lower (Injection time [ms]) axes are subordinated to this map. The map consists of blue points.
After collection of data the controller draws the map with a continuous line. The same procedure
concerns the so-called LPG map i.e. the map of gasoline injection times (with LPG), which is of
green colour.
When the controller collects two maps i.e. gasoline and LPG maps, it is possible to enter the
bookmark Deviation, where the red line shows difference between gasoline and LPG. Depicted
map window (Fig. 9) shows also the square blue marker, which position changes depending on the
collector pressure and gasoline injection times. It is very useful during collection of the map
because it shows at which load and injection time works the engine. At the map there are also the
buttons “Delete” used for erasing of gasoline and LPG maps. Nearby the buttons is situated the
selection field “Lock”, which is designed for locking of the gasoline map after its collection i.e. the
controller having collected the gasoline map (when the map is drawn with a continuous line) will
not modify it.
2.9. Assistant
Using the option Assistant it is possible to set all options required for setting of the controller,
including the auto-calibration.
2.10. Controller settings
The window Controller settings allows to change the sensor type for:
• LPG pressure (default PS-01)
• Collector pressure (default PS-01)
• Pressure regulator temperature (default CT-04-2K)
• LPG temperature (default CT-02-2K)
Also available is here the option:
• Controlled gasoline injection + - gasoline injectors controlled with positive pulses (in some
vehicles injectors are controlled with positive pulses and not – as for most cases – with
negative ones).
2.11. Controller update
To update the controller it is necessary to connect the controller with a diagnostic program
and switch off the engine. Select from the main menu the option “Controller update”. On the screen
appears the window Controller update. The frame “Controller parameters” displays information
about the software version. Press the button “Load update” and select the update file adequate to the
PCB (board) controller version. The PCB controller version is defined by first two digits of the
version code i.e. the controller with the version code 1.6.18 has:
• 1.6 – board (PCB) controller version
• 18 – controller software version
For above example the update file should be marked 1.6.x, where x means version of updated
software.
Having loaded the update file press „Update”. When the update progress bar reaches 100 % the
controller will disconnect for a moment and then should connect anew. In the bottom of the screen
should be visible the new number of controller software version compatible with the loaded update
file.
If in the course of update occurs an error and there is no possibility of connection with the
controller, then it is necessary to (for the 19 firmware version and older):
Close the diagnostic program
• Switch the ignition switch off
• Disconnect the RS-232 interface from the PC
• Start the diagnostic program (the program sends the message: no LPG controller)
• Connect the interface to the PC
• Remove the main fuse an put it back (the LED at the switchboard should come on)
• Before the LED comes off press the button at the switchboard (the led should come off)
• Enter the options of controller update, select the update file and press “Update”
