Default Intake air temperature compensation?

Hey guys,

As most of you know, without MAT input the car would run lean during cold weather and rich during hot weather, so the MS3 has a MAT fuel correction curve based on the ideal gas law. Nothing in reality ever matches ideal gas law conditions My car was acting the opposite of a car with no temperature correction, rich when driving in cool weather and lean when driving in hot weather.

Has anyone made a curve that works well with real world conditions? I am fiddling with mine day by day but if somebody has already perfected it please post up!

Because the air is cooler than the heat-soaked sensor; so sensor go hey its hot run less fuel while there is actually more air available hence lean. MAT correction issue - leaning out on hot starts

[edit] upon rereading your post I'm not sure this applies and I don't have another answer for you.
