I'll try to make this as concise as I can: last summer I put a DC 4-2-1 one piece header on my B16A CRX and I've been running off one O2 ever since. As a newbie to Honda tuning, I didn't realize my PW0 ECU needed both O2 sensors. So, for several months I've had one O2 sensor in the bung on the collector and I have the other O2 wire just wrapped with electrical tape.


Others here suggested I get two O2 bungs welded on the primaries, but here's the problem with that- that B16 is so crammed in there that there's barely enough room for the header--it was no easy task to install it, so I don't have the patience to go through that again. I took my CRX to the muffler shop and the guy told me that to remove the header and weld the two bungs, it would be upwards of $200 Geez...many here have had their O2 bungs welded for as little as $10-20!!


I really have to do something about this ASAP because my tags expired and I have to pass emissions in order to renew it. Plus, my gas mileage is really suffering right now.


Please vote for the best option and tell me why.

Thanks for the help!!

just do it, either way you're gonna have to weld the o2 in to pass deq. 200 dollars? what is he smoking. you can bring it to a machine shop/welder, max 20 bucks

Mount the 2nd O2 behind the Cat.

 

Isn't that for OBDII only? My B16 is a non-OBD first gen.
