Do you have a set of larger injectors? That would help the setup. I would take the deal for the time being.

i can get a set for about $100, whats the most a safc1 can handle 550-650cc. ive been told a safc2 can do 650 but cant find much info on the 1

Are you having any issues with fuel?.
If you have stock injectors, safc will not do much for you, How much Boost are you running?, are you getting fuel cut or having some issues.

Personally, I wouldn't get it, unless you have some bigger injectors laying around.

If you can get a set for $100 and will spend $100 on the safc, why not wait to have more money and go with link.

You only will waste your money.

AFC can do plus or minus 50percent correction. So if your factory ecu was wrote for 450's the afc can do a pair of injectors that are 50percent larger than stock. But the crappy thing is, is that the more corection you pull the more timing gets interfered. I would say afc is truly only good for one size larger injectors (550's)

The differance between AFC1 and AFC2 is that the first one only has 8 points of correction and the later one had 12 points of correction

For a hundred bucks its worth it. Try to offer him 80. Its still a usefull item even after you get dsmlink

I have full dsmlink V3 and still have SAFC2 installed. I use mine for knock sensor gauge and shift light. Afc has nice peak and hold info that u can look back at very easily. Like max rpm and max karman vortex and things like this

I say buy it

im not hitting fuel cut and only running between 14-16 normally. I accidently turned it down to 8 and spiked at 12 smoking on shifts since how rich it was running. My end result with the car over the next year or 2 is only 11-12sec on slicks not going for much more then that.

If the guy won't sell it for 80bucks then it aint worth it. But if the price is right I'd jump on it and buy it man. You can do "blue wire mod" and use afc as a O2sensor voltage gauge, can be used to double check and verify correct throttle angel, has shift light function, volt meter gauge, mass air flow sensor gauge. The rpm peak and hold function is pretty usefull actually. Probably the most usefull and that alone is worth 80bucks. Buy it for less than a bill and you'll be doin pretty good for your self

Has a shift light function? And how did you get it to read knock?

That picture you posted if a safcII. For 100 bucks, thats not bad. A safc I is the old dial button one.

I have one of those, and a maft. both sitting in a box, with a modded chip. save your money and do it right the first time. those are for limited mods, and you will be pissed because your car runs like crap. go link, tuner pro, jackal, warewolf......whatever. just don't throw your hard earned cash away. buy a laptop you can use to tune with, or a battery for the one you have. cost me 100.00 for a battery for my lap top, but now i can run it for 10 hours.
just sayin

Are you talking about the picture in the OP? If so, that's a SAFC 1.

SAFC2 has knock sensor wire. I'm unsure if SAFC does or not. There is warning parameters you can set and yes RPM is one of them (shift light). To tell the guy to just pass it up and not waste your money is not very well thought out. ABSOLUTLEY AGREED if he was gonna dish out $300 for a brand new one from the local tuner shop.

But for 80bucks man? Don't be cheap. 80 bucks aint gonna hardly dip into the 600 he'll have to start saving for LINK

I run full speed density on dsmlink V3, and yes I still have SAFC2 installed. I like to think I know what I'm talkin about as I've sucsefully have cleared 500awhp on a mustang dyno

For 80 bucks I would absolutley buy it. It can do a lot of little tricks for only 80bucks.

Re-read post number 7. Tell me that those features alone aren't worth 80bucks? Yes its only truly capable of 550cc injector upgrade. But that's way besides the point. Its not gonna be purchased for a tuning tool but purchased strickly for the use of the gauges. Volt meter, karman vortex, airflow, O2sensor voltage, throttle angel, knock, RPM. The fact that it can peak and hold. The almighty laptop aint always gonna be there and after that spur of the moment freeway fight or stop light challange its just so convienyent to hit that "up" button on there and see the max values. Don't be dumb, for 80 bucks its well worth the virtual gauges the system can offer

And by no means am I suggesting this as a replacment for link. As we all know dsmlink can't be f#*$ed with. Also the multi button afc is the version one and the round dial afc is version 2

On my old 1g awd, it had very similar mods and the same evo 3 turbo. I had 550's and a safc, it got the job done. I plan to do link this time around because I plan to run bigger injectors and eventually, a bigger turbo.

For 80 bucks, I kinda agree with dsm curse. He is actually making me think about getting one even after link .

BUT, at the same time, if your car is running healthy right now, maybe just save up for link (and/or) buy the safc, but dont install until after link so that you dont't have any tuning nightmares. It's your call.

Most people here hate on anything that is not AEM or DSMLink, but SAFC is not a bad tool to have.
Its a proven piggyback as it was used by just about anyone in the Tuner scene throughout the 90s.
May not be the best tool to use for fine tuning but it gives you a light taste of what tuning a car really is and offers some helpful features(TPS voltage,etc..)
For 80-100 bucks, I say its worth it.
In my opinion the only downside, is the installation. If you can wire it in yourself properly then all you have to spend is your own time, but if you take it to someone else, it can get pricy depending on your location.
Also nobody mentioned that these SAFC units do not depreciate real bad in price if they are kept in good condition.
You can buy it for $80-100 and then a few months later, sell it to a 240sx owner for about $80-100

I used an SAFC exactly like that for a while before switching to a flash ECU. They are useful, but I highly recommend boost referencing the throttle wire with a MAP sensor instead of actually hooking it up to the TPS. It allows the SAFC to work with the turbo more effectively and makes daily driving much more pleasant. The SAFC was originally developed for N/A engines, so they do not take boost into account well if set up the normal way. You have to fiddle around with it too damn much... The MAP sensor trick prevents that hassle and generally improves the overall efficiency.

Hell, no. SAFCs suck to begin with. I have a buddy that just bought one for $30; and this was an SAFC II (WOOHOO!) I could possibly see spending that if it were the SAFC II Black edition that are kind of rare.. Keep looking.

Thats the pretty much goin rate for SAFC 1's these days. They helped me back in the day...and would recommend them for someone who just has minor bolt ons and isnt going for balls out power. I sold my SAFC II a few weeks ago for $150 to a Supra guy Some people cant come out right and afford ECMlink...so why not use what will get the job done for now?

My buddy just sold his SAFCII Black Edition for $160. For the price that this guy is getting it for...I dont see any reason not to get it. Unless someone wants to come out and donate the money to buy ECMlink...

AFC's are great for fine-tuning on the fly.....they're shitty for not allowing any timing adjustment, and limiting you to 650cc injectors unless you piggyback a MAF Translator.

OP, try to get this guy to sell for at least 80-90 bucks. If you score a afc for under a hundred bucks its well worth it man. Don't listen to the guys who are talkin S. Being perfectly honest, afc is only good for a 550cc injector upgrade on our cars, but that's besides the point. And even so, think how many guys on here have set up like E316gturbo, 190lph pump, 2.5"fmic, 2.5ic piping and FIVE FIFTY INJECTORS. And that's really a pretty decent set up that's rather peppy on the street.

And after you outgrow the "light mods" and actually more so start goin balls out, that safc will still be usefull stricktly for the virtual guages. You will no longer need it to pull corection but can still use it for its other tricks. Its very usefull item for under ahundred bucks. Try and score the afc man. They're not hard to install. There is a VFAQ on it.

don't buy safc ever. It's like going to the tv store and buying a 27 crt moniter instead of hd flat screen. Save up for dsmlink do it right the first time. Save money.

This! And the crt tv only gets 5 channels, when the hd gets 1000

So, as you can see, there is absolutely no consensus to if you should or should not get it. You have to decide if you need it now to get you through until you can afford a complete tuning solution, or if you can put up with running the 450's on lower boost for a while longer to save for something better. Having used both, I would recommend saving up... Even a flash ECU, a Tactrix cable or 2.0, and EcuFlash/Evoscan is only a couple hundred more and will allow for proper tuning (plus a whole bunch more cool stuff, like launch control, anti-lag, speed density, and NLTS)

would i be able to use a set of evo 8 injectors with it for now. a friend may have a set sitting around and i read they are around (read on here they are about 560-580cc)

Absolutley man. SAFC will have 8 points of correction and 2 maps, a low throttle and a high throttle map. You'll set the correction points to be 1k 2k 3k 4k so on so on and you'll end up close to about - thirty percent correction. Car will run fine

Safc for $100-$120 is a steal and a good price everyone in colorado tries to sell them as if they were new for $190-$200
