On mine LOD is Engine Load - Percentage of full power being used.
MAP is Manifold Absolute Pressure - PSIA (pounds/square inch absolute). Since static air pressure (sea level) is 14.7psi, numbers above that are boost, and numbers below that are vacuum. I use MAP to monitor boost.
If your Autometer boost gauge reads 0 at no boost, then it is reading PSIG (pounds/square inch gauge) and the numbers will be off by about 15psi.
