SAFC Tutorial?

I just bought a SAFC for my teg and I was reading through the manual but I don’t understand what to do with a lot of the settings that you can adjust. This is the first time that I’m going to work with an Air/Fuel controller so I’m looking for a tutorial or FAQ that can help me understand what I can and can’t do. The SAFC’s manual clearly states that a “Proffesional” should do the tuning and since I don’t consider myself a pro I’m kinda scared that I might screw something up real bad if I start to change the default settings. I bought the SAFC because I will eventually be running a fully ported and polished B18A head with some wild cams and I want to have a decent idle. Any help will be appreciated. Thanks!
