SWITCHING TO PETROL FOR LOW GAS TEMPERATURE

If the temperature of GAS falls below the threshold set, the ECU switches to the petrol mode and 
the corresponding diagnosis is activated (code S110). The ECU automatically back to gas mode 
when the gas temperature allows it

•  

ANTICIPATE INJECTION SEQUENCE.

This is a guided procedure allowing the automatic acquisition of the injection sequence, as well as 
the enabling of an advance phase shift of the gas injection; the entity of the phase shift depends 
also on the command “Number of main bearings” of the page F3 Sensors.   
This advance can increase the car operation above all in case of gas injectors far from the suction 
manifold.
This function is to be used only if really necessary, since it disables the characteristic of GRA-
DUAL PETROL-GAS switching performing such switching instantaneously.

•  

IDLE OPERATION.

GAS

 - By enabling this function, the car at minimum always works by GAS feeding (default and 

suggested option).

CHANGE  BACK  TO  PETROL 

-  During  the  return  to  minimum  the  car  switches  for  some 

seconds  to  petrol  and  then  returns  to  gas  feeding,  avoiding  in  some  cases  the  shut-
off  during  this  phase.  It  is  suggested  to  use  this  function  only  if  necessary.  The  va-
lue  “Revolutions  for  identifi cations  of  the  minimum  (Giri  per  identifi cazione  del  mi-
nimo)” determines the number of revolutions under which this procedure is enabled. 

PETROL 

- The operation at minimum, under the set value of revolutions, is always by petrol fe-

eding. The restoration of gas operation occurs when the revolutions exceed the set value. This 
function has to be used only when the operation at minimum by gas feeding is impossible, insta-
ble and results in frequent shut-offs.
The indication that the system is working by petrol feeding does not occur by means of indication 
on the switch that remains on gas feeding, but by the reading on the computer of the gas injection 
time that becomes null.  
In fact, in this phase the switch keeps signaling the gas operation and the gas solenoid valves 
remain enabled.  
In case of presence of the advance converter, which remains fed in this phase, it is necessary to 
pay attention that introduced advance does not disturb the operation of the system.

• 

OPERATION AT HIGH REVOLUTIONS

GAS 

- The car works on gas. If the gas time limit is reached (gas exceeds the time of cyvle), a 

small correspondent quantity of petrol is added at the same time. The signalling on the switch 
remain on gas operation.
Removing the cue from the check box you disable this function and if the gas time limit is reached 
the car automatically changes back to petrol with consequent signalling on the switch.

PETROL 

- The car temporarily runs on petrol mode at high rpm and high engine loads. 

You can set the number of rpm and the injection time over which car will run in petrol: both condi-
tions must be met to run on petrol mode.
In this case, the switch is on gas mode

PETROL CONTRIBUTION 

 – You can make a small contribution of petrol during gas mode. You 

can set the injection time beyond which you can get the petrol contribution and set the millisecon-
ds of contribution.
This contribution is then subtracted from the petrol injection time before calculating the correspon-
ding gas injection time
