evos using the factory air temp compensation will run leaner as the temperature drops. tweaking the air temp comp table can give stable afr vs air temp, but i've not heard of anyone trying it yet.

That would deff explain why I came out running a bit leaner in cooler weather. It's hard in NY when its below 0 in the winter and 90's in the summer.
