02 sensor question

2g Monson · 07-03-2009

I just got my glowshift wideband today, and it comes with an o2 sensor. Can I just put that in place of the stock one? Will it effect the computer if I take the stock out for the wideband gauge?

Leave the stock one in there and hooked up. You don't want your wideband sensor that close to the engine anyways, it will get too hot and burn up. most people run theirs farther down in the downpipe. 12"-24" seems to be about the closest to the turbo that people put them.

Put it in your rear (cat) o2 sensor bung.

So if i put it in the rear one would it still be as accurate if I were to put it in the down pipe?

Yes, it'll be fine.

alright sweet, thanks very much

So i got another question, do i have to leave the stock one up top in? So if I put the other one somewhere i would have 3 sensors in. How does everybody else have theirs set up?

I have a AEM that I'm going to be hooking up and I read its suppose to be 18 inches from turbo

2g Monson · 07-05-2009

yeah my glowshift one says no less then 36 inches from exhaust port

You have to leave the front one in, because the ECU uses that one to determine AFR.

Yup.

The rear o2 sensor is just for emissions so you can remove that one and disable it in your ECU (if possible).
