Hey guys i was ondering what my options are as far as AFC's go, i was considering getting a used apexi safc from a friend, but i just got a new laptop and i was ondering what my options are as far as something that i could hook up to my new toy , i dont have any big plans for my car in the future like turbo or supercharging (yet ), but i would like to be able to tune my a/f ratio and possibly something i could use on a future project car.

 

I have the safc II, gained 10 hp and 15tq from it.

Very satisfied, spent about 175 on the afc and 150 on tunning.

Dnt bother will a stand alone system like a laptop hookup unless your making a race car. Waste of money in my opinion.

 

What about the HKS AFR???

maxspeed how far was your a/f off?

Ill probably street tune my car and use a wbo2

 

AFC is not an air fuel controller, it's an air fuel convertor. that and and learn as much as possible, we cannot make your decision for you.

IMO, VAFC - II is best way to go.

First off, you need to find out and see how much you need to tune. I.e get an accurate a/f plot.

 

If you want to be able to mess with the a/f get a piggy back like safc/vafc and a wideband wich will tell you the a/f and then you can tune with the piggyback. They compliment each other nicely but like mentioned above look around and learn as much as you can before messing with your a/f
