o2 sensor gone???

[ashero2]

aite guys ive searched for a while now and cant really find too much info.
running a sr20 with a 20g turbo according to what the guy told me. definitely not the t25 turbo I can say that at least. looking over the car today and noticed that the guy had the o2 sensor out and the bunge was capped off. the car has been running fine and haven't noticed too many problems with it. wondering if I should get a o2 sensor and put it in or just run without one. is it safe to run without one.
talked to one of my boys and he says the car will just run off the pretuned map for fuel mixtures.
going to be taking my down pipe off today and slap in my wideband soon so I can read my afr and hope im not running lean. please help

The wideband must be placed 3-5 feet away from the turbo. You will need to drop the downpipe and have a bung welded into it, at a proper angle, please read the wideband instructions for more info.

The engine will run fine without the Narrowband, what computer is running the car? I disabled my narrowband years ago because I tuned the car better without it, my running a/f ratio for cruise is around 14.8-15.1 for instance, which nets me 3-5% better fuel economy and cleaner plugs than using the narrowband would.

well I know how to install my wideband. just saying Ill be able to read my afr once I have it in.

ok then. im just running the stock ecu. 62 to be exact. haven't bought a standalone yet. looking into grabbing an apexi powerfc again but well see. not really planning on doing much yet so im just holding off on it right now. mainly get the whole motor straighten out from the kid.
