if you're really interested in learning about 'us', you're going to have to realize that it may take a while to learn a useable amount... well, at least more usable than 90% of the riceboys out there who like to throw engine codes around and 'turbo' this and 'nos' that.
best thing for you to do is hang out with some knowleadgable import guys or start buying magazines. most likely you're not going to pick up much from a tech forum.
