i have an safc but i want to know if its gonna do the job for its price or should i use the f-conn

 

For the money, the S-AFC does what you need.

For real control you're going to need a stand alone.

 

I actually have an F CON that I just picked up off of ebay..... I wired up my AFC last night. LoL. In my opinion the F Con is kinda crappy, it was actually making my car run so rich in the midrange that it was hesitaiting. It has a few adjustments that can be made but i personally think the safc is a better bargain.
