I found out it's actually a FloScan 201, and the Skyview Installation document specifically talks about this model, including the initial pulses/gallon settings,(28,000 to 31,000), you should start up with.
Once you get it operating, very carefully log at each fillup how many gallons the system THINKS you need to fill to full, and how many you actually pump. After about a hundred gallons or so, do the math for the percentage increase/decrease and dial it in. A couple iterations of that and you'll find that the fuel totalizer is now more accurate than your fuel gauges.
