I got in this issue
in VCM scanner reading spark advance [sensor] at high revs and high load I never read more than 24?...............
Then I did some test (disabiling correction etcc......) and at the end i discovered that is not true........infact if I put 30? in the map in this area I read 30? in base cyl1 advance with no correction, and I clearly notice a starting of detonation (so definetely spark advance is increased) but in spark advance sensor I alway find 24?
It's a big mystery do you have any Idea?
should i read a different spark advance?
