S-afc2

[just2asian]

I know i'll get chewed out for this, but I've always wondered. Bunch of my buddies have turbocharged cars, of course most of them have a SAFC, anyone think an SAFC would do something on a NA car vs. a FI vehicle? Would tweakin with the air fuel make any difference on our vehicles?

That depends what your definition of "something" is. It could make 2-3 whp difference on your setup I bet. Can you tell the difference? Probably not.

It's not worth spending the money when you can use it on something else to make your car go faster.

GO FIND THE FREE MOD!

adjust ya a/f ratio with a simple spin of a cog! (its on the first page somewhere too lol)

S-AFC II's are good to have if you plan to do a lot. I bought mine with the intentions and after having thought out my build.
It's a device that can adjust a/f ratio, which IMO is good. It'll help you get the most out of all your subsequent modifications and overall, when you're ready for adding something serious (turbo, s/c, increasing bore, port, etc), it'll really help you out.

[terrastrife]

may as well just do it the free way, and go something like SMT-6/7 if you want a half decent controlling ability.

or is it that you want the ricey display on ya dash?

[CrawlingEye]

if you don't like the S-AFC II don't like it, but to deny it's function in tuning is just stupid.

[terrastrife]

you can mess with ya a/f ratios for free, why bother paying for it?

sure its not as flexible as the inflexible safc series, but the 3vz in general youll find that above 4k the amount you learn off is very linear... so the free way will be just as good.

[CrawlingEye]

the 3vz tune is a standard tuning, you can only adjust the entire a/f ratio, not incrementally fine tune it.

further more, I don't own a 3vz, I own a 5S which uses a MAP sensor.

ok my bad.. for some reason i though ya had a 6 pot

hmm.. if its cheap, i guess go for it.... only if its cheap.. you can make more power elsewhere for hte same money ^^

I don't think you completely understand my situation. For tuning, I wanted something to tune the A/F ratio that didn't require a laptop and could be tuned in-car on the spot. The S-AFC II allows this. I also wanted something with a measurable amount of tuning steps (the S-AFC II is 11 increments in up to 200rpm increments with 50% flexibility leaner or richer). You do the math, the S-AFC II fit the bill for what I wanted.

As far as making more power elsewhere, for most this is possible, but I already have rippmods headers and downpipe, a full custom mandrel bent catback that's made of 2.25" tubing, a flowmaster muffler, borla turndown tip and flowtech purple hornie glasspack to muffle the sound further. I have my CAI, unorthodox ultra S, new ngk plugs and new ngk plug wires along with a full suspension. I don't quite see where more power could've been made for cheaper, none the less I have a ported, polished, milled for compression, hand decked, 3 angle valve jobbed head sitting in texas waiting for cams before it gets 2mm oversized valves. I think it's pretty easy to say that some sort of fuel management is/was quite neccessary.

[terrastrife]

ah but you never said that in ya first post about wanting a standalone a/f tuning thingy :P

if thats what ya said i wouldve said safc go!

:P

terra the safc2 is not a standalone unit...its a piggyback unit for the ecu...and the display is not ricey...its like that so its easy to see at all times. I got mine for about 250$ off ebay compaired to close to 400 retail? not a bad price for the power gains it can give u if u have a big setup. only draw back is u kinda do need a dyno to tune properly.

i meant standalone as in no need lappy/pc.

^ Then its not a standalone.

Standalones require a laptop/desktop to tune.

[CrawlingEye]

I think he meant standalone in the sense that it works indepently of a computer. I suggested that in my first statement that it was the reason I got the S-AFC II.
