To start, you need to set your t-stop rpm. This is a big factor in how much time you put in the stop. I would start out with the t-stop rpm at 4200 rpm.

Set the first number in the timer to .1 sec and put the second number at about 2 sec. See what the car runs and adjust from there. If it runs too fast add more time, If it runs too slow take some time out.

You will want to keep your t-stop timer between 1.5 and 3 seconds so you may need to adjust the t-stop rpm in order to achieve this. This is very much a trail and error process.

The way you check the t-stop rpm is to stall the converter while the t-stop is on. On the 450 box, in Pro mode, if you press and hold the 0 key, it will kick the t-stop on and keep it there. Press and hold the 0 key again to turn it off.

Once you get a handle on it then you can use a weather station and some software to adjust based on weather changes. I wouldn't worry about that part just yet.

Hope this helps.

BTW. Does the 450 box let you shift your TH400 or are you using a different box for that?
