MAP correction map (autoadaptation map)
Autoadaptation systems available in STAG 400 DPI controllers are provided with dedicated maps
of correction with rpm and load (MAP negative pressure) axes to make the corrections more
natural and precise. The map view can be accessed through the “MAP correction Bx” tab. If
autoadaptation is inactive, the map can be used for additional, manual corrections of gas fuel
dosing.

MAP correction map
If autoadaptation is active but it is not desired in certain ranges of engine operation, it is possible
to deactivate such ranges in the autoadaptation process. Select an area of the map with a mouse
and click the right button after selection. A context menu with “Autoadaptation lock” and
“Autoadaptation unlock” commands is displayed. Locked areas are marked with grey correction
values.
Controllers offer two MAP correction maps, one for each bank. The maps can be switched only
with B1/B2 buttons under the map clearing button .
