Can't Lean out With SAFC2. Help.
I installed a SAFC2 about 2 weeks ago. I just installed my wideband today. I was hoping someone can help me. Read through the "how to" for this and didn't see anything that was close to what mines is doing. My mods are in my sig. I'm also running Stg 1 injectors because i was running too rich when i had the Stg 2's in with the PTP FPR mod. Seems like i can't pull any fuel. tried at a moderate pull of 10% at HI Throttle. I'm doing a 10 flat AFR. So I pulled it again at 20% at HI Throttle same thing. My throttle points are 10 LO and 45 HI. I don't know what to do. I even pulled at 30% at HI Throttle and same thing. 10 AFR. I'm boosting at 18-20 psi. Please help.

I'll double check and triple check the wiring.tinctorus said:well either you have your map wire hook up wrong since thats where your pulling fuel from

Could the map be hooked up wrong and the throttle percentage still work. I hooked it up according to the "how to". I will still check the wiring to be on the safe side.
with that fuel mod you still may be getting way too much fuel. I personally would have taken the 75psi mod out and used the S2 injectors then pulled fuel from there. If that doesn't work then I dunno what to say as long as everything's hooked up right there shouldn't be any issues
i doubled checked the wires and i had the map wire hooked up to the tps wire. i rewired and everything works great. I'm pulling 16% @ Hi Throttle and my AFR is 12.x to redline.
I do have one question. My car is getting really hard to start. It went from starting in 2-3 seconds to starting with 2-3 cranks. I took the fpr out and cleaned it. No dirty gas came out. I also took the sensor on the side of the throttle body(not the tps) and cleaned it. My fuel pump makes a really loud whining sound. I thinking of changing my fuel pump to a walbro. Is there anything i can do to help my starting?

its just summer gas mine is doin the exact same thing man its taking longer to crank over
also try not taking so much fuel out you should have it aroune 11.5-11.8 at redline

I hope so. I just got the car a year this month. It didn't do this last summer. I kept hearing about this summer gas issue. I guess I will wait til the fall to see if it changes. I will tune to 11.5 AFR. I was thinking return line in the future.tinctorus said:its just summer gas mine is doin the exact same thing man its taking longer to crank over

I would switch to a walbro. When I had the ptp fpr mod, it worked great for about 5 months then my pump started whining to before it went out. So if you could get the walbro and do not put the fpr mod in that one. I did that and I had too much fuel.dhinez said:i doubled checked the wires and i had the map wire hooked up to the tps wire. i rewired and everything works great.
