Wideband o2 vs narrowband o2 Options

[doory100]

I am debating on whether to get a wideband o2 sensor or a narrowband o2 sensor I have a mild performance build with cams and an AFC neyo - also intake manifold and exhaust manifold. Shaved head and port and polish. I found a aem aeugo meter and I am wondering if a factory wideband o2 sensor will wire up to the meter?

You don't have a wideband sensor from the factory. You have a narrow band sensor as stock which generates a 0-1V output a signal that just shows rich or lean on either side of stoic but not really how rich or how lean with high accuracy. A wideband is fast, accurate, and reliable and actually outputs a 0-5V signal that tells how rich or how lean the exhaust actually is. That whole 0-1 volt range on the narrow band is the wide band bouncing from 14.5 to 15.2 or something (working from memory here). Here's a nice article that explains it more.

Sorry I'm aware of the difference between a wide band and a & a narrow band o2 sensor. I was wondering if I went to a scrap yard and got a wideband o2 sensor off say another car that has a wideband o2 factory sensor. I'm wondering if that would hook up to the Aem meter or not?

Likely yes, but they do age and loose accuracy and may not use the same connector which would mean you'd have to hack and splice. I don't remember my connector shape but I just changed one in a SRX and it was rectangle with a little ear sticking off.
