Advanced spark timing was explained as follows to me years ago;
If you want a woodpile to burn at twelve o'clock you don't light it at twelve, it will peak burning 10 minutes later, you light it at ten minutes to twelve, it will burn at maximum rate at twelve.
Same with a fuel mixture.
Does a modern ecu actually have a p.i.d. for the ignition timing and can you see it change in live data?
