Re: really AFCs blow the engines?
with an afc you are tricking the ecu into seeing different vacuum reading then the motor is acutally seeing. So when you take fuel out you make the ecu think you are running more vacuum this less fuel. the problem with this is the stock ecu will run more timing in higher vacuum readings. So when you scale with the afc for bigger injectors you end up advancing the timing, more timing means knock and knock blows motors

Walter you can adjust timing with Emanage but you have to buy extra features to use the timing and they cost a lot of money. around $800us so really you could buy a chipped ecu $200 and then pay someone to tune your car for around $200-400 depending on what they charge and you still saved money and have a better running car.
the people running afcs safely are not running very much boost that = no HP. I know your gunning for your friend with the STI so your going to need a chipped ecu and crome so you can run a manly setup.

i was running 13psi and had not many problems with the safc but it really isnt great managemant. I was able to get away with more than you guys typically will because the safc doesnt cause the ecu to advance the timing, it has no effect whatsoever.

About the money yes, the emanage is very expensive, and i would like not to pay to other guy for some day to tune my car, i would like to do myself
(if a read the complete wiki from PGMIF.ORG , i will learn to tune a ECU? cuz i've seen that the wiki has great info but i dunno if here there are all the necessary for to know to tune a ecu). i know that with a safc you can to adjusta the 50% +/- the capaticy to your injectors, right? but then, if you can largest injectors , you cant to ajustar the 50% +/- from those injectors? (i know you will need a better fuel pump) ...
ey brothers, ty for your answers. i appreciate it.
