Have a Nice Day? Newbie Question about S-AFC computer


I know the S-AFC is a fuel computer, but that's where my knowledge ends. What exactly does it do / can you do with it? Also is it a worthwhile upgrade for a stock vehicle, or is it better for one with minor upgrades (i.e. exhaust or intake)?

Thanks All,

For a MY00 car, I'd say it's really not necessary. I have one on a MY00 and I never have to correct more than a few percent. It runs slightly lean at the top end and a little rich down at the bottom with an intake & exhaust. Personally, I'd say you'd get a bigger bang for the buck by getting headers, especially since you need an EGT gauge to go with the AFC to tune a MY00-01 car.
