N75 1 - 670B6 & 770B6 - used in normal ECO mode

N75 2 - 67300 & 77300 - used in sport mode

N75 3 - 67488 & 77488 - used in situation with boost sensor error

Multiple SOI maps are used due to different engine, air and fuel temperatures. The ECU calculates the correct SOI map depending on those parameters.
