Vesc tachometerAbs/rpm

[Supman45]

I have noticed my tachometerABS seems to stay between 0-1024 respectively. with delays put into the system even after the device has been turned off, is there a way so I can zero the data to get a more accurate reading at higher speeds. I also noticed my rpm values for my motor seem to be astronomically high when I set it to 1(using setRPM()) it is saying it is going roughly 1000 rpm.
