has anyone here used apexi single button afc before? what's the difference between the single button and the 5-buttons? is the single button easy to tune? i'm deciding to buy either of these two afc to tune my car but heard from a mech that it's better to get the safc 2 or neo as they are more accurate, of course they are very good but i'm on a tight budget.
please give me some ideas to go about this, thanks
