I'm reading about auto fill flash reduction in NK guy's EOS flash document. Do I have it in an XS+430EX? If so, how do I turn it off so I can control FEC myself? (can't find a cfn that does that).

Are you talking about the shift in Av / Tv/ P mode to underexpose ambient by ~1 stop above EV 13 when flash is enabled? This is in all Canon cameras and can be bypassed by shooting in M mode and selecting the exposure of ambient as you desire it.

Fill flash reduction is something else. That's a reduction of the flash power, when the flash is used in condition that are bright enough for the camera to decide that you must be using fill flash.
The reduction of ambient exposure mentioned above is just something the camera (or user, in M) has to do to avoid overexposing when you mix ambient and flash.
