How do I convert KPA MAP reading from the MAP sensor to KPA vacuum so
I can tweek the IFR table.
50 KPA map to 80 KPA = what KPA vacuum?

Just take the difference from 101.4kPa, which is 1 atmosphere pressure. So, 50-80kPa MAP would be 51.4-21.4kPa vacuum.
Your BARO value is the local zero-vacuum number,
for those who live at higher elevations.
BARO-MAP=vacuum. At boost this can be a
negative value. If the MAP sensor pegs out
then you may not index correctly across the
fuel table (or run out of IFR table), among other
things.
