DATA SETTING
8
Landi Renzo S.p.A.
NUMBER OF CYLINDERS (IGNITION)
(fig. 12)
4, 5, 6, 8 CYLINDERS: Set the number of cylinders only when the ignition system is composed of one coil per
cylinder, or if you connect up with the rev counter.
COILPACK: for 4-cylinder engines with 2 coils or if you connect to the coil negative of a twin-coil.
SINGLE-COIL: when you connect to the negative of a single coil that supplies all the cylinders through the
distributor.
RPM SIGNAL TYPE
The intensity of the signal indicates the engine speed (fig. 13).
STANDARD: This is used for most engines when there is an engine speed signal greater than 5V.
WEAK SIGNAL: This is used when the engine speed signal is less than 5V (eg. if the changeover from petrol to
gas does not occur).
TYPE OF CHANGE PETROL-GAS
(fig. 14)
DECELERATION: The fuel changeover is made, after acceleration, on releasing the throttle.
ACCELERATION: The changeover is made during acceleration.
OPTION2: The engine directly starts on gas (enabled oany in certain ECUs).
RPM SELECTION FOR CHANGE OVER
Indicates what speed the fuel changeover from petrol to gas must be made at (fig. 15).
OVERLAP TIME
This is the delay time, during the phase of passing from petrol to gas, which passes from the time when the gas
solenoid valve is opened to the time when the injectors are closed; this permits the gas to fill the intake pipes (fig.
16).
TYPE OF TPS
(fig. 17)
This is the “page” that makes it possible to set the type of throttle sensor installed on the vehicle.
Linear TPS 0-5V: the voltage of 0V indicates throttle closed, 5V the throttle is fully open.
Linear TPS 5-0V: the voltage of 5V indicates throttle closed, 0V the throttle is fully open.
SWITCH 0-12V: the voltage of 0V indicates throttle closed, 12V the throttle is fully open.
SWITCH 12-0V: the voltage of 12V indicates throttle closed, 0V the throttle is fully open.
