All I can offer is the specs on a GN/Ttype and they are 27-147Hz 4.6-4.6v
50% duty cycle.  Those are nembers I've gathered but not actually tested.
The calibration will change depending on sensor.

 I went out to the junk yard today and found a MAF out of a late 80's
 buick, part number 25007770.  Does anyone have any info on this
 sensor or where I can look up GM sensors?  I was able to hook it up
 and get the frequency output working, but I would like to know how to
 translate the frequency to a mass flow rate.  Will this MAF be able
 to handle a 220HP 3.4 liter engine or do I need something bigger.
 Thanks
