How do I setup my SAFC to run with an open air blow off valve? Its an SAFC II on my redtop SR. Stock maf and injectors(if that matters).

Its called the Dec Air Setting. It must be set on the very first cold start of the day. Check the Airflow % of NE1 RPM and Airflow % of NE2 RPM. In the Dec Air setting, Have throttle at 1%. NE1 reading should be set to your Airflow % of NE1 RPM. NE2 should be set to your Airflow % of NE2 RPM. If you cant understand this, than i suggest you open the manual and read.

Thanks, I am just learning about all of this stuff. A lot of that manual is extremely foreign to me. I will set it now.

safc is a cheap way to get by for tuning, if you plan of doing small upgrade from time to time then get it. im just basicly using it becuz the sr runs pig rich on stock boost. you can tune your car yourself with afc with the help of a wideband.

but if you start going crazy, big turbo, monster size cam or dumping all the good stuff all at once then go with a stanealone or ecu reflash.

The only proper way to tune anything is on a dyno. Street tuning may get you by, and can work, but is very unsafe, without having someone else drive the car for you.

The correct solution however is to actually get your car tuned, or for you to run a JWT or Enthalpy ECU.

Why risk it?

You could crash your car, kill yourself, wreck into someone else, get a ticket (for speeding, wreckless etc etc)...all of which are QUITE a bit more expensive than dyno time....

Usually between 80 and 120 an hour for self tuning.

Most decent import shops with dyno's usually have someone capable there as well (or at least where I'm from, but I assume LA as well). May cost more though for someone helping..

OR

Get a used JWT or Enthalpy ECU, have it work awesome out of the box, and spend less money.

i have seen on other threads that these setups might have your car running lean though. is this true? i've also seen other people say that they had to use an safc in conjunction with the enthalpy or jwt tunes in order to have it running right, but this sounds like too much money for me to spend right now...haha
The problem is, in my experience, that people with ROM ecu's not working well typically have other silly issues with their car as well (vacuum leaks, timing, etc etc)....so that is what causes the car to act funny.

I have seen some cars, both with JWT and Enthalpy ECU's require a 'slight' change in fuel pressure (2-4 psi) at most, but again, that may be due to other issues (FPR's, gauges, etc etc)

Get the JWT or the Enthalpy, plug it in, and go nice sloppy burnouts and enjoy the car :D

quick question, If you're just looking to run a small amount of boost say 7-10psi could you just run on a piggyback setup such as the Apexi SAFC? And get a standalone when you're ready to turn up the boost?

By the time you buy a SAFC, install it, and then attempt to tune it, you will still only be limited to a stock setup....

Your best bet would be save your hard earned cash, and spend it appropriatly when you have enough. An SAFC on a t25 stockish car isn't going to make your car become any more faster, while at the sake of OEM reliability. You may be able to get some more MPG by leaning it out, but the money you spend on the SAFC > saved gas money.

I'm not looking to make it like super fast running on a piggyback setup. Just enough to make the ride more enjoyable until I get a standalone. So I could just have a stock setup with a SAFC to fix the lean issue caused by the turbo? and the piggyback setup I will be running 7psi which is enough for the time being.

I guess I'll be blunt:

Don't waste your time with an SAFC.

:D
