Hey whats up guys. I have a couple of questions:

How many wires are our stock o2 sensors ( upstream o2 sensors)? and should I get an auto meter a/f ratio gauge.

Second: What other gauges are better for monitering the ratio other than the Greddy unit, and if I use the Greddy unit, Do I have to weld the O2 they supply or replace it with my stock upstream???

Thanks for the help.

 

Sorry I forgot to add that I have a 5th gen Prelude. Thanx.

Their only good for display...

 

We need to have a sticky on this. YOUR STOCK O2 SENSOR SUCKS AT TELLING WHAT THE A/F RATIO IS!!!! only a wide band o2 sensor can do this. your stock will read 1v if the ratio is more than 14.7:1 and will read 0v if the ratio is less than 14.7:1. Thus it will read lean or rich, nothing else. not how lean or how rich.

Prelude is a 4 wire, btw.

 

i had an autometer, but it got a little annoying

Are you sure? Is this true?

If it is, I'm getting a wide band O2 kit for sure!

 

Yes i'm sure

 

So does this wideband thing you speak of come with the autometer AF gauge?

Techedge isn't far down on my shopping list, can't wait.
