Hi All

Fairly new to Land Rovers, and i do n;t post too much, however I'm after some advice.
I have a 1996 Discovery 3.9 V8 auto, with a sequential LPG conversion. Do any one have a idea to what to set the ignition timimg to? The hand book suggests 6 degs for petrol, but should it be advanced for LPG?

Many thanks

David
