Thanks guys, I took the data there and wrote a little bash script that takes boost input(psig) and spits out kPa and the voltage the ford 3bar map would read.
I called the file
3barmap.sh, this can probably be replicated in a spreadsheet function or whatever. I might add additional functionality like converting from kPa or showing what boost numbers are at a specific voltage.
How do you know what voltage you have alkycontrol PAC set to with the potentiometers? It seems like .1v corresponds to about 1psig of boost, that's pretty precise IMO. I feel like this can make the setting for each person vary greatly depending on how long their wire run is and the resistance associated with it, causing voltage drop. Hell, AWG of the wire, quality of the splice, and even heat can play into that.

if [ -z "$1" ];
then read -p "Enter boost PSIG start target:" boost;
else boost=$1;
fi;
kPa=$(echo \($boost+14.69595\)\*\(6.8947625\) | bc)
Vout=$(echo 0.0146428\*$kPa+0.1072 | bc)
echo Boost: $boost psig
echo kPa: $kPa
echo Vout: $Vout Volts
