If you want your engine to run 12.2 in closed loop with O2 feedback, you need a wideband.īenefits to Running a Wideband on the Factory ECU A standard O2 sensor doesn't know if you're running 10:1 or 13:1, so it's not useful for tuning the air fuel ratio. It can tell you if you're running rich or lean, but unfortunatley, it can't tell you how rich or lean. When connected to an air fuel ratio gauge, it can give you advance warning to let off if you run lean under heavy throttle, which could save your motor. Wideband O2 sensor vs Standard "narrow" bandĪ standard oxygen sensor (like your original oem or aftermarket replacement sensor) is accurate measuring a 14.7 stoichiometric air fuel ratio. Spending more at a store front may save you money in the end. The gauge was cheap and shipped quickly, as is typical of ebay, but don't expect any customer support if you run into a problem.
