SAFC -- Will it work?

Phant · 03-17-2009, 10:45 AM

As the title states: will an SAFC work with our motors? Or will the OBD-II jus' continually relearn the changed ratios/adjust as it deems necessary?

Wantin' to tune out some flat spots (2400-2900 rpm, etc) and make sure I maintain a proper A/F ratio throughout, and this seemed like the least expensive route to take... provided it works.

If it won't work, what's the best route to take? ...hoping to avoid the standalone/more involved piggyback-type scenarios for the time being...

SAFC's have been used on 3SGTE's for a long time...

mr220v · 03-17-2009, 12:14 PM

I would step up to a 1zz power FC.

Phant · 03-17-2009, 02:11 PM

3sgte's aren't OBD-II though, are they? I jus' keep reading how SAFC tuning doesn't work well for OBD-II cars 'cause the ECU keeps relearning or somethin' along those lines...

Back then when I bought my engine the former owner said that it has an SAFC and with it and the SARD filter, and custom made exhaust it's making 217 horses.
I dont know how much of that is true, and I'm still having problems with unleashing the stock 200 horses.

I didn't ever get the SAFC though, I guess it was lost somewhere in the shipping procedure...

SnowRocker88 · 03-17-2009, 03:33 PM

Oh, wait...you're asking the opposite of what I thought...

haha, I had the idea you thought SAFC's were just for OBD-II cars, sorrry.

My 1st post in this thread = EPIC FAIL

i had SAFC on one of my S13s, would not recommend it (boost creep, couldnt figure it out...)

Stupid Ass Fake Controller? Save your money and a decent EMS. Even a PowerFC is pretty bare bones when it comes to EMS's but 100x better than a SAFC!

Stock air/fuel ratios arent great but they work and are safe. With a SAFC chances are you will end up hurting more than helping.

I see i see...

RedTop BEAMS != OBD2 officially at least, it's a sort of in-between version

Servin · 03-18-2009, 11:07 AM

No BEAMS is OBII. Its just Japanese spec so it uses different standards.

mr220v · 03-19-2009, 09:38 AM

It's a different standard and lacks a few things. Can't use a US scanner with it either.

I'm not a fan of piggybacks if for no other reason than it involves hacking into a harness I made by people who may or may not know what they are doing. When they mess up, it tends to fall back on me.

In the case of the beams, I think it would also be desirable to have control over vvti as well. Something that can't be done with an safc.

..can't use a Uk OBDII scanner with MK 2 either though the Mk 3 is OBII as fas as I know which creates some problems with certain aftermarket ECU's

Don't know much about the SAFC at all but it sticks in mind that they aren't great with the 3S engines. I will be proved wrong though.

Beams isn't OBDII, would make life allot easier if it were.
