so, then, that becomes another question I can tack on the originals (which I'd still like to hear more about): is replacing the o2 sensor a good idea?
Another purpose to the pc, in my mind, would be to clean up the fi below 3500, which is pretty rough!
I use to run a half system with the PCIII
, and could not get it to run clean below 3k. After I Put on a full exhaust, installed a map from dynojet and bada-bing, bada-boom, no more glitches below 3k.
The sensor would be fighting with the PCIII
, I suspect - with it leaning the mixture, then the PCIII
taking that signal and richening it (according to the fuel map loaded), so the O2 sensor may not have full effect, and the PCIII
may not have full effect (in those situations) either.
An O2 sensor, the way Honda has it setup for OE running, only serves to placate the EPA, gas mileage is a pleasant side effect.
I can't say that repllacing it is a good or bad idea yet, I haven't been able to do it. I don't thing there would be any harm in doing so, but you may ecperience driveability issues. Then again, you may just get good gas mileage again...............
