The actual reason MB went to electronic fuel systems was the US epa requirement that a misfiring cyclinder have its fuel shut off, thus requiring sequential fuel injection. (at least that is what we were trained by Bosch in 1992 with the introduction of LH)

Short of documentation I will stand by the standard definition of air flow meter versus air mass meter. I see no difference between the concept of electronic airflow meters versus electronic air mass meters which was to handle density issues and the airflow meters used in KE. If they were airmass then they would be called airmass.

Originally the two electronic systems were called speed/density or airflow: D versus L for the german druck versus luft.

When Porsche sold their Carrera motor to Mooney Aircraft for use in airplanes they got rid of the motronic fuel system for the more simple reliable K-jet. K-jet may be hard to produce but it sure ain't complicated.
