i was wondering mi boy told me to get a safc . i know wat it is but wast does it do? do it have any efect on the hp i heard its like a chip sort of?

 

I know that it has a few built in monitoring units like volts, throttle percentage, knock, and a few other things but i also think that there are a few tuning programs in there too. I have a friend that has one but im not sure what all it does.

 

The SAFC is an air/fuel controller. It allows you to tune fuel into or out of the fuel map of the stock ecu by up to 50% in either direction. It can help you gain wanted MPG out of an NA or eeking out mroe power from teh TII by adding fuel to prevent detonation and from going lean.

 

wow........ok, so maybe this isnt the best place to be asking this.......basically it is a fuel controller, mostly it helps you add fuel and take fuel away if you choose to for hp gains or fuel economy, you NEED to know what you are doing if you install one otherwise you can blow your motor


i suggest reading and studying up on it before getting one, they can be quite beneficial

 

yea, im picking 1 up cuz my s5 runs to god damn rich, figure get it tuned from a shop over here, and get the car running not so rich, and better mpg, hopefully.

 

English? Please?

It's not much harder to use proper spelling/words/punctuation than it is to hit random number keys.

And the SAFC will help with fuel consumption at high RPM significantly, but won't affect cruise much - you can get some gains, especially if you disconnect the O2 sensor & use the SAFC to tune for slightly lean at cruise, but if you've still got cats, I wouldn't suggest doing that.
