The colder air stream and the higher concentration of oxygen might have fooled the ECU to enrich the mixture instead of leaning it. Maybe if you got it injected after the MAP and temperature sensors, it could have increased the fuel economy in a similar level to what you hve experienced with the carburettor-fed Mitsubishi van.
