This Apexi AFC came installed from the previous owner of this car. He gave me a vary vague explanation of it so I am wondering if anyone here can give me a more detailed explanation??

Also any tips for its usage(moving the dials etc.) would be appreciated!

Thank you!

p.s. sorry about the poor quality pic.
