The MP computer is hi-performance computer and will advance the timing
and alter the air/fuel ratio for more performance. It's my understanding
is that advancing the timing too much results in pinging (detonation) and
that, if anything, the timing should be retarded if pinging is experienced.
Hope this helps.
