Thinking about getting a wideband O2 sensor so the guys that tune my car (and myself eventually once I get HP Tuners) can tune more effectively. But from what I know, widebands fluctuate from 0 to 5 volts, while narrowbands fluctuate from 0 to 1 volts. So wouldnt the PCM not be able to read a wideband without tuning it or something? Also, would I need to get two widebands for both ports or would just one do the trick. Thanks.

Re: Wideband O2
You can add an O2 bung and run the wide band indepently of the cars O2's. One wide band does just fine.sigpic

Re: Wideband O2
Yeah when you get a wideband if you've eliminated the EGR you can use those wires to read the volts on HPtuners. Or the AC comp line. Haven't done it yet but I will here decently soon. I've got a thread from some other forum alllllllll about it if you need any help.

Re: Wideband O2
yea you don't replace your narrowbands with a wideband. It is totally seperate from them. Weld a bung in just in front of the cat.Comment
