Programmer tester Mod. V05 3
FEATURES
The Programmer Tester Mod. V05 is used to program and diagnose the LCS-A/1 V05 system.
It display parameters that characterize the operation of the entire system such as the lambda value (whether on
gas or petrol), the position of the linear actuator with the stepper motor and its default, the engine speed, and TPS
signal.
The Programmer Tester Mod. V05 is supplied directly by the cable linking it with the LCS-A/1 V05 central unit.

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.

MONOBOSCH: composedof 2sensors thatwork inparallel; it is to be found onMONO BOSCHinjection systems.
TPS ADAPTER: If the engine has no TPS the control unit will emulate the position of the TPS on the basis of the
engine speed.
INDICATOR SENSOR TYPE
(fig. 18)
LANDI RENZO: select this parameter for all LANDI RENZO sensors, both LPG and CNG.
AEB: if an AEB-type LPG sensor is used.
O-90W: for LPG indicator sensors that have an internal resistor of 0-90Ω.
LAMBDA SENSOR TYPE
(0-1V, 0-5V A, 0-5V B, 5-0V A, 5-0V B, 0.8-1.6V)
Tells the central unit what type of lambda sensor is mounted on the vehicle (fig. 19).

If the voltage varies between 0-1V or 0.8-1.6V, set the respective values.
Ifthevoltage varies ina range between0Vand 5Vitis necessarytomake anothermeasurementin order toidentify
whether it is type A or B.
To measure the voltage on the lambda sensor wire, you need to cut the sensor wire and measure the voltage on
the wire reaching the vehicle’s original control unit with the panel switched on.
The sensor is type A if there is a voltage of 5V on this wire.
The sensor is type B if there is a voltage of 0V on this wire.
0-5V A, 5-0VA: The type A sensor indicates a lambda sensor that keeps the wire at a voltage of 5V when this
receives no signal.
0-5V B, 5-0V B: The type B sensor indicates a lambda sensor that keeps the wire at a voltage of 0V when this
receives no signal.
LAMBDA SENSOR READING DELAY
Thisisthetimethatpassesfromwhenthesystemcomesintooperationandstartsreadingthelambdasensorsignal
(fig. 20).
This time allows the lambda sensor to warm up and to prevent the central unit from wrongly interpreting the signal
transmitted by the sensor.
The recommended method of identifying this time consists of starting the engine on petrol and measuring the time
the lambda sensor takes to transmit a signal with voltage within the working range.
Add 2 to 3 seconds to the measured time.

SIMULATION TYPE
(fig. 21)
SQUARE WAVE: supplies the vehicle’s computer, when running on gas, with a similar signal to the one received
from the lambda sensor when running on petrol.
The square wave, set in the factory, is suitable for most vehicles on the market.
Not all computers interpret the signal in the same way. Therefore, it is possible for the same signal to work well on
one car and not so well on another.
Ifthesimulatedsignalisnotcompatible,therecouldbeirregularoperationonpetrol,andthecheck-engineindicator
light might come on.
To solve this trouble the possibility has been provided of setting an appropriate signal indicated from time to time
by the
LANDI RENZO technical service.
DISCONNECTED: supplies the car computer with a disconnected lambda sensor signal.
Some computers on receiving the disconnected lambda sensor will ignore it, leaving the carburation on petrol
unaltered and engine check light switched off. This type of emulation generally works on cars of old design.
GROUND: supplies the car computer with information of a constantly lean mixture, it is used on MONO-BOSCH
systems.
SQUARE WAVE SIMULATION
Byselectingthesquarewavetypeofemulationitispossibletosettheparametersindicatedbelow(fig.23);change
these parameters only by following the instructions of the LANDI RENZO technical service.
HIGH TIME : the time of the signal emulating a rich mixture (fig. 22).
LOW TIME : the time of the signal emulating a lean mixture (fig. 24).
DISCONNECTED SENSOR TIME : the time passing between one set of pulses and the next (fig. 25).
NUMBER OF WAVES AFTER DISCONNECTION :the numberof wavesthat willbe sentto thepetrol computer
