Above: Centrifugal advance curves only (for comparison)
Max Vacuum advance is quoted as 12~16 degrees for both DG and DJ (see below)
SteveW: Using a 2.1 DJ distributor for a 1.9 DG
I think that they are probably close enough and the engine is running a treat on LPG and a quick check on 98 ron seems Ok too.
HarryMann: Good to use the correct distributor if you have one, though the curves do look the same slope.
