To be honest I don't really yet know exacly what AFR does... I can read about it in my 9Z manual, but that hasn't helped me really understand it...

AFR stands for Adjustable Function Rate and is used to adjust the throw and operation curve of the lever, switch, or slider... Expo is also somehow tied into AFR on the 9Z... I was hoping Chip would add some better explanations of the finer points of 9Z programming...
