NOTE:
pre-purge starts as soon as the damper reaches pre-purge
position and - if you use a VSM - the last but one point of the
fuel/air ratio curve is passed.
The points are approached from above by using the over-
shoot-function. If you use the over- shoot-function in opera-
tion, you must program all points from above. Only if you do
so, the required position will match the actual position.
The channels' position in the last but one curve point must
be lower than at the last curve point.
