OBD2 Honda ECUs can't be chipped, which is why OBD2-OBD1 conversions are just about the only way to go.. The emissions thing is area dependant, if you live somewhere that hooks up to the OBD2 port and looks for stored codes, etc., you'll fail. If they just check emissions with a sniffer, you can do fine if you're tuned properly. If you have a turbo setup, use the OBD2 ECU for emissions and stay off boost until you get your turbo-tuned ECU back in.
