TYPE OF IGNITION
This parameter is used by the control unit to calculate correctly the engine standard operation,
which varies according to the type of ignition on which the BLACK wire is connected. Set:
SINGLE COIL
for cars with a coil every cylinder, if the BLACK wire is connected to
the negative pole of one of the coils;
DOUBLE COIL
for cars with a coil every 2 spark plugs, if the BLACK wire is connec-
ted to the negative pole of one of the coils;
REVOLUTION COUNTER
for cars with a coil and mechanical distributor, if the BLACK wire is
connected to the negative pole of this coil, or on all the cars where
the BLACK wire is connected to the wire signal revolution counter.
REVOLUTION COUNTER 2
not used
•
NUMBER OF CYLINDERS
This parameter is used to indicate to the control unit how many cylinders has the car and, therefo-
re, how many gas injectors shall it control; set 3 CYLINDERS or 4 CYLINDERS in function of the
number of cylinders of the car.

RESET
By clicking on the push-button of program reset cancel all settings of the control unit and loads
the default confi guration.
8.5.2 SWITCHING.
This window allows selecting the switching mode from petrol to gas and vice versa.
•
SWITCHING
During acceleration
The switching from PETROL to GAS occurs during acceleration when the car exceeds the num-
ber of revolutions set under “REV THRESHOLD FOR SWITCHING”.
During deceleration
The switching from PETROL to GAS in this case can occur following any of these two conditions:
- When the number of engine revolutions exceeds the reference set under “REV THRESHOLD
FOR SWITCHING” and then falls under such reference.
- When a Cut-Off condition occurs with the number of engine revolutions higher than the referen-
ce set under “REVOLUTION THRESHOLD FOR THE SWITCHING”
•
REV THRESHOLD FOR SWITCHING.
This identifi es the engine revolutions at which one wishes to perform the petrol-gas switching.
•
SWITCHING DELAY WITH WARM ENGINE.
This indicates the minimum time from the start of the engine for the switching from PETROL to
GAS.
We suggest setting a time not shorter than 25 seconds to assure the correct operation of the sy-
stem.
