That is what I am hoping someone can tell me .... some idea of what is
going to fall out when I start pulling this thing to bits.
The Rave CD gives me all I need to know about my Disco and RR Classic
before I start a job, but these LPG systems seem to have no
do***entation. If it helps the eva****ator looks like OMVL. It is
closed loop with lambda sensors which starts on petrol and switches to
LPG after a few minutes.
