Hi, Im currently investigating using LPG on my FD3S and I'm trying to solve some issues with what ECU I'm going to use. The gas injectors are much smaller than that of the petrol ones. The biggest a single injector can be is equivalent to about 500cc petrol injectors.

I'd like to keep the powerfc as the main contolling element because my regular tuner knows it inside out. Then the calcs for the conversion between the petrol signal and LPG injectors controlled by a seperate ecu because fuel pressure correction isn't built into the pfc software.

If I use for each of the rotors 1 injector as a primary and then batch fire 3 injectors as a secondary. Would this be possible ? The load of the injectors would be on the seperate ecu and only a simulated signal would be sent to the ecu.

Has anybody done this with a petrol setup using a FJO High impedance module so you can run secondary injectors in parrellel and not overload the powerfc ?
