WRONG 
|
CORRECT 
|
1
|
DO NOT place the ECU near direct heat sources and far
from the possibility of air exchange
|
Always place the ECU in a location
that can be easily reached by the outside air coming through the
radiator, preferably close
to the battery, on the outer side of the engine compartment
|
2
|
DO
NOT place the control unit with the connector upwards as the
condensation would not find a way out
|
Place the ECU vertically with the
connector downward, to facilitate the outflow of any condensate.
If it's not possible to use the position just suggested, opt for the horizontal position
|
3
|
DO
NOT place the Reducer higher
than the radiator, because any air present in the pipes would stop in
the Reducer preventing the circulation of the water, with the risk of
freezing and damaging the membranes
|
Place the Reducer below the top of the radiator,
so that any air present in the pipes can be purged normally
|
4
|
NEVER
place the Reducer in a way that the hose of the MAP engine Vacuum is too long
otherwise, in case of rapid acceleration, the reaction of the Reducer's
membrane will become slow, out of sync, with poor performance
|
Try to keep the TOTAL length of the
Vacuum hoses (Reducer pipe + Pressure Sensor pipe) always less than 60 cm!
Should this be impossible, consider the possibility of using a copper
pipe with just two small rubber ends
|
5
|
The
two pipes of the Reducer's Vacuum and of the Pressure Sensor must NOT
be connected at different
points,
as the measured pressure may be different, with the risk of possible
changing over to Petrol mode even when the Gas tank is still full
|
The depression for the Reducer and
for the Pressure Sensor has to be taken from the same point of the
manifold, by a T joint
|
6
|
DO
NOT place the Injectors tilted, with the coil downward,
because any residual in the Gas, especially if LPG, can stagnate,
hardening and blocking the movement of the shutter or restricting its
hike
|
Place the Injectors preferably upright
or, if absolutely necessary, tilted so that the residues of the Gas can
flow into the engine, without stagnate in the shutter head. Try to keep
the length of the pipes always less than 10 cm!
|
7
|
DO NOT use pipes of too much different lengths or
it will generate an asymmetrical injection which could cause instability
|
The best solution is to split the Injectors in 2
pairs.
Alternatively, a compromise solution consists in lengthening the two
central pipes, inverting them if necessary, but in the latter case the
electrical connectors (only for the Gas Injectors) must also be
reversed!
|
8
|
DO
NOT feed 2 groups of Injectors starting from the extremity,
because the last Injector would receive a
quantity of Gas by far lower than the first Injector, especially under
load
|
Always feed 2 groups
of Injectors from the
center, for a more uniform distribution of the Gas
|
9
|
DO NOT install the nozzles of the
Injectors too distant
from the Petrol Injectors, because the excessive distance not only
creates a delay in the Gas flow time, but it accentuates the Gas
suction phenomenon from a cylinder by the adjacent cylinder; and
sometimes anticipating the injection time electronically doesn't
completely solve this mechanical defect
|
The best solution is to not exceed
the maximum distance
of 5 cm.
If this is not possible, a compromise solution is to use a Copper or
Teflon pipe for bringing the injection point to the valves
|
10
|
An
old or dirty spark, which in Petrol mode does not give any problems,
may cause misfirings
only when running on Gas
|
The poor efficiency
of all components subject to wear is the most common cause of issues of
a Gas installation, sometimes not found in Petrol mode, like sparks and
coils
