Let me start off by saying I've done my fair share of searching this topic, but most of the stuff I see is conflicting anyway. I am curious about the IN/OUT settings for the MAF. My setup is stock S13 SR MAF, and #63 ECU. All have I really seen people saying is that for these criteria 6 in/6 out is the way to go. From my personal experience, my car runs perfect at 5 in/5 out. When i switched it to 6/6 the car suddenly leaned out at WOT around 6k and up. (have innovated wideband, a/f went from 11.8-12:1 to 14:5 suddenly). Does anyone have a definite answer as far as the settings go. Only reason I am curious now is because I am soon to do a Z32 MAFS

5 in 5 out is for KA MAF with KA ecu
6 in 6 out is for SR MAF with SR ecu
2 in 6 out is for Z32 MAF with SR ecu
2 in 5 out is for z32 maf with KA ecu

so u get the drill

another question, which turbo and boost level u are running?
stock SR MAF can be max out around 10-12psig, when its maxed out, anything more than 5v output from the maf will be un-registed air - lean

S14 T28 at 10 -12psi. I think I was only running 10psi at the time. What you said matches all the other info I just thought it was really weird that at 5/5 the car maintains perfect a/f ratio to redline, i've ran the T28 @ 12 psi before I installed the SAFC and never had any leaning out issues, a/f has always stayed fine. So when I switched to 6/6 and started having problems that seemed wrong to me
