quick question, does the 02 after the cat in any way affect engine performance. I was talking to the guy at the exhaust shop about putting one in and he said that its fine if i just do it for emissions but not good if i leave it in because it works in conjunction with the o2s by the manifolds and tells the engine if its running too lean or rich?? is he right i thought it didnt affect it

Re: 02 sim
thats what i thought but he says if i put the sim its going to be sending a wrong reading to the engine saying its fine when its actually running too lean or too rich but isnt that what the o2s by the manifolds are for?Comment

Re: 02 sim
The sim reads nothing but perfect codes. It tells the PCM that the rear o2 is reading exactly what the front o2's are putting into it.Comment

Re: 02 sim
The post cat O2 sensor simply tells the pcm if the cat is functioning properly.

Re: 02 sim
Instead of buying an O2 sim, you could get a spark plug non-fouler instead: http://www.s2ki.com/s2000/topic/2299...st__p__4367609Comment

Re: 02 sim
I see. Then put your year in... o2's are all the same. If they're 4 prong they'll fit.Comment
