I bought a new s-afcII and installed it today. Took about 30 minutes to install. If anyone is interested i will post instal notes and wire colors for the aveo hatchback 5 speed. I can give you other models, but it wont be as fast because they are different colors and i will have to pul up the ecu pinouts. Now just need to tune the whip... :twisted:
whats an a-afcII??? post pics and notes
ooo.....so what does this let you do?
Its a fully adjustable piggyback air and fuel management computer. It intercepts and modifies map sensor signal to allow you to tune the vehicle it is installed on. You can add or remove fuel point by point at every rpm, and adjust it by throttle position. This will allow you to squeeze the most power out of your car that you can. If you add more mods, retune it to have that mod take full effect. A lot of turbo eclipse talon guys run it, honda guys, i ran one on my avenger so i could tune the nitrous safely.
It will display on our cars:
manifold pressure
throttle position on a 0-100% scale
voltage
tachometer
and it will display active air fuel correction
this is the new one that just came out, it replaced the afc2. This is the afc neo. Really, same thing, but has a built in vtec controller for the honda guys, and a color screen.

hmm, so are you able to squeeze some power from the stock engine now? So now we have a way to actually tune our cars for turbo, correct?
right, turbo, nitrous, etc... If you are going turbo, for instance, buy a higher pressure fuel pump, larger injectors, and then tune it with the afc. I will post the amount of hp i am able to squeeze when she gets on the dyno in a few months, im planning on just street tuning it right now when i get a wideband af gauge.
car runs alright?

Info for the 04 hatch auto would be killer too. Much thanks.
umm i thought brian tried this a while ago and got nothing out of it so he sold it to his brother.....now does this combat the ecu advancing the spark when you adjust the fuel? if not i dont see how it can be helpful for FI....
Hp you will gain with a SAFC II on a stock engine w/o forced induction= 0HP
Thats right folks it been done. no gain at all. It will only help you trim or adjust fuel levels if you are boosting. You will not gain 1 HP from this on a N/A engine.
In theory it can work once you install some headers/intake/exhaust. A dyno and wideband along with a knock sensor would be needed to test this though.Quote:

Turns out by modifying the MAF sensor, I was also modifying the timing. Advancing it at the same time as adding more fuel which is where the timing needed to be retarded. setting the MAF back to zero and only adding fuel through the injector pulse width modification worked much better. By retarding timing in the upper boost range, I was able to safely run 8psi but ran out of fuel as my injectors would go to 100%. Eventually, larger injectors and tricking the MAP to think the car had 33% less air than it actually did made it run really good. I tuned past that up to 17psi which is where more boost no longer would get me hp, but that's past the scope of this post.
Congrats on trying the SAFC. Even those of us who don't expect much results, would love to see the results posted. Dyno graph with air/fuel ratio please. :)
well that sux.....damn we got to get a turbo setup going.....they already beat us down in south america......so wahts keeping us from doing it besides the money?
A good way to tune is the only thing stopping me. Have everything else.Quote:

also brian, you said the safc will not yield any HP on NA, but it would with turbo, why isent anyone trying this?
I was referring to my Impreza which started out with 110hp 1.8L engine, and then boosted. By the time the e-manage went on I had a 2.2L engine with the turbo. When I sold the car, it had a 2.0L engine actually built for boost.Quote:

sweet man, go with the FD, the rx8 is cool, but FD has such a bigger aftermarket. just cause it has been out for a while. Either way great choice. i love rotory, i had a FC 89 gxl. Great drift car, and the power is freaking awsome. now i am driving a 240, and IMO it is very well balanced, but i miss rotory power.
good luck
2nd gen has style, though... 3rd gen has those ugly ass Taurus tail lights...
please post it to me... really need it...
