Re:O2 sensor placement does it matter?
 

Jeff,

No one has given me any insight yet on how their car is running if they have a pw0 or pr3 ecu that requires two o2's, and have just one in the downpipe reading both pairs and connected to both ecu inputs. Do you know anyone with a jap b16 not running a chipped ecu? Do they have their o2 setup like that? How does it fair?

is a 4 wire o2 sensor a wideband or narrowband ?

We did a B16a setup along time ago, it used the PR3 ecu, we put both o2 sensors right next to each other in the DP and worked fine.

Most likely narrowband. Tell me the year/make/model of the car and I could cross ref it.

Damn, tell me turbo has been doing his o2 sensor homework.

i have a 95 del sol d15 with a 4 wire o2 sensor is it narrow band or wide band ?

Re:O2 sensor placement does it matter?
 

4wire is narrowband. The only Hondas that I know of that came with wideband (5wire) was the 96-00 HX and the older model VX (valve cover says VTEC-E)
