PCM codes, cold/warm weather
I was looking at a list of PCM codes and noticed that some have warm weather applications, and some for cold weather...
What is the difference in the programming?
I have two PCM's, both out of 99 trucks sold new in Florida and they both have a cold weather PCM?

The XLE4 is listed as cold weather. The FUT4 is listed as warm weather. Both are exactly the same EXCEPT that the XLE4 has a high idle strategy when cold.

I've run across a couple of them while tuning, but as to the rhyme or reason of it all, who knows?
It's nothing to sweat over though as nothing else of consequence is changed in the tuning of a "cold weather" calibration and anyone with a FUT_ PCM code gets XLE4 on a chip anyway.
