some stuff in there is accurate, most is in its correct context.

temp modifiers are normally used to account for changes in air density. colder air is more dense, therefore has more oxygen and needs more fuel to maintain whatever AFR is being commanded. you COULD use a temp modifier to add/remove fuel due to mixing/vaporization issues, but if the O2 sensor is active and being used, it will only be a temporary change.

normally, you would change the target AFR to reflect mixing/vaporization issues, that way the temp modifiers are correct even in this scenario.

you may see some benefit to bringing coolant temp compensation back into your calibration, but it would be entirely application specific. some engines don't need much additional fuel because of low temps, others do, the exact combination of components will determine how much is necessary. if your O2 trims right around the O2 activation point differ in an otherwise identical scenario at full temp, then that is a good indication of how much change would be beneficial in the coolant temp compensation.
