Cold start spark advance question

I've screwed something up, now on start up my spark timing is barely enough to keep the motor running. When the coolant temp reaches 44.75C, the timing goes to where it belongs, and all is good. In the scalars, I see that Spark advance cold disable is 44.75C, as is Spark advance hot disable(44.75C) What should these values be, and what is meant by these parameters?

Re: Cold start spark advance question

I found it (730 cold spark advance from guide book and FAQ) I had imported a new main SA table, and the 400,600, and 800 rpm @ 100 kpa was 6 degrees. Mine needs 25 deg in those cells.
