I havent run the VSF1 on a Velodrome but on a normal banked track I started off around step 10 and went up 1 at a time to half throttle and then 2 steps at a time to 3/4 and then Max freq the last 1/4 throttle.
I have the 40144 Kit and for a starting setting I used the one listed on the KoPro Po site, you can increase or decrease the setting based on what you like.
At the front page put scrowling arrow on the Support heading then click VFS2000 Help. It lists the standard factory setting profiles plus several types of racing profiles. When you click on the one that's closest to how you use it, it will display the list with steps and settings.
Some of the settings I wasn't to clear on so I emailed KoProPo, got an email back the same day.
Yeah, I too email Ko and wow quick reply. Vary Good.
I would start with one of the mod profiles, but turn on the throttle response to to 9. This gives the least amount of throttle response for no traction conditions."
