could someone please help me with an ignition advance table? i have been
trying to get one without any luck. any information would be apreciated.

 

The quest for this info...regarding any Jaguar models.... has been ongoing for years. Personally I've never seen the timing curves/tables published in any Jaguar technical publications.

I'm sure the information is out there somewhere...most likely in Lucas technical literature. I just have to think that a master book or chart was published at some point. If so, how many dusty, never-read copies ended up in the trash bin after 10-15-20 years?

I think the vacuum advance modules are stamped with info that can be decoded to reveal the some information of the timing curve but, of course, vacuum advance info alone doesn't tell the whole story.

Sorry I can't be of any help

Cheers
DD
