Table values injections and advance Moto Guzzi Norge 1200

[turbina]

Hi,
sorry for the questions, but I am a beginner...

After having suffered to read the file of my Guzzi, finally, the load on the ECM.
I kindly ask you for clarification in order to understand the meaning of some tables which I enclose.

1) The values of the map fuel injection shown in the table what do they mean? What unit of measurement are they?

2) on payments On account, in addition to the base map, there are "Advance correction f(ETC)" and "Advance correction f(T_AIR)".
The first "ETC" refers to the correction based on the engine temperature?
The second "T_AIR" I think it can refer to the temperature environment, but if so why is it all zero? Not serves to correct the advance to the change of the environmental temperature?

3) The map "Step Injection" what is it? and those values what do they mean?

4) The detailed limiter means 4 values. The question is why the four data, however, does not coincide with the reality, as my bike is a plant of 8000 g/m?

I ask again sorry for all these questions....
