Are there any maps around for the pylon courses? I get lost on the first one after the first timer section.

The "LX week 1" course on autocross area?
After the first split time you are supposed to drive through the pylon "gates", then around the two lying pylon. The direction a lying pylon points shows which side you have to pass it.
See the attached replay, hopefully is correct path. (I only drove slowly because did not know track)

More maps are here:
