The VSI ECM only translates the relevant signals coming from the engine management system necessary for MASTER /SLAVE strategy. This means that the original petrol management ECM controls the amount of LPG injected via the LPG injectors into the engine. The two systems integrate as master-slave system. VSI characterizes itself with a high level of integration into to the petrol management system. The VSI system was designed and developed in-house by Prins Autogassystemen B.V. This achieves a much higher level of performance emission and drivability. Sequential means that the LPG injectors will inject the LPG in the sequence equal to the injection sequence of the petrol injectors, This sequence in most applications is equal to the firing order of the ignition sequence of the engine, for example with a 4-cylinder engine this is normally Sequential injection means that the amount of injected fuel per cylinder the can be metered and timed individually. This second-generation gas injection system is based on a vapour LPG injection that is injected sequentially in the engine. Please fill in the warranty card completely and return it within 8 days after installation.Ĥ PAGE 4 076/ INTRODUCTION VSI stands for vapour sequential injection, it points directly to the most important properties of the system. Fitting and maintenance is only allowed by Prins Autogassystemen selected LPG engineers. Mount the VSI-system according to the local LPG regulations. After having completed the installation, check the whole system for gas leakage use a gas leak detection device. (This guarantees the maximum flow through the hose without pollution.) If holes have to be drilled (wear safety glases) in order to facilitate mounting the device frame, the reservoir frame, the LPG cut-off valve, etc., the drilled holes must always be treated with an anticorrosive, after the burrs have been removed ( especcialy when mounting a exterrior filler ).
Remove any internal burrs, after having shortened the LPG hose. Ensure maximum care is taken when connecting wiring. The wire loom is not model specific, therefore is it may be necessary to adjust the length of the wires. The text on the cable explains the function of the wire.
The cables in the loom are provided with numbers and text. Always fix the computer in the coolest place in the engine compartment. The watertight ECM housing is made from aluminium this material is chosen for its excellent heat dissipation qualities, necessary for cool the injector drivers. Solder and insulate all electrical connections. The power supply cable and the ground cable of the VSI system are always to be connected at the battery. When installing the cable harness, ensure that it does not run near any of the ignition components. Never disconnect the VSI computer connector, unless you have removed the 7,5 A fuse. In the unlikely event the VSI computer fails, it will automatically switch over to petrol.

The VSI computer has to be activated by means of the diagnosis software (refer to the last page). GENERAL INSTRUCTIONS Do not place the 7,5 A into the fuse holder before having completed the installation of the VSI system. Exhaust-emission tester - Gas leak detection device.
