[MBZ] Vacuum cruise controls

2006-03-25 Thread Jim Cathey
I have learned that the set speed, held as charge on the FET's input capacitor, is stored as a Idelta/I from approximately 60 MPH. That is, Vcc/2 is the initial output voltage of the error amplifier, and this is approximately the voltage out of the tachometer circuit at 60. So if you have a
