        I have a Buick GN; the MAF sensor is spec'd to go about 32Hz to
     150Hz. The signal is a square wave. As part of a data aqu. project
     using a 6811 I was reading the freq of the MAF. A peak airflow
     value of 255 gram/sec corresponded to about 140 Hz. The gram/sec
     reading was output from the ECM as part of it's diagnostic data
     stream.
