do you mean a wideband?

Rx-7Blazin

not sure what i mean i just heard there may be O2 sensors that provide better preformance than OEM parts

well unless you ae going to tune with a fuel computer you don't need it just get a stock unit.

yea i may get a s-afc but i just heard they let more air through

Some 02 sensors are advertised to the effect that you will get more performance. Bosch in particular. I fail to see how this could happen. Your ECU doesn't use the O2 sensor when you stomp on the gas. I suppose if an O2 sensor was more accurate, an arguement might be made for higher performance @ cruising speeds, when you apply very modest throttle. I imagine this could only be viewed with test equipment. (oscilloscope,etc) I'm no expert, but it seems pretty cut and dry.

An S-AFC is a piggyback fuel computer. It will let you program your fuel curve. make sure you know what you're doing , you can pop your engine very easily. And Ive never heard of a "performance" O2 sensor. Only widebands, which are used as a tuning tool.

Maybe a higher quaility one will give you better gasmilage. But no oxygen sensor will give you HP.

Just spend the 20 bones for the single wire deal.

ight i was just wondering thanks

exactly I ran my car for 2 weeks without an O2 sensor and it ran as fast as ever, got shitty MPG though

I replaced mine, no difference, well, except better MPG.

Some interesting sites for expanding your oxygen sensor knowledge.

I've heard a couple people claim they get very accurate results from 4-wire "performance" sensors, but those guys both had standalone ECUs and a way to datalog. Some are sold as a unit, gauge/sensor and claim extremely accurate results but I really don't believe it.

When I eventually get a WB I hope Tech Edge has their new version avail. that will accept the bosch sensor. T.E. sounds like the best bang for the buck. Just hope I can find a sensor when I go looking. I've heard recently about an intentional supply shortage for the L1H1, but haven't inquired about the bosch.

Don't trust your engine with anything less than 5 wires is the way I see it.
