I have done the idle learning procedure on my PFC twice now after resetting it both times. The PFC won't even stay running through the whole thing, and then dies whenever I put the AC on, and will barely stay running normally (idles around 500 rpm). The stock ECU idles just find and will idle up whenever the AC is on or there is an electrical load, just as it should.

My car is almost entirely stock. It has a downpipe, and aftermarket boost controller, and that is it.

Thanks.

what are your rev/idle rpm's set to in the Settings 1 tab?

750, 850, 950.

I have tried upping the base (no load) idle and it does nothing. The idle stays at the same point. I thought this might mean a bad idle control valve, but the stock ECU seems to raise the idle just fine.

You can try opening the air adjusting screw under the throttlebody elbow. It's a bit hard to say without having Datalogit logs to analyze.

You should join arghx's yahoo tuning group.
On it there is the most compressive collection of tuning documents.
One is all about adjusting the throttle body.
