Hey i was wondering what you guys could tell me about F-con's. Are they any good? what what exacally do they do? Would i see any power gain in just installing the unit?

 

they are for turbo only...

but not worth the money. get a s-afc instead.

 

Well i can buy one for $450. Is it worth it what does it do, would i see power increase with it? its for my 87 turbo 2.

 

get a s-afc for $290. spend $50-100 on tuning. and it'll give more power. and you change it every time you add a mod. the f-con you can not change.

 

the older fcons have a potenteometer inside that you can change to accomidate everything from stock 0 to 9 witch just opens the injectors 100%. i had one on mine and i was running 10-11psi of boost with an upgraded turbo and a racing beat turbo back, and it was pig rich.
however, the safc is cheaper it will let you put bigger injectors in and it is more tuneable. unless you get the fcon under $150-200 you would be better off with the safc, or an emanage.

the s-afc is actually $315 at www.rx7store.net There is somewhere you can get it for $290 though.

 

What is the $50-$100 tuning for???

 

An S-AFC should be properly tuned, otherwise it's just a flashy expensive screen. Most people's "street tuning" won't be anywhere near as good as a proper dyno tune.

 

so your sayin 50 to 100 bucks to have someone tune it?
Is it hard to tune yourself?

 

That's half an hour to an hour on a dyno with a wide-band A/F meter and someone who knows what they're doing. This is the safest and most effective way to make any changes to your mixtures.
