safc losing setup info help!
 

So i'm gonna keep my wiring woes short... The power wire you splice off the pcm wiring harness, is it constant power or acceossory power? I have had to re-wire most of this car and after re-wiring my pcm I found that my safc does not save my settings for sensor type, car type etc... I'm wondering if I can run a fused constant power wire to keep my settings or my safc is pooched... I have a feeling the safc is no good because if I wired it constant power it would not turn off... any suggestions ppl?

can anyone tell me on a s4 when that power wire that supplies voltage to the safc has power? Is it constant or ign switched on?
