the suction manifold in the maps:
introduce the maximum value of the
achievable manifold pressure. In
case of vacuum engines set 1000
while for LPG turbo ones set 1700.
By clicking ADVANCED key in
the injectors and other components
section, you can display the injector
characteristics (picture 5.2b). In
case of problems it is possible you
will have to read them to BRC
Technical Assistance service.
Finish and verify the introduced
values, then click on EXIT to continue.
The carried out modifications
have to be confirmed by clicking
YES when required.
5.3 LEVEL CALIBRATION
This section allows to calibrate
the tank level sensor. A correct calibration
permits to display on the
petrol/gas changeover switch the
information concerning the filling
up.
At the beginning the values
memorised in the ECU are displayed
but, if not correct, it is necessary
to calibrate the level sensor.
To carry out a correct calibration
the tank has to be empty in order to
get the level sensor signal clicking
empty tank acquisition; the registered
value appears in the cell near
the key (picture 5.3).
After the gas filling up click on
full tank acquisition and the
obtained value appears in the cell
near the key.
Clicking on LPG (or CNG) set
values you can introduce some
standard values which normally
correspond to a correct calibration
Fig. 5.2b - Setting up – installation and injectors calibration by clicking ADVANCED key
in the injectors section
Pic. 5.3 - Setting up – tank level calibration
of BRC resistive level sensor.
These values are:
For LPG
• Empty tank = 70mV
• Full tank = 1100mV
For CNG
• Empty tank = 70mV
• Full tank = 1050mV
You can set percentage discriminating
the passage among the different
levels and the consequent
38
indication change on the
changeover switch. Usually these
values are set in order to have a
balanced division of the levels.
Anyway, if you wish to increase or
decrease the persistence of one of
the levels, to better set the indication,
you need to manually modify
the values.
Clicking %->Electric the values
of the screen are displayed in mV
instead of as a percentage and vice
versa (picture 5.4).
Finish and verify the calibration,
