Like I said I tried to search but nothin....I hear everyone saying that they have a s-afc...well, what is it? And what does it do?

 

S-AFC is a fuel computer. What it does is control your fuel injectors. So if you are running lean at 5000-8000 rpm, you can have your injectors use more gas so you don't run lean.

It's not a replacement for the factory ECU (da brain) it's more of a piggy-back. It just alters the signals going to the ECU so the ECU sends out signals for the injectors to use more or less gas at any given time.
