i re strobed the car today, but this time i put the strobe at adifferent
angle and was able to make out 0, 6, 12, 15, 18 to name but a few markings,
as it was id timed to tdc with 15 degrees advance on the strobe, and that
tied up with the 15 degree mark, so i advanced to 17 degrees or there abouts
and will drive it like that for a few (hopefully hot) days and check the
fault memory for knock.  I am right in thinking that i should advance the
timing as much as possible until i encounter knock and then back off a bit,
is that correct?
