istruggle2gate11 Posted August 12, 2006 Share Posted August 12, 2006 Hi all, Im installing an LPG system into a 1989 Rangie with 3.5 Flapper injection. Its second hand but never fitted system, all parts are there but unfortunately I cant rely on Tinley Tech for support as the system was bought new 3 years ago. All the hardware has installed fine, Ive come to the wiring up part now, and have hit a cross roads... The kit comes with a switch and relay which when wired up to the rev counter signal it turns off the injectors and activates the gas control solenoid/valve. According to the wiring instructions, I only need to intercept the wire from the injector relay. This would then leave power to the ECU and fuel pump (I know some gas systems leave the fuel pump running but I would rather just turn it off). I would much prefer to use the LPG/Petrol switch to turn off the ECU complety, which in turn would cut the injectors and fuel pump. Is this plan flawed? I assume that the old flapper type ignition doesnt require the ecu to be powered? Im not bothered about "clean" switching, worst case, I start on petrol then restart on LPG when the engine is warm enough. Ta Quote Link to comment Share on other sites More sharing options...
