S-AFC II install S5 n/a idle prob
I have searched for the last hour on what this problem is, so I need help. I just installed my S-AFC II and it functions. I performed the initial setup and now my car idles like **** and seems to run poor. I have it set as Flap 6in 6out, 4cyl arrow up to right.
I feel like I am missing some simple step, but I just cant find it. My check engine light is also on and when I turn on my headlights it blinks, and idles worse. My S-AFC II show 62% throttle when I am at WOT with the car off, but then does not register at all when I start the car. I am confused and tired any help is greatly appreciated.

yes I went over the connections and I wired it correctly. The rpm's will rise untill like 1/3 throttle then it starts reading throttle. Yes I did the sensor check, but it was at 1.8 not 0-1. Is that normal?

no I think you misunderstood me. my in1 on the sensor is around 1.8 and nothing on the other 2, throttle goes to about 2.somthing is that normal. I disconnected the S-AFC and it starts and idles perfectly like before.

I used the wiring diagram from the apexi site. And yes I did the initialize procedure, but I will try it again, and double check wiring connections.

No, it's not wired correctly, you're reading the wiring diagram backwards - same thing I did. I wasn't paying attention to how they showed the connector and so I did it upside down.
The car was so rich and wouldn't idle unless I held it at 3k rpm. Just check the wiring, if it's not the wiring then you've skewed up something else where (make sure the grounds are right, etc)

Yes, it should unless you lean/richen it out on low-throttle setting.

Make sure the solders good on all connections, make sure the signal coming in/out isn't backwards. DONT use crimps because for some reason they don't work.
