control unit for the LPG system; it uses
the incoming signals from the petrol in-
jection control unit and converts them in-
to signals for the injection of the LPG.
The control unit for the injectors has the
same strategy as the petrol control unit
(phased, sequential, multipoint).

It should be remembered that when using
a fuel such as LPG the range is very vari-
able because, as well as driving and car
maintenance conditions, it also depends
on the different composition of the gas
which can vary not only seasonally but al-
so from supplier to supplier. LPG is, in ef-
fect, a composition of gas (butane and
propane) mixed in a way that may not be
standardized.
