For measuring the petrol injectors :
Interrupt each petrol injector control wire (injector min)Each VSI wire has a petrol injector / cylinder number printed on the wire, connect this wire to thecorresponding petrol injector / cylinder.
Connect the bicolored VSI measuring wire to the ecu side, ( wire code: ECU SIDE ).Connect the corresponding full colored VSI wire to the petrol injector side ( wire code: MIN INJ SIDE ). See diagrams: Installation manual general part 1 / 2.
Attention:
Each bicolored measuring w ire corresponds to a specific LPG injector and petrol injector / cylindernumber. Do not interchange the wires.

Checklist after installation
1. Connect the serial interface wire and run the VSI diagnosis program.Install the VSI 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 diagnosissoftware. When the VSI computer has not been activated, it will keep generating error code160. 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 comparethese 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 ora fluid detection like soap. Caution for moving and rotating parts in the engine compartment !
6. Let the engine run warm on petrol >80°C.Check if the evaporator heats up.Check the engine signals, petrol injection time, RPM, ECT, lambdaLet the engine run idle on LPG. Adjust the evaporator pressure. Refer to the parameter list ( or F2 : ID box) for the idle levelvalue 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 drivability on LPG and petrol.
