you can just replace the stock. Assuming your still on a stock ecu, if you have an LC-1 or LM-1 kit they come standard with 2 outputs, a regular wb output for the gauge, and a simulated narrowband output that you can wire right to your ecu where the old narrowband fed to. Pin#4 on the big harness i believe. you can also then program each output to whatever you want. I have mine wired this way and both set to wb output as im running jackal and its set up for a native wb. Having it in the stock location isnt going to affect its life really, but it will give you a more accurate reading. Just make sure you let the wb fully warm up each time before starting your car, this is an absolute must as the exhaust will stick to a cold sensor and ruin it VERY fast. There should be an led that will blink when warming up and then stay solid when its warm. Or my gauge blinks full rich until its warm.

 

[giovanniv]

No I am talking about the rear o2 sensor. But if my car just throws a cel then I am fine with that as I can deal with it. I just don't want my car to run like shit as a result of not having the stock o2 sensor in.

 

[jeffo]

The rear O2 is really only there to test if the CAT is working. It won't make the car run bad to remove it, but it will throw an MIL.
I have heard of guys though that leave it still plugged in, and just wrap it up well in tin foil, and it won't throw an MIL. You can try it.

 

[twdorris]

It's pretty much proven that even in the stock location, a wideband will last for a long time.

I'll second that opinion. I've had my WB in the front O2 for a long time now with plenty of 20-30 minute sessions at the road course over a few years. No issues.

In the downpipe before the flex section..

 

[standard235]

My Innovate LC1 is in the stock location and I'm using the analog output to simulate a narrow band!

 

[giovanniv]

I was also told by a friend that if I am putting the wideband o2 where the stock rear o2 is at that I should wire the red wire and white wire to the factory wires that were on the stock o2 sensor so the ecu reads the new wideband o2 sensor. Is that correct? It would look something like this. Sorry about the terrible pic but you get the idea....


Sorry and those red and white wires are coming from an innovate lc-1

For you guys running it in the stock location, how long does it take the wideband to warm up before you start the car? Is it a few seconds? or a few minutes?

 

[KT_McHan]

im curious about this also...i just picked up a lc1 and if i can it as wideband and stock o2 to ecu that would be great.
has anyone tried this?
