This PCM basically has 4 idle speed tables and a few adders. If you are using a 4L60e and A/C input to PCM, you will have to adjust all 4 tables. If a 700R4 (4L60) and no A/C input, you just have to adjust 1 table and maybe an adder for idle. The initial flare up doesn't last but a few seconds. The temperature based idle takes however long it takes to warm up from cold and the initial rpm is higher the colder it gets. See attached screenshot for table locations.
