i have an off-road y pipe, and am not going to use the rear o2 sensors. having them tuned out. can i just use one of the 2 bungs set up for the rear o2's? or does it have to be behind the y? i was just wondering because that would mean the true duels guys would need 2 wideband sensors? i have a wet shot and its an 02 A4. thanks.

Yeah, you can use one of the rear O2 bungs.

alright. i would think u could take the readings out of one side.

Use one of the rear o2 bungs already there after he shuts the codes off.

Why would an off road Y have rear O2 bungs?

well when i talked to him, i had stock cats. so maybe he was thinking i was keeping the rear o2's? i don't know y either but thats how it came. i bought it off a friend so don't know the brand.

many do, so you can keep the stock sensors installed. (and run similators)

my offroad Y has rear bungs, and I use them for my wideband all the time.

I see, I had the joy of welding one in mine. It really wasn't that bad I got the thick stainless bung.

One question still. Would it be better to put it in after the Y joins so you get an average of each bank?
I had a wideband with one sensor, I have seen some newer ones that use two.
Seems more accurate to put one in each bank and use a wideband with two sensors.

put one in both banks, then you can swap banks to identify a problem if one exists.

We weld one in all the cars we tune. Put it facing out. It makes it alot faster to put in and take out. We just use one side. I watch the narow bands and make sure all looks good.
