GM CalPak Question

[CSH-HQ]

As I recall the 148 netres is soldered in, but I hopefully have a frquency 
generator coming for MAF input, and might be able to map something out, 
comparing a stock to 55lb/hr calibration.  Comparing Pulse widths..
  Well, I got the bench sired for a 747 which has a plug in netres, which 
might lend some clues.
  Just one of a couple thousans things to do...
I'm also curious about listing out the netres/knock board numbers from the 
memcals, and seeing where that leads.
