Good News: It's in and it reads. Speed works well, needs a little calibration, but fairly close.
Bad news: I'm thinking that the quantity adjust line must just modify some map in the pump; the
mpguino readout hovers around 1/2 GPH regardless load; but does drop to 0 when there is no load. . . .
Maybe I'm missing something . . . . Setup? I just used defaults across the board.
Put in a call to my buddy with the O-Scope so I can probe the Quantity adjust line and see what we get some time next weekend.
