AEM wide band on civic help
Ok i bought a AEM wide band, had the car tuned already. was wondering if i took out the o2 and just ran the wideband will it mess with my tune/a.f ratio?
I just installed it on my car and my a/f is going crazy. So pretty much i am asking on my eg do i need to run the o2 sensor and then have a bung welded in and run the wide band in that. thus having pretty much 2 o2s.
Or can i have no o2 on my car and run just the wide band sensor?

Re: AEM wide band on civic help
what is the car tuned on? u can turn the factory o2 off and just run your wideband, if it is not already turned off, easy way to check unplug the factory on and see if it thows a check engine if not then your fine, if so take it back to whoever tuned it and get them to turn it off
and your kind of looking at it the wrong way, the ecu is seeing the narrow band o2, and your gauge is reading the wideband so it wont hurt eather way

Re: AEM wide band on civic help
If the ECU still works fine with no O2 sensor attached, it's in open loop mode which isn't really great for fuel economy. You're not necessarily going to run that great during partial throttle either. You can use the narrowband output of the wideband controller to interface directly to the ECU, and not use the narrowband O2 sensor. However, there really isn't much use to do that if the narrowband is doing OK on it's own.
If you need a better tune, get a better tune, and keep things the way they are. You shouldn't be running with the O2 sensor disabled either, because then the ECU doesn't have any feedback at all (which is why it's called 'open loop').
