INSTALLATION
-
When routing the hose, avoid paths that require sharp
bending which can deform the tube and reduce the flow.
-
Once the hose is connected, secure it with the clamps
provided
4.4.5.3 Tube between distributor and injector jets
(diameters: I.D. 4mm; O.D. 6mm)
-
The length must be the one indicated by the “vehicle
file.”
-
The tubes must all be of the same length.
-
After cutting the tubes, remove shavings and burrs from
the ends and make sure that the inside is clean.
-
Route the tubing in such a way as to avoid sharp bends.
-
Once the tubes are connected, secure them with the
clamps provided (Fig.4.7).
dashboard.
-
Mount the switch in the dashboard after cutting a
rectangular hole of appropriate dimensions (about
25x38mm) with the special cutting tool.
-
Set the switch externally to the dashboard by using the
bracket provided.
4.4.8 Installation of injector’s simulator
-
The “vehicle file” indicates if and which type of
simulator must be utilized. To install, follow the specific
instructions enclosed with the product.
4.4.9 Electrical connections
Part of the electrical connection is achieved through pre-
assembled harnesses and connectors. The electrical
connections must:
- Follow the wiring diagram of the “vehicle file.”
- Be kept away from heat sources such as exhaust
manifolds, radiator etc.
- Be kept away from moving parts such as fans, belts,
etc.
- Be kept away from high tension wires such as spark
plug wires.
- Follow the routing of the original vehicle wiring and
secure the LIS wiring by means of straps when
necessary. In this way the installation is protected
from accidental tearing during engine service.
- Solder each connection and seal it with heat-shrink
tubing.
- To find the +12V power source for the LIS, see the
wiring diagram of the “vehicle file.”
- Connect the ground wires to a reliable ground.
In the proportioner unit, the idle/low power stepper motor
is marked in red; make sure that only the harness connector
marked in the same way is connected to it.
4.4.5.4 MAP hose (diameters: I.D. 5mm; O.D.
10.5mm)
-
The routing of the hose and the length of each segment
must be as specified in the “vehicle file.”
-
Utilize the connecting “Tee” provided; avoid routing
such as to sharply bend the hose.
-
Once the hose is connected, secure it with the clamps
provided.
4.4.5.5 Venting tube from safety relief valve
(diameters: I.D. 5mm; O.D. 10.5mm)
Connect to the safety relief valve an adequate tube length
in order to pipe the possible discharge of the safety relief
valve to the outside of the engine compartment. The outlet
of the piping must be in a ventilated area away from heat
sources and electrical devices.
Also, the outlet of the piping must point towards the road,
and be free from impingement.
4.4.6
Installation of the LIS ECU
-
Fill in the label on the ECU unit. The label carries the
vehicle’s make and model, to which the ECU’s software
is referred.
-
Position the ECU away from heat sources such as
exhaust manifold, radiator, etc., and protect against water
infiltration.
-
Mount the ECU on the vehicle’s body inside the engine
compartment in such a way as to allow easy access to
connect and disconnect the harness’ connector,
following the instructions in the “vehicle file”.
4.4.7
Installation of the switch
-
Install the switch on the vehicle’s dashboard in one of
the following ways:
-
Mount the switch in a non-utilized cavity of the
