Curious if anyone had a transfer function for one of these sensors.Specifically the ones in late 80's Porsche 951, or even one similar.I can get the exact part number if needed.This will be of great help to me and I will be extremely appreciative if some one could post/send me it.Thanks in advance.

Bosch vane airflow sensors

I doubt very much if that information is readily available, but you could always measure it yourself on an airflow bench.
An even better way may be to place the Bosch in series with whatever you plan to replace it with on a flow bench, and compare the two output voltages directly over a wide range of airflows. The electronic "black box" interface for the replacement flowmeter can then be tuned fairly close before it even goes on the car.
I did that when I replaced my old flapper with a more compact hot wire flowmeter, not on a Porsche though.
