The ecu will always try to compensate. By doing this mod, you're pushing the advance limit higher.

For example: We'll say the ecu can do a max spark advance of 60*. If the ecu detects knock, it will scale things back until there is no knock. Push the physical connection to get, say a maximum effective spark advance of 64*.

Your engine now has the ability to run a higher spark advance but still be able to scale back in the event of knock detection.

Highest power output for combustion occurs just before pre-detonation.
