Xcal 3 data logging with Livelink

[V8XTasy]

hi, I've been trying some data logging with the live link s/w on the SCT. Get get to the screen where it comes up with all the PIDs you can select. There must be 200 or so which are selectable, I think you can select 20 at a time.

Question is, a lot of these return a value of zero or have very brief names or some even sound very similar to each other. Does anyone have a list of which PIDs will actually return a useful value to save me having to check through all 200+?

cheers
