I'll get some data logs tomorrow. I'll do one with the engine stone cold, then one when its lukewarm, and then when its full warm.
My general observations are that the engine switches to closed-loop fairly quickly after the car is started. It generally takes only two minutes before its running in closed-loop. When the car is lukewarm, there is a tendency when the car is idling for the afr to swing from ~13:1 to as high as 17.5:1, and the stalls occur when it swings super lean.
KC, I'd recommend first trying 3/4" ID. That's the largest you'll want to use with an Impreza RS fpr. If you install an adjustable fpr and go with a higher fuel pressure, then you can try larger diameter hoses as you increase the fuel pressure, but you'll have to be very careful about building in too much ignition advance.
