Well, I don't know that I'm "totally off base". If I had been right that the "knock correction" value indicated the amount of timing the ECU was pulling in order to correct a knock condition, then I'd say I was pretty on the money. Don't blame me because ECUExplorer/Subaru decided to give the value a poor name.
