I have a noob question. I have no experience with ECU tuning, and I'm curious what it really is. Altering timing? fuel? Tricking the air flow sensors? Etc etc... I really don't know. Is it safe? Will it screw me when I'm due for an emissions test? Can someone enlighten me.
Oh and BTW, can someone tell me where the carburetor is on the FR-S, I can't see it in any of the engine bay pics.
Thanks
