Ok I have a b16 obd0 and I put in a plm header. I had two o2 bungalow welded into primaries 3 and 4 but its still running rough.

Is there anyway to have the obd0 ecu chipped or tuned to disable one or both of the o2 sensors? I don't really know the first thing about ecu tuning so any good leads would be helpful.

Also I can't really afford to do an obd1 swap at the moment so that's not really an option. Thanks!

Disabling the 02 is a feature within the tuning program itself, assuming said program does in fact offer such. You can "disable" the 02 sensor via hardware modifications to the ECU, but it won't give you the results you seek.

Also depends on which version of which obd0 ecu you have, some are capable of being chipped and some are not.

Wow thanks. So let's say I wanted to have it tuned then. What would I need to buy before taking my car to be tuned?

Try hondata, they sell ecu's for this purpose.

You need the O2 sensor to run properly in closed-loop mode. If you disable the O2 sensor, the ECU will run in open-loop mode all the time and your efficiency will decrease dramatically. If you're not running properly, you need to fix that instead of disabling things that are necessary for proper engine operation.
