AC STAG-4 QBOX BASIC User Manual page 40

The multiplier map is displayed in orange. The left axis of the co-ordinate system (Multiplier) and the
lower axis (Injection time [ms]) relate to the multiplier map. The multiplier map is used to set the
multiplier for a given petrol injection time. The yellow points visible at the map are used to set the
multiplier. To move a given point, select it by clicking on it. The value of a selected point is displayed at
the lower right corner of the map.
To move the points on the map, use the following keys:
 ← - left arrow moves the point to the left (change of the injection time for a given
point)
 → - right arrow moves the point to the right (change of the injection time for a given
point)
 ↓ - down arrow decreases the multiplier for given injection times
 ↑ - up arrow increases the multiplier for given injection times
 „Insert" (when a point is active) or right mouse button– add a new point
 „Delete" – delete a selected point on the map
 „Page Up" – Rising a selected point by 10 units, or the entire map, if no points are
selected
„Page Down" – lowering a selected point by 10 units, or the entire map, if no points

are selected
 „Ctrl" + ← , or „Ctrl" + → change the active point (move to the next one)
When the „Shift" key is pressed in, the map movement speed is multiplied by 10 (fast movement).
When no point is selected, the ↑ ↓ arrows move the entire map. Apart from the multiplier map, there
are two other maps in the window. The blue map represents the petrol injection times (with petrol).
The right axis Collector pressure [Bar] and the lower axis Injection Time [ms] relate to this map. The
map consists of blue points. After collecting the data, the controller turns these points into a
continuous line. The same applies to the so-called LPG map, i.e. the map of petrol injection times (with
LPG) which is green.
After the controller collects both maps, i.e. the petrol and LPG maps, the Deflection tab becomes
active. Deflection appears as a red line after pressing button
The map window in Fig.32 shows also cursor, which position changes vertically depending on the
manifold negative pressure and horizontally depending on petrol injection times It is very useful during
map collection as it shows the load and injection times of the engine. After pressing button
"autoselection" became active, which means, that the multiplier points will be selected automatically so
that the point next to the cursor becomes active.
Maps can be deleted with buttons
During the drive, pressing the SPACE key select the point closest to the current
cursor position.
In order to make injection time map acquiring easier, on the left side of the multiplier window
suggested engine load areas are presented as vertical lines. The lines represent the areas of injection
time maps, which have not been recorded yet. The blue line represents the petrol injection time map
and the green one represents the gas map. If a given area of the map is acquired, the line section
associated with this sector disappears.
