I am wanting to know the pros and cons of both. Id like some feedback from folks with either of these. I am looking into buying one and want to make sure I get the right one. thanks in advance for the help!

 

I had a f-con on my turbo 2. I would recommend using both at the same time.

HKS F-CON
Pro: Fuel according to rpm AND boost levels, set a little rich for safety reasons, guaranteed fuel map up to 15 psi
Con: Does not consider what kind of mods you have in your car, can't compensate for different size injectors

APEX'i S-AFC
Pro: Adjustable according to the mods you have, show vital info of your cars, allows you to use slightly bigger injectors
Con: It's dependant on RPM ONLY! Does not know the difference between WOT and 50% throttle.

I would get the F-CON first as a safety mod and then get the S-AFC to fine tune the fuel map according to your mods.

OK, now price, i looked at the super afc and the MSRP was 419 bucks. i headed over to the HKS website and the F-CON was 1240 dollars!!!??? is that right? if so i just made up my mind, if i wanted to spend in excess of a thousand dollars id go haltech or wolf. someone tell me i read something wrong or looked at the wrong part!

 

How about HKS Super AFR?

 

what will happen if I use different size of injectors(with f-con)?

 

That's just the retail price though. You could find used F-Con and used S-Afc for about same price.

This debate used to always pop up on the old TeamFC3S.Org list all the time.

IMO, the HKS PFC F-CON is overpriced.&nbsp The S-AFC does all the things the F-CON does + HKS GCC for another $400.&nbsp HKS lost a LOT of money due to the A'pEXi S-AFC being more price conscious.

The added boost sensor doesn't mean squat.&nbsp The S-AFC, when tuned right, will give you more flexibility to your vehicle.

Don't bother with the F-CON - it's a waste of money.&nbsp Go with the S-AFC, and be happy you're got several HUNDRED dollars to spend on something else...

What sort of HP gains can you expect from an s-afc on an N/A with minor mods? I like the idea of having control over the a/f and not having to rely on the OEM ecu—I think my electric toothbrush has more computing power!
