EGR ignition

[Awsomsauce]

Can you define what this is. Does EGR stand for exhaust gas recirculating or something else. What do the EGR numbers represent?

The column index is the percentage of combustion chamber charge that is exhaust gas. It is mainly used at part throttle. At full throttle the knock ignition limit table more or less controls ignition.

So if I were looking to tune the ignition for more advance timing in the ignition, for more power, which ignition table should I be looking at? I know that the ecu uses an algorithm to determine ignition timing according to the Hondata video on tuning the x gen. But it appears there can be some tuning done still.

Knock ignition limit table.
