Can I use the AFC for fuel to compensate for more mods for now?? I mainly want a full exhaust (including midpipe) and intakes, that will lead to over boost thus I need a new computer. I cant afford a Power FC but this is more reasonable and more in my price range?
Comments and/or suggestion welcomed.
Thanks

 

No. Buy the PFC.

 

Some reasoning please??

I cant afford the 1200 for one at the moment its way to expensive. I mean if this will at least solve the fuel problem for now its worth it no?

 

ignition, etc, other factors invovled

 

Its not worth it. Keep the cat on until you get the PFC.

 

I've seen first hand an FD make 380 rwhp single turbo with a fuel pressure regulator and a S-AFC. If your going to use the stock twins, I see no reason why it would NOT work. I ran with it for over 2 years on my FC boosting the **** out of it and running higher fuel pressure without every having issues. It's best to get a PFC, but in the meantime, an S-AFC can fix some of the fuel issues you will have.

 

Yes I plan to use the stock twins for quite some time. Yet I wouldnt mind getting 12psi out of them or just stock boost but with more fuel to compensate for removal of the cat. I have to remove the car since Im getting rid of all emmisions ****. BTW any pics where the stock fuel regulator is? Ive got my motor sorta torn apart so its no biggie to get. Thanks

 

Just save for a PFC, don't waste the money on a S-AFC only to have to upgrade it later.

 

I would not be upgrading anytime soon, easily another 6 months or more until I can even think about it.

 

It will happen sooner or later, might as well save yourself the trouble, besides what is the price difference between the two $400-$500???
You don't have to get the commander, plus you could sell your stock ECU if you really wanted to or needed to.

 

If you have money for full exaust and intake then you have money for a PFC. Buy the PFC first, then the exaust etc.

 

Ive heard the I'll clog the cats without the emmisions stuff. They already have 130k miles on them if their not clogged already. I already have most of my exhaust already, Im only missing the midpipe and tip. Intake and DP I already have.

 

Do what you want. If the S-AFC can be had for a cheap price...why putt around for 6 months. If your buying it new...might as well get the PFC.

 

start selling stuff around the house!

think whats better.
waiting for the nice pfc that can tune the engine well
OR
putting the s-afc in and maybe blowing your engine, causeing you to be in more debt of the cost of the pfc.

so in the end just wait, no reason not to wait. you will get it soon.

 

A new engine will cost more than a PFC, correct?

 

Alright Alright I get the point =P

 

they're full of ****. I'll say it now...if tuned right, the AFC will do fine as long as you don't turn the boost up past 15 psi. Ask Dragon about his turbonetics 60-1 with a fuel pressure regulator and S-AFC. Or IGY with a TD-06, fuel pressure regulator and S-AFC. Both cars ran for over 2 years on an SAFC. Dragon's car ran for over 2 years and didn't blow because of running lean. It blew because it lost a water seal. IGY's engine NEVER blew up on that setup.

If you can access a dyno, you can get "reliable" a/f's and save up for your Power FC. But I guarantee you that most of these people talking bad about the SAFC couldn't tune their own PFC's... S-AFC is easy. You just have to be sure your a/f's are correct....just like on the PFC...you could put on a PFC and still blow up the engine.

 

why don't you get a remapped ECU like M2, pettit or G force ? they cost arround 450 used and run great with all the boltons. thats about $150 over a price of a S AFC.

 

Thanks JSpec, I have access to a dyno (Petit), thats where I plan to get my car tuned. Thanks for everyones comments

 

I'm guessing Petit has a wideband in the shop? Get a boost controller (Home Depot style works) when you get the mid pipe!

 

Midpipe = pop Off valve or Turbo porting or else (Boost Creep) nothing you do with the AFC will prevent it.. it's a matter of the wastegate not beeing able to get rid of enough exhaust fast enough for you... has nothing to do with fuel, except that when you hit 15 PSI due to creep you need more fuel... I say put a pop off on ..250 Max, set it to 13 PSI and go on with your life...

 

Well ya I was planning to do a manual boost controller ( I like Damians set up). Then move on from there. Could I not get an aftermarket BOV set at 13?
