how can you map for all engine speed load conditions, with just one screw.
and by that theory, if you have the 'correct' fuelling at idle, you will have the correct fuelling over the whole rev range
presumably you set the screw for your base idle,then adjust the values within the map for all conditions,i'm sure Stu or somebody will explain it better,but that pot is normally fitted with a tamper proof plug,presumably ford didn't want people messing with it
