I'm assuming "MAP" is Manifold Absolute Pressure.
Although, in this case, "map" is simply a plotting of points on a graph, connected with lines, and various plots are superimposed onto one graph, leaving a bordered, shaded in region which are the operating parameters and values. When one goes one by one, you might have a plot for 91 octane, with the respective ignition, fuel, knock, and a host of other values. That's one kind of map. Then there could be ones for 87, and ones for 85 and bad gas.
