Installation and adjustament manual13/26INSTALLATION- When routing the hose, avoid paths that require sharpbending which can deform the tube and reduce the flow.- Once the hose is connected, secure it with the clampsprovided4.4.5.3 Tube between distributor and injector jets(diameters: I.D. 4mm; O.D. 6mm)- The length must be the one indicated by the “vehiclefile.”- The tubes must all be of the same length.- After cutting the tubes, remove shavings and burrs fromthe 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 theclamps provided (Fig.4.7).dashboard.- Mount the switch in the dashboard after cutting arectangular hole of appropriate dimensions (about25x38mm) with the special cutting tool.- Set the switch externally to the dashboard by using thebracket provided.4.4.8 Installation of injector’s simulator- The “vehicle file” indicates if and which type ofsimulator must be utilized. To install, follow the specificinstructions enclosed with the product.4.4.9 Electrical connectionsPart of the electrical connection is achieved through pre-assembled harnesses and connectors. The electricalconnections must:- Follow the wiring diagram of the “vehicle file.”- Be kept away from heat sources such as exhaustmanifolds, radiator etc.- Be kept away from moving parts such as fans, belts,etc.- Be kept away from high tension wires such as sparkplug wires.- Follow the routing of the original vehicle wiring andsecure the LIS wiring by means of straps whennecessary. In this way the installation is protectedfrom accidental tearing during engine service.- Solder each connection and seal it with heat-shrinktubing.- To find the +12V power source for the LIS, see thewiring diagram of the “vehicle file.”- Connect the ground wires to a reliable ground.In the proportioner unit, the idle/low power stepper motoris marked in red; make sure that only the harness connectormarked 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 segmentmust be as specified in the “vehicle file.”- Utilize the connecting “Tee” provided; avoid routingsuch as to sharply bend the hose.- Once the hose is connected, secure it with the clampsprovided.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 lengthin order to pipe the possible discharge of the safety reliefvalve to the outside of the engine compartment. The outletof the piping must be in a ventilated area away from heatsources 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 thevehicle’s make and model, to which the ECU’s softwareis referred.- Position the ECU away from heat sources such asexhaust manifold, radiator, etc., and protect against waterinfiltration.- Mount the ECU on the vehicle’s body inside the enginecompartment in such a way as to allow easy access toconnect 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 ofthe following ways:- Mount the switch in a non-utilized cavity of theFig.4.7 |
