Fuel pressure thresholds io-320

[dahugo]

I searched and found a thread with appropriate fuel pressure thresholds for a carb'd engine but not the io-320. Anyone know what's low and what's high? I would like to program my fd180 appropriately.

This is from the my Lycoming operators manual.

IO-320-B, -D, -E Series;AIO-320; LIO-320-B
Inlet to fuel injector: Min 12, Max 45

IO-320-C Series; LIO-320-C
Inlet to fuel injector: Min 14, Max 45

depends what you have. From memory the AFP FI servo is happy between 14 and 90 psi.
