witam wszystkich, chcialem wam zwrocic uwage na jeden detal, mianowicie reduktor prinsa jest doskonalym reduktorem pod jednym warunkiem, a warunek ten jest banalnie prosty. Nie moze on byc montowany poziomo, musi byc w pionie tzn, wezw wodne na dole, waz gazowy u gory. Poprawia to odpornosc tego reduktora na zanieczyszczenia o okolo 60%, czyli dosc mocno wydluza zywotnosc membran.zalaczam w pdf instrukcje prinsa sa w niej mozliwe montowania tegoz reduktora, z mojego doswiadczenia wynika ze reduktory zamontowane poziomo "wysiadaja" o ponad polowe szybciej jak te zamontowane w pionie. pracujem z tymi instalacjami na codzien i prawde mowiac wymiana membran nie nastepuje szybciej jak co 3 lata.

Introduction
VSI stands for “vapour sequential injection”, it points directly to the most important properties of the system.
This second-generation gas injection system is based on a vapour LPG injection that is injected
sequentially in the engine. 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 1-3-4-2. Sequential injection means that the amount of
injected fuel per cylinder the can be metered and timed individually.
This achieves a much higher level of performance emission and drivability. The VSI system was designed
and developed in-house by Prins Autogassystemen B.V.
VSI characterizes itself with a high level of integration into to the petrol management system. The two
systems integrate as “master-slave” system.
This means that the original petrol management ECM controls the amount of LPG injected via the LPG
injectors into the engine. The VSI ECM only translates the relevant signals coming from the engine
management system necessary for MASTER /SLAVE strategy.
Following this strategy the petrol management system is the “MASTER” and the VSI ECM the “SLAVE”.
The advantage of this strategy: while driving on LPG the lambda control and OBD functions keep within the
OE parameters, functioning correctly and controlled by the petrol management system. So when operating
on LPG it is not necessary to generate simulated signals.
There is one exception made for the petrol injector signals, while driving on LPG the petrol injector’s are
switched off to discontinue the petrol supply. To maintain the injection control signals it is necessary to
simulate the petrol injectors to ensure the original ECM does not detect a fault code. Secondly when
operating on LPG it is necesarry to maintain a petrol injector control signal to measure the required fuel
demand.
The second generation injection system VSI has the ability to inject sequentially making it quicker and
more accurate, large benefits can be gained in engine and emission performance.

Brands: Mainly brands who are connected with Ford technologies like:
* Ford models from 2003/2004
* Jaguar models from 2003/2004
* Some Volvo models from 2003
Connections and Set-up
Connect the PPS module according the shown schematic. Measure the voltage, on petrol, for the blue wire
(pressure sensor signal wire) when the engine is idling. Or read the actual petrol pressure when you have
the disposal of a scan tool which can read the actual petrol system pressure.
Next we have to setup the same Voltage (pressure) when running on LPG via de pot meter. The pot meter
is accessible when you remove the small protection cover of the module.

DSI connection:
Connect the interface wiring according to drawing, all blue and black wires are exchangeable since they
are internally connected.
The DSI makes it possible to connect two level sensors to one lpg switch.
The DSI will always show the highest lpg level on the switch.

Maintenance instructions
MAINTENANCE
Compared to driving on petrol, the maintenance of your car is more important if you drive on LPG. Small problems
or malfunctioning of the engine may be acceptable when driving on petrol, but may be irritating on LPG, as the
engine is more sensible on LPG. For trouble-free driving on LPG, you have to follow these maintenance
instructions.
-The general maintenance of the car related to spark plugs, wires, ignition, valves etc. has to be carried
out according to the instructions of the manufacturer.
-There must be evidence of the maintenance work (by means of a completely filled out service booklet)
according to the importer's instructions.
- Maintenance has to be carried out by an authorised dealer appointed by the importer.
- Adjustments and repairs to your Prins LPG system should only be carried out by an authorised Prins
dealer.
General
*
Because of driving on LPG you need to pay extra attention to:
valve adjustment
spark plugs, ignition wires and, if necessary, distributor cap and rotor
idle control, checking the function and for contamination
idle speed
functioning on petrol, with special attention to O2 sensor
cleaning the one-way valve of the negative crankcase ventilation system
reading fault codes
*
The filter unit must be replaced (together with the filter for the lock-off valve) after 25.000 kilometres
after the first installation. Afterwards the replacement period will be at every 75.000 kilometres or
2 years as a maximum.In case of contamination, check if this contamination persists in evaporator
and/or after filter unit and injector rail.
*
Check hose connections on reliability, for kinks and rubbing.
*
Check electrical connections.
*
Check electric connections ( especially battery connections )
*
Check the fixing of components.
*
Check for LPG leakage at the tank, the LPG fuel lock, converter, filter unit and injector rail.
*
Check for petrol leakage of petrol injector, if VSI couplings are mounted underneath the petrol injectors.
*
Check for suction of infiltrated air.
*
Check the emission control with Prins diagnostic equipment and exhaust-emission tester.

Checklist after installation
1.
Connect the serial interface wire and run the VSI diagnosis program.
Install the VSI main fuse, and program the switch.
Turn the ignition key in the accessory position.
When working on the car, beware of moving and rotating parts in the engine compartment.
2.
When commissioning the LPG system, you must activate the VSI computer with the diagnosis
software. When the VSI computer has not been activated, it will keep generating error code 160. To
activate the VSI computer, select function F11 (activate ECM).
3.
Check whether the program in the VSI computer matches with the car ( dedicated engine set ):
Refer with F2 to the box number and car description in the diagnosis software and compare these
with the set number.
4.
The system will switch over to LPG as soon as the temperature of the coolant (T-ect)
becomes higher than the parameter T-min set and when the TSO-cold time is expired.
5.
Check all components and connections for any gas leakage ( use a LPG leak detector device ) or a
fluid detection like soap. Caution for moving and rotating parts in the engine compartment !
6.
Let the engine run warm on petrol & gt; 80°C.
Check if the evaporator heats up.
Check the engine signals, petrol injection time, RPM, ECT, lambda
Let the engine run idle on LPG.
Adjust the evaporator pressure. Refer to the parameter list ( or F2 : ID box) for the idle level value
set.
Adjust the evaporator pressure in such a way that the pressure measured ( P-sys ) equals the idle
level value.
Turn the socket-head screw at the front of the evaporator to adjust the pressure.
An error code will be generated whenever the pressure variation is to high.
Seal the evaporator with the sticker included in the delivery after having adjusted the pressure.
7.
Use the diagnosis software to check again all input and output signals.
8.
Check the system for error codes and solve these, if required.
Check the petrol MMS for EOBD error codes.
Place the protection connector on the VSI communication connector.
9.
Make a test drive and check the driveability on LPG and petrol.
