it is running the BRC vapour injection system, yes it has its own map sensor and I believe that it is looking at rpm as well as both O2 sensors
when it changes from petrol to LPG the gas ecu itercepts the petrol injector pulse does its bit then drives the gas injectors

I have finally got hold of the person that did the original gas install and hopefully he can sort the lpg side without the need for me to run dual maps

if this does not work out I will look into going the dual table route so it can switch on the fly
