Ok I have the plxm300 and hondata s200b. The plx is feeding the ecu a narrowband signal. I read somewhere that you need to tell hondata to "disable primary o2 heater" but i never did that - maybe my tuner did, idk.

Anyway im running open loop, so technically the ecu doesnt even need an 02 signal right? I keep getting a damn "code 0" which i know is a glitch with hondata but im wondering what would happen if i just completely remove any type of o2 signal from the ecu?

Will it go into limp mode? Will it throw a CEL for no o2 at all? Im tired of it randomly throwin code0 so i want to eliminate that without removing the CEL bulb lol. I dont notice a performance difference when it throws a CEL- its just annoying!

Suggestions? Why does this even happen? Stock reads 0-1v plx narrow o2 read 0-1v i dont see the issue.

If you are running open loop, meaning the O2 sensor is disabled and the o2 heater is disabled. Then it doesn't need a wire going to it at all really. This happens on some cars and doesn't on others. Its kinda odd. My EK hatch doesn't throw code 0 in open loop, but my sister's eg hatch does.
