• When the update progress bar reaches 100 % the controller should connect automatically to
the diagnostic program.
(For the 20 firmware version and newer):
Diagnostic program will detect error at the controller update and after connecting with controller
will open controller update window. You should repeat update process once again.
3. Programming of the VECTOR controller
Programming of the VECTOR controller can be performed with help of two methods:
• Programming with help of gasoline and LPG maps. See 3.1 to 3.4
• Manual setting of the controller. See 3.5
Programming with help of LPG and gasoline maps can be divided into following stages:
• Auto-calibration of the VECTOR controller
• Collection of the map of gasoline injection times with gasoline (gasoline map)
• Collection of the map of gasoline injection times with LPG (LPG map)
• Check if both maps agree; verification of deviations
3.1. Auto-calibration
Prior to starting the auto-calibration start the engine and wait until the lambda probe starts to
work. During auto-calibration the engine should work at idle run; do not increase rpm, switch off
air-conditioning and lights, do not turn the steering wheel, because this may cause erroneous action
of the auto-calibration. During auto-calibration watch carefully gasoline and LPG injection times. If
LPG injection times are shorter than gasoline injection times, the injector nozzles may be too great
and should be replaced with smaller ones. When the auto-calibration is finished on the multiplier
map should appear 2 extreme points and 4 points in the middle of the map. The second left point is
the point of engine operation at idle run i.e. the point of operation during auto-calibration. The
multiplier’s value for this point should be between 1.2 and 1.6; if the value is greater than 1.6 then
longer times of gasoline injection i.e. greater load and high rpm may cause overlapping of injection
times i.e. during the LPG injection comes the next one (loop of injection times). In such case the
controller sends the error message „injection time too long”. However, in such case it is necessary
to check operation of the lambda probe; if it is in the “rich” mode and the vehicle drives
without problems, the error can be ignored.
3.2. Collection of the gasoline injection map with gasoline (gasoline map)
Having made the auto-calibration switch over the vehicle to gasoline and drive ca. 4 km to
collect the gasoline map. During collection of the map try to drive without changing gears e.g. at the
4th gear and in such way so that the lambda probe “works” i.e. changes its mode from weak to rich.
During collection of the map should appear blue points. To collect the map quicker select vehicle
load in such way so that collect points in places, which are empty until now. Collection of maps is
performed without participation of the diagnostic program, thus can be done with
disconnected computer. However, while performing this action with connected computer and
diagnostic program we can do it much quicker and we see accurately, what happens to the vehicle.
When the controller recognises that the number of collected points is sufficient, the map will be
drawn with a continuous line. In this very moment collection of the gasoline map is finished.
3.3. Collection of the gasoline injection map with LPG (LPG map)
Having collected the gasoline map we switch the vehicle to LPG and start to collect the LPG
map i the same way as for the gasoline map. The LPG should be collected in the same road
conditions and with similar loads as for the gasoline map. The LPG map is drawn with green points.
Having collected sufficient number of points the map will be drawn with a continuous line. If the
controller is properly set (multiplier characteristic selected properly) the gasoline and the LPG maps
should agree. If the maps do not agree, the multiplier characteristic should be corrected in the
points, where the maps do not agree (the lower axis of co-ordinates for injection times). During
collection of the LPG map, if the computer is connected and the diagnostic program started, we can
