The main spark table is about as easy as things get to find,  with something
like promedit, winbin, and reading Programming 101, shouldn't take much at
all to find it.  A burner is like $130, and hunt up a spare memcal, zif
socket and for less that $200, you can be doing it right (with hunting,
probably could cut that in about 1/2)!.
   While the list does go off on tangents, it's about gmecm's.  I do some
advising, about tune-up as that relates to EFI, but when we/you go just
looking for mechanical fixes, that just defeats what my intent is.

I sure hope you don't honestly mean that.
