I played around a little bit over the weekend with my K-30 and 360FGZ. What I found is that in P mode, if I follow these steps in order, starting with the camera off:

1) mount flash on camera
2) turn on camera
3) turn on flash

... then I would get reliable results with no FEC (and the flash in P-TTL). Bounce or direct -- in fact I think the bounce results were particularly good. In case anyone is wondering, I had the flash set around 75 deg (not quite straight up) for the bounce shots.

The design for P mode flash exposures seems to be:

1) Camera adjusts the shutter for slowest non-blur speed for the detected lens focal length
2) Camera adjusts aperture to capture the most ambient light available
Here's where it gets fuzzy:
3) Camera selects some combination of ISO and flash power for best exposure

(I think the programming tried to keep ISO in the 200 to 500 range regardless of ambient light level but I can't say that with certainty)

Does this correlated with others' experiences?
Have you tried with bounce flash and no ambient light? That´s what make my pics overexposured, unless you switch to LiveView.
