was performed properly, all mechanical issues have been eliminated and
injection times variations for given injectors are still present when using LPG. Do
not ever use injection strip-collector pipes of different lengths and then the
injectors’ calibration to accommodate this difference!!! Also never use this
option when the system is not in a perfect working condition or when some of its
elements have worn out.
Using this option in a manner not consistent with the above instructions may
result in damage to the car!!!
Injection sequence
– Here you can freely configure the injection sequence (which
petrol injector is to control respective gas injector). In 4-
cylinder controllers, the “180°”
button is used for quick switching of the injection sequence. This results in switching of
1:1,2:2,3:3,4:4 configuration to 1:3,2:1,3:4,4:2.
Configuration
– the new window
(Fig. 20) allows automatic checking and automatic
change of the gas injection sequence. Each time the button "@xx" button is pressed,
the injection sequence timing will be advanced by a given angle of "
xx
" with respect to
the current setting. This operation accounts for the real order of petrol injectors and
configuration of cylinder banks. If the "@
xx
" button is inactive, it means that the
controller did not detect the order of petrol injectors or the engine is off, or, it is a
sequential injection engine.
Cycle counter
– a series of counters to count the operating cycles of individual gas
injectors. These values are saved in the nonvolatile memory of the controller, but they
are not saved in the "
set
" file with settings. The counters should be reset after injector
replacement. They are used for information purposes only.
Reducer temperature sensor
– pressure regulator temperature sensor type selection.
Gas temp. sensor
–
gas temperature sensor type selection.
Extra-injection off threshold
– petrol injection pulses shorter than the set value will be
ignored by the controller (gas injection pulses will not be generated for them).
Intelligent extra-injection handling
– checking the option will result in leaning of the
post-injection pulses. It should be used for extra-injection pulses that are too long to omit
them with the option of “Extra-injection switch-off threshold
”
.
For the option to perform
correctly, the injection pulses must not be the source of RPM signal.
In some Mazda cars, injection strategy varies from time to time to resemble semi-
sequential injection, which may cause the effect of “jerking”. It is recommended to
activate the “Intelligent extra-injection handling” for such cars.
Parameters in the OBD group
– settings of the connection between the controller with the onboard
diagnostic interface (available in STAG-4 QBOX/NEXT PLUS/ STAG-300 QMAX PLUS controller):
Configuration
–
selecting the “OBD reader” option results in an attempt to connect to the
onboard diagnostic interface after each key switching, if the controller operates in Auto
mode.
Interface type
–
Indicates OBD2/EOBD communication type available in the vehicle. The
default AUTO mode enables scanning and automatic selection of proper OBD interface. If,
despite of AUTO mode selected, no OBD communication can be established, an
appropriate interface type shall be selected individually.
The
Advanced settings
group offers the following options:
Emergency starts
– check to restrict the number of permitted emergency start-ups on
LPG and enter that limit into the “Allowed” textbox. The number of the start-ups already
done in the past is displayed in the “Performed” field. You can reset that counter using the
“Clear” button. Once the pre-set limit is exceeded you will not be able to start the engine
on LPG (in emergency mode).
