Just wondering, i was playing round with the time bit on the timer and accidently went up to the af ratio and changed that, there seems to be 3 different set of numbers you can change, does changing them affect the af ratio? what are they meant to be, i know the af ratio is 14.6-14.7 but after i changed one of the settings its at 14.4 now when idling, how do i change it?
