- press the push-button ACCEPT.
On the switch, it is therefore possible to see the
following changes:
Reserve
= LEVEL value when the LED of
1/4 switches off and the reserve
one switches on.
Reference 1/4 = LEVEL value when the LED of
2/4 switches off.
Reference 2/4 = LEVEL value when the LED of
3/4 switches off.
Reference 3/4 = LEVEL value when the LED of
4/4 switches off.

GAS PIPE FILLING TIME.
Usually, the gas control unit, to prevent the possible shut-off of the car during the switching from
one type of fuel to the other, enables the gas solenoid valves 5 seconds before performing the
switching: this allows a greater fi lling of the piping.
It is possible to disable this function. In this case, the gas solenoid valves are enabled only for
about 1 second.
WARNING
IT IS SUGGESTED NEVER TO DISCONNECT THE PETROL PUMP
8.5.4 MAP.
This menu allows performing a numerical display of the multiplication coeffi cients called K used by the
control unit in the calculation of the gas injection time.
The table shows on the vertical axis the petrol injection times, while on the horizontal axis there is the
number of engine revolutions. The red point shown on the map identifi es the revolutions references
and the petrol injection times with which the engine is working (with gas feeding the point is green).
By increasing the value of K, at same PETROL injection time, the gas injection time is strengthened,
while reducing the value of K, the contrary operation is performed obtaining a weaker mixture in the
system.
To modify the values of K, select one or more boxes of the map and press the key enter. A window
appears with the following modifi cation modes:
ABSOLUTE
- it allows bringing the map exactly back to the value corresponding to the one entered.
LINEAR
- It adds or deduces (in case a number with negative sign is entered) the entered value to/from
the one already present in the selected box(s).
PERCENTAGE
- It adds or deduces in percentage the entered value to/from the one already present
in the selected box(s).
