I think the oxygen sensor regulates the ratio of air:fuel. The ratio that is re-occurring in my reading is typically 14.7:1. If this is correct then I'm confused as to the benefit of a CAI? Would't the ECU compensate for the change in air volume/density resulting from temperature variance and alter the amount of fuel introduced to maintian 14.7:1? Can the terms volume and density be interchanged in this discussion?
Thanks.
Thanks.
