I was referring to a Bosch mechanical fuel distributor which has a mechanical air flow meter. Tis a round disk inside the air cleaner which goes up/down as less/more air is drawn into the engine.

That mechanical air flow meter on some cars has an electric "air flow meter potentiometer" which gives an input to the CIS-E engine computer - adds more gas upon acceleration.

Here is a bit on that...
