Message only source of oxygen, the oxygen is measured by OEM setup. Later downstream this air can be cooled or heated, changing the density all you want, but the mass stays the same, and has been measured. This is used to get the correct ratio of fuel to oxygen. I'm not sure that the added mass of the Methanol vapor will be accounted for correctly, since the mass you are trying to measure is really a measurement of oxygen. The mass of Methanol is usually accounted for by pressure and duration of spray.
