The Lambda feeler supplies information on the amount of oxygen present in the exhaust
gas to consequently adjust carburetion. In the presence of a lot of oxygen we would have
a basically POOR carburetion (little GAS), on the contrary in the presence of little oxygen
we would have a RICH carburetion (a lot of GAS). In order to identify the wire of a lambda
feeler, we suggest using a multimeter, better if digital. Set the instrument to measure
continuous voltage, set a rod to earth (battery) and with the other rod check which wire has
a variable voltage. It is important that the vehicle is warm before measuring is done.

O2 sensor type
O2 simulation
Open loop starting time
The engine rpm signal can be taken directly from the coil negative or from the revolution
counter signal. It is, however, important that it is connected to the "VOILA PLUS"
panel box in order to ensure correct operation.
COMPUTER PROGRAMMED FUNCTIONS
Ignition type
RPM signal time
A relay has been put inside the "VOILA PLUS" (only for those vehicles whose panel box
performs no diagnoses on injection) and its function is that of injector detaching. When
switching on from PETROL to GAS, there is a time foreseen (called overlapping) in
which injector functioning is not immediately locked. This in order to allow the GAS to exit
from the reducer and reach induction, thus avoiding feed gaps and consequently
backfiring. In this way, during switching the two fuels (PETROL and GAS) will overlap for
a time that can be adjusted.
