i posted from the latest version from fast ccom download (5/15) and it says in title of file "set map to 4 bar"
that file looks like it was created 2/11and there was another aem3.5 cal file 9/2011 version
If you put in the values i gave you then the MAP will be accurate to 3.5bar absolute based on a .5-4.5v reference range. You can select any value you want for MAP sensor as long as the calibration table is correct for the voltage reference range and MAP values
