4d mapping allows an additional input to be used as a parameter on either fuel/ignition maps, usually you use throttle position as the 4th, as this allows you to setup wide open throttle vs cruise/mid throttle applications without having to use an over-all compensation map.
i would be supprised if link maintained 440 zones in 4D mapping for both tables, but then again- they have put a lot of work into this model from the last one!
