Questions About Coldstart 1&2

When does each apply? My understanding is that cold start 1 is for the first attempt at starting and that coldstart 2 is either for the second attempt if the first fails, OR it is the warmup correction factor once the engine is started. Which is it? I have tried adjusting the values while live tuning in the car with the engine warming up, but the changes don't seem to have any effect. That is, when live tuning, I can track the coolant temperature gradients in eftersta_fak2, and change the values, but there is no effect on AFR.
However, if I change the values in either coldstart 1 or 2 BEFORE I start an ice-cold engine that sat overnight, it will either chug or stall or fail to start period.

Any insight or advice would be awesome.
Thanks,
-Cm
P.S I know these questions are better suited to ECUproject, but the site is dead. Cyber tumbleweeds and I are all that traipse that forum
