Just as a side note to save any confusion, remember it's not mg/rev - rather mg/stroke.
mg/rev does work on a 4cylinder engine (4stroke, 4 cylinder per revolution of the crank there would be one induction stroke) - however this doesn't calculate out for a 5 or 6 cylinder. The ECU knows how many cylinders the engine has, the current mass flow rate and the engine speed - therefore it can derive how much air is being delivered per stroke.
