-> Any pros to advancing base timing?  At least for testing purposes,
-> you could use it to determine max advance.  Why are you looking for
-> more advance?  No knock at present settings?

 Advancing base works just fine.  GM's spark control strategy for the
'90 Corvette was to continually step the advance up until it saw ping,
then back off, etc.  There's a software limit to max cruise advance, but
a quick workaround is to bump static.
