Default unusual knock issue - built motor

yeah, i just built this motor (http://forums.nasioc.com/forums/showthread.php?t=993446) and i;m using the same utec and ecu from before the build. also, the map is an 1820/fmic/650 tune from eons ago (as before, i used this prebuild). the engine is quite loud...mainly piston slap.

no, the utec does not like the noise. yes, the CEL flashes indicating knock AND my logs all read craziness. any thoughts? piston slap does not = knock, correct? if that's true, is the crazy slapping loudness invoking a false CEL or are my crazy logs showing me that my new build WILL NOT (or atleast doesn't want to) run on this map?
