Eighties vintage KE systems do not have a conventional electric MAF, or a device so named.

My KE schematic shows electical leads between the "altitude correction indicator", the "air flow sensor position indicator", the ECU connector, and the fuel pump relay.

It appears the air flow sensor position indicator provides and electric analog for the position of the air flow plate, so it could roughly be described as a MAF, but is not called that by Mercedes or Bosch.

I have some KE documentation that says the signal from the air flow sensor position indicator only is used for transients when the engine is cold prior to going into open loop operation, however, others have refuted this and anecdotal evidence indicates that it is involved in normal closed loop operation.
