    Hello Mark,
    Your statement, "it will not show when on gas as gas is not regulated by ecu. there is no varible controll on the gas depending on drive conditions" depends on whether the lpg system is sequential injection.
    If it is a sequential system then the lpg ecu takes the readings from the injector signals(duration)calculated by the petrol ecu ,then controls the lpg injector duration accordingly.
    If the system is just a single point mixer system then the petrol ecu will have no effect as you say.
    Regards , Andrew
