Looking through the plethera of {EST.XXX.DMA} PIDs i notice that i actually have the following that represent "final Spark timing" .....and these are thier definitions as described by the EFILive glossary:
SPARKADV (the one Im using right now) ->Ignition timing spark advance for the #1 cylinder not including mechanical advance.
EST.BASE.DMA ->Ignition timing spark advance direct from the main spark map in use.
i.e High Octane, Low Octane, Closed Throttle in gear.
EST.RUN.DMA -> This is the final spark timing value after all modules have contributed.
EST.EQR.DMA ->Equivalence ratio contribution to the final ignition timing spark advance value. This value is controlled by the following Tuning Tool calibration:
{B5908} Fuel Mixture Spark Correction
So which of these would be best to log my total spark advance when tuning?
