The fueling strategy is still based on the SD algorithm and intake air temperature is one of the key parameters to calculate the actual air density.
Calculating the air density for 85F (30C) and -4F (-20C) for dry air at 100kPa (approx MAP at WOT at sea level) you get ~1.15kg/m3 and ~1.37kg/m3 respectively.
Therefor the air density will be over estimated by approx 19% and thus the fueling will go rich by a similar amount to match the over estimated air density.
[ECM] 44280 - VE IAT Factor would be the table to tweak this if it becomes an issue using this strategy.
