I would second this.
My understanding of LPG ECUs is that they take the injector pulse signal from the car ECU and use that as its own injection trigger. The difference is that the LPG ECU will deliver a proportionately longer injection pulse as the engine requires more LPG than petrol. And of course it will be responsible for interrupting the signal to the petrol injector.
