strange o2 readings I`m having a problem getting my o2s to read the same, @ WOT b1 reads 980mv and b2 reads 900mv I just noticed this problem a few days ago. my ltrims are locked in at about -4 under WOT for both b1 and b2. but my injector puls width is shorter on b2 then b1 by a few hundreths. but the car still seems to run normal,lots of boost and low rwhp 
. anyone have any idea whats causing this? thanks in advance.

Re: strange o2 readings it may be because of the configuration of the turbo kit.. you know the b2 reads only the passenger side and b1 reads both sides.
easy try is look at the plugs
i thought your rwhp had improved?

Re: strange o2 readings Hey dave, it is running alot stronger then before but still ain`t putin down what it should IMO.and i`m still tryin to get my fuel where it should be it`s all over the place @ WOT now. so since b1 sensor is reading off both banks do you think that i`d be safe to tune off just that one sensor? also alittle off topic but, filled up with 1/2 110octain 1/2 93octain last night and still getting occasional kr so i`m pretty sure it`s false now.Thanks.
Re: strange o2 readings good to hear its false.. now if you can get ahold of the new edit 1.3 then you can tune out the false knock 
when i look at my 02's i rely more on the B2 sensor than b1 actually because it hasnt been through the turbo.. the temperature and pressures on that one are actually what the cylinder is producing vs. the one after the turbo and its oil and the exhaust temperature drop etc.. thats the way i look at it

Re: strange o2 readings i had a similar problem, now i dont have as much done as u but it had to do with my plugs and wires not firing good causing a richer reading by about 600-800 mv too high...maybe a possibility?
