I was just talking for a few friends, tried to search but how does an SAFC work. Like the Apexi one.

Do you just plug it in and it automaticly adjust to proper air/fuel or do you adjust it your self?

Any extra info? I was kinda looking into it as a replacement to the Drag turbo kits, FMU?

SAFC requires tuning. It basically operates off of your map signal and tricks your ecu into believing its either rich or lean a certain amount. FMU's are bad because it adds fuel by simply raising your fuel pressure exponentially. This will make your setup run, but not very well to say the least.

Ok, I might have a guy who will trade me his Apexi SAFCII for my HIDs of my cavalier.

If I do this, will the SAFC (if I have it tuned propery by a shop) work well with the Drag turbo kit to make it run safe?

It should work good if you get it properly tuned :grin:

you can use the safc with that too. You can tune the emanage so its not really needed, but it would work

Ok, was just curious since I already have it.

I just want to try and build a safe reliable turbo kit that wont be as likely to blow the engine as much if at all. Only going to boost to 6-7psi.

just dont go any higher than 8 psi on stock internals.
8psi makes no difference stock internals can do 15psi just depends on the turbo basically you go by how much hp it can handle not how much boost.....a safe area is about 225whp.

safc will work on basically any car, doesnt matter if it is forced induction, or turbo. its an ok way to tune your car, plus it holds its value well, so when you go with real fuel management you can still sell it for a good chunk of change

So if I go with the Greddy kit, do you all still reccoment keeping the SAFCII unit or just selling it. Does it provide any extra info like the current air/fuel mixture like an a/f guage would?

if you go with a greddy kti keep the emanage and sell it. if you want mroe tuning than the emanage allows, sell the injectors and get 450s and hondata

all the safc does is trick your map sensor to fool it into adding more fuel. thats why its called the "hack"

IMO, sell the safc, buy a chipped ecu and run Crome or Uber. get ahold of someone that knows how to tune and get it done right
