VCM scanner has AC pressure (V) while VCM Editor has FAN Desired % vs AC pressure (psi)

Is there a voltage - pressure chart available somewhere for a TBSS sensor, or maybe a way to have VCM scanner display PSI instead of volts? This way I can tell where the AC pressure is related to actual and commanded fan %'s.

I am trying to tweek the fan settings for better AC performance in extreme weather 110+ degrees. (biasing off engine temperature causes a delay with warmer inside ac temps while the engine warms up due to lack of enough fan.)
