Yep, you got it. There is something about doing this on
either incoming or the gm-ecm site. Check the gm site first.
Basically plug in a 2-bar map. Change the map adc routine to
create the 1-bar map variable.

This variable gets used everywhere. That way the baro,
vac and host of other routines don't need to be changed.

Then use the 2-bar variable for the boost tables. Can
do stuff such as add in a > 100Kpa ve tbl, a SA retard
tbl. All kinds of things.
