This scale corresponds to the temperature readings from the temp sensor on the coolant return pipe right at the front of your engine. When an engine is cold it needs a little more fuel to keep the engine turning and to heat it up faster. This table properly adds fuel according to the coolant temp. The colder the coolant the more fuel is added.
I dont recommend playing with this very much as it could really affect how well your car starts up. However, if you have a larger radiator, larger oil cooler, and cooler thermostat which lower the normal operating temp of the engine, lowering the last few values will keep you ecu from adding fuel you dont need.
