i've read all about the BBM going onto EA-EDs in a few thread. first of all, are the EF and EL BBMs the same? and secondly everyone says u need a huge list of things:

BBM
EF/EL TB
EF/EL Accelerator Cable
EF/EL ECU
EF/EL Injectors
EF/EL Vacuum Switch
etc

but this is for a car on petrol. coz i'm running of LPG can i get away with just the BBM and use my EB TB and accelerator cable and EB ECU (isn't controlling jack s**t anyway - except spark)

problems i can forsee with this is that:

1. accelerator cable wont wanna bend properly
2. activating the broadband-ness
is the broadband-ness activated electronically (to activate the vacuum mechanism) from the ecu or is it all pure vacuum?

is the later is true then can i just put the vacuum line of the butterflies onto the manifold so they activate according to the vacuum or will this fail miserably?
