[s-cars] Pinging w/MTM 1+

[Ned Ritchie]

Scott,

You're correct.

Please note this:  I've bought some "old" race gas that was lousy that
had sat around for several months after a racing season and the Audi
Club folks bought it at that track with poor results.

Would you explain this further?  I understand this is the case to get
the
benefit of being able to advance timing due to better gas.  But it seems
to
me, that detonation would be retarded as soon as a higher octane fuel
was
available to burn.  Am I mistaken?

Thanks,
