This track should be a pretty good race once you get done with it.
Sharing here on 2 of the issues you asked about above so everyone can know how to do i:
I figured out the pit limits - see my thread on it in Steam on the Discussions page for RTB.
Also, I figured out the map problem. If you delete the "maps.ini" file from the data folder, and delete the "map.png" in the root folder for your track, AC should create a new one for you automatically.
As for the AI-line, (1st IIRC you need to enable the AI app in the settings and then) turn on the AI app in the right sidebar of the AC game. Then record some laps (you can go slow and smooth), then stop recording and do one for the pits. The 2 record buttons for each are on the right side of the AI add-on display. Unfortunately, for me, the AI is doing all kinds of crazy stuff and I think I know why - when I look at my track in KS Editor, the red lines which are supposed to be the track limits cross the track all over the place and are way off line. But I don't know how to fix that at all.
