Well, I hooked up my SAFC to the SR harness to make it driveable since it was running extremely rich. I don't know what the set the "In" and "Out" setting's to on the sensor type, I'm using a KA24E maf. I looked in the SAFC manual and it said HW-5 I think. But anyways, if anybody can help me out that would be nice. Thanks.

Alright. Well I had the SAFC hooked up tonight, I forgot the MAF signal wire that goes to the SAFC. I got that hooked up and the car idle'd perfect. But when I would give it gas it would want to die. The RPM's wouldn't go up at all, just down. I need help figuring this out so I can lean out my idle. Thanks.

you set the throttle voltage at WOT and closed like in the instructions before starting it right? my friend forgot to do that, i guess its a stupid/easy mistake

I don't mean to dog on your setup, although I really do hate the idea of having a "fuel controller" that works off the principle of manipulating MAF sensor signal.

I can't really help with your SAFC but sounds like you have some other underlining problem that needs to be addressed since you mention your car running rich. Definitely get a fuel pressure gauge on it. It's not too uncommon for the fuel pressure regulator diaphragm to fail when using a higher pressure pump, which would cause your rich condition.

I always ran 2 in 5 out and set to hot wire. And low throttle start at 30 and high at 70%. I ended buying a FC though cuz i didn't like the way car ran at all. Iyt would run good but every now and then i would get popping in the RPM while hitting hit. I was running rich to before i got it tuned. Remember you can't run any higher imjector then double what the stock injector is. Also i told you 2 in 5 out but thats just what i have heard, i haven't seen anything solid that says this is best voltage, but that was with z32 maf.
