When you start doing your own tuning, go to evotuners.net, and we'll get you started on the right foot. We have a write-up on how to use the S-AFC from scratch. It's what I used to get started, and I had no help locally, so it definitely works.

I will discuss/explain everything with you tomorrow at the autocross.
