In post #1 there's a new link to version 1.1a of S300Calculator.
Previous versions of SManager had a bug that caused the display of incorrect MAP values when the scale was in PSI. I had to introduce the same bug in S300Calculator so the MAP values in PSI will match SManager when presented in S300Calculator.
I noticed the current version of SManager has this fixed, so I could remove the bug from S300Calculator as well, and that's version 1.1a.
