Quite far but some of it is still guess work or unknown. The DCL data stuff's been hard to get my head around. TBH I haven't done much recently as I've got too much other stuff on and I think I might end up using a normally aspirated ecu ('93 Mondeo probably) for my supercharger project as I don't need a map sensor or wastegate control. Also I dislike the 'tacked on' approach Ford took with adding the extra code onto what's basically a normally aspirated ecu's code.
