[coolflames]

Can someone please explain how can I get the air-fuel ratio( even though in rough numbers) from the O2 sensor voltage? :huh2:

there really is no accurate way...somebody's o2 might read 900 and be at 13.0 on the street whereas somebody elses might be at 860 and be at the same a/f on the street so there is no surefast way of going by the stock o2's...otherwise people wouldnt need to buy widebands
