I cannot search with the words "o2, second", and I couldn't find it with the search terms "oxygen sensor".

My stock Honda CRX 1.6 VTEC (standard model in Europe) has 2 oxygen sensors. My downpipe has 1 o2 bung in it. My Rev Hard manifold has no o2 bung(s).

- What have you people done to run the B16 with a turbo?
- Do you have two o2 bungs in your turbo manifold? (1 for each cilinder pair)
- Did you convert the two o2 senors to one? How?
- Do I have to replace my ODB0 with a ODB1?

I have a OBD0 b16a so i welded in two bungs, but decided to use http://www.turboedit.org and a pm6 (si ecu) with a vfac for vtec control, THe pm6 uses only one o2 and im using the other for wideband.

Where did u weld in the two o2 bungs? One in each runner pair of the manifold?

About Turboedit: What do you have to do with the ECU? I cannot find info about that on their site. Nor could I find it in the forum of http://www.pgmfi.org/.

Or can you just follow the steps of Uberdata?

you will want to put the bungs in the downpipe not in the mani,has to be after the turbo.

If I put the two bungs after the turbo they won't be able to read the right A/F ratio per cilinder pair. I think the ECU won't be able to correct the A/F ratio for the right cilnder pair. It will probably run as bad as when I exchange the two wires of the two oxygen sensor with eacht other, right?

Does anyone has the two oxygen sensors in the downpipe? And do you get a CEL?

it will be able to read it. look harder in pgmfi.org cause there is aforum, dude research the pm6 set up for b16a boost,

JOeS

I couldn't find the correct forum right away on pgmfi.org Sorry for that! But now I have and there's tons of info

But, I just need a quick answer.

If I replace my PW0 with a PM6, can I use just one of the two PW0 oxygen sensors? Is so, which one do I have to use?

Or is it better to get a PM6 oxygen sensor?

Either O2 sensor will work. The only difference is in the connectors. Matter of fact you use a stock CRX O2 sensor to replace your blown b16 one when the time comes, it's a perfect fit so there's no point in swapping.

the two o2s are the same, all obd0 o2s are the same
