another na-t question....
with stock compression, do you really need to use fuel control like the apexi safc1/2 ?
i searched and found out that you dont really need to as long as you upgrade your fuel pump.
i just want to confirm this.
tks guys!!!

yeah, you need something... bigger injectors + walbro fuel pump
Indy... you're local to me in malibu, right? (socal at least?)
I'll give you my AFC I for cheap ($100 sound fair?)
I'm not sure if it's working or not... I bought it this summer and never used it. If it doesn't work, just give it back.
PM me if you're interested.

For very low boost, I would say it's not "necessary" but your car will just lack tuneability. You'd have to play with fuel pressure w/ the boost. I'd say if you're not going to get an afc at all, it may be kind of ghetto, but at least get a FMU(for a low boost app.). But with deals like ^^^ for an AFC for $100, who could pass that up?

I've been running an SAFCII with 5psi and for the most part the SAFC hasn't been able to do much because my ECU is interfering heavily.
About a month ago I received my AEM unit and attempted an install (the dumbass that I am, I completey removed the SAFC first).
To make a long story short, my first AEM install attempt was unsuccessful and now I'm running no fuel management at all.
I've been keeping an eye on my wideband and it actually looks pretty much the same as it did with the SAFC.
The reason the SAFC hasn't worked well for me is I have an OBD-II ECU which is allergic to boost.
Since you have OBDI (If I remember correctly) the SAFC would be a great tuning tool for you.
I'll be putting mine up for sale shortly.
$200 shipped sounds fair to me.
Good luck with your project.

i would absolutely not run without it. obd-ii cars have run into all kinds of problems with tuning but the obd-1 cars love it. The only problems is in the region right when you start to boost. The computer doesnt really know what to do so it dumps fuel in creating the usual off the chart dip in the a/f chart. Otherwise, the safc will get the a/f curve flat as an arrow (read: safe power)
Those are some great deals on the safc's
Drop me a PM if you want to get rid of it and you wont have to bother with posting it for sale =)
is it by any chance the special edition black?

i'm kind of in the same position as you. attempting to put in my aem and sensors which is the only thing hold back my car from going on the road. but luckily i've meet some friends who came and helped out quite a bit. just wondering how you're planning on tuning. the traditional way? or boost compensation?

I just spoke to one of my aem tuning buddies with an in house dyno. If youre in socal and need some help with installing/tuning drop me a pm and i can give you the number of my friends shop. They have an in house dyno with WB available and they do aem installs/tuning all day long. i was telling reamemiya about them in case the problems never went away. Let me know if you want their contact info. I asked specifically about the obd-II difference and he said it shouldnt make a difference at all and they can fix up whatever problems you have.

If you want to read some of my preaching, search for posts by me containing "MAF"

All OBD-II related problems can be forgotten with AEM because once the stock ECU hits the trash-can, OBD-II goes with it.

It won't be perfect but it'll be good enough for my 8-10psi on stock CR.
From looking at the .cal, it looks like they tuned him up to 6psi and then used boost compensation from there.

pat: the hks unit isnt so great. Go with the safc. The safc for $100 is NOT a bad deal at all. In fact, its a great deal.
I think consensus among dyno tuners at least that ive spoken to is that the hks afr is junk and a few of them have actually said to pull it out, try to sell it to recoup the funds, and get an apex'i safc
