For anyone who is an idiot like me and always has trouble trying to add to the baseline boost tables in your head, I made a new scaling to use for just these 2 tables (alt table too).
Code:
<scaling name="psia8Adj" units="psia" toexpr="(x/(5.18*2))+7.4" frexpr="(x-7.4)*(2*5.18)" format="%.1f" min="0" max="32" inc="0.1" storagetype="uint8" endian="big"/>
Just replace the 7.4 in both calcs with whatever amount your boost adder is set to over nuetral pressure for your elevation. Since I'm at 14.3psi (a lowly ~630 ft above sea level) I used 21.7 for boost adder which should generally give me resolution up to 32psi.
Now I won't look like an idiot anymore when I forget to add things.
The only silly side effect is that your mininum boost will now be off... so instead of 0 you will have whatever your difference is (for me, 7.4). I noticed this number is not common only to the scaling I created, but also for WBAFR. Does anyone know how to get around this even though the min values are 0 for each? It seems that WBAFR can also go way above the max value set for it (32 also). Is this just a coincidence of the max range of the number related to the max value here?
