would the 02 sensors still be a good means of monitoring the engine under racing with the nitrous? Or would the nitrous combustions throw the 02s outta wack and be useless? I wanna watch the 02s as I make a nitrous pass to make sure im in the rich side of the A/F ratio.

.890 is ideal correct?

 

You'd probably have better luck with an EGT gauge.

 

go dyno your car with the nitrous and check the air fuel there

 

Take a look at this thread: http://web.camaross.com/forums/showt...hreadid=207675

that thread gave me brain damage

 

Well, let me simplify my answer: O2 sensors MAY not accurately reflect the AF ratio when running N2O but can still be used as a tuining tool.

Rich Krause

 

if im not mistaken,the stock O2's are ignored at WOT due to them being a narrow band sensor. i have an A/F guage and at WOT it reads dead rich,even when we leaned out the car on purpose to see how accurate it was.

IMO it's a decent tool,but i wouldnt count on it.

 

We (or at least I) am talking about wideband sensors used for tuning.

Rich Krause

 

Rich,im sorry if i implied you were talking about stock o2's,didnt mean for the confusion.

wideband is definately the best option.
