Where do install the bung for my wideband oxygen sensor?
1. Does it matter if I install the o-sensor after the catalytic convertor? What is the difference?
2. If I install it before the catalytic, is it Ok to install it in the catalytic in the plenum? [Imagine a stock cat; with the large plenum area and the o-sensor installed there and not in the exhaust pipe.
3. If the o-sensor is in the plenum, it is not directly in the exhaust flow. What difference, if any, does this make?

It needs to be in the exhaust upstream of the Cat(s). If you don't have catalytic converters it doesn't matter. Here's why https://ls1tech.com/forums/showpost....80&postcount=3 .

i have mine after the cat after reading some stuff on the aussie ls1 forum...according to some tests done there at wot the cat cant keep up with the fuel especially the further from 14.7:1 it gets...then again i have a blower and have my a/f at 11.5:1 so you may want to put it in front of the cats just to be sure.
