A method eliminates detonation in an internal combustion engine (10) by identifying conditions that identify the imminence thereof. The method centers about the pressure inside the cylinder (16) of the internal combustion engine (10). The method tracks the pressure and when small rapid changes or fluctuations (38) in the pressure occur, the ignition timing is advanced for that particular cylinder (16). An alternative method utilizes a model of pressure based on an array of inputs and how the pressure should act based thereon. The method may also be used to maximize performance of the output of each cylinder (16) by retarding the ignition timing until the small fluctuations (38) appear. The ignition timing could immediately be advanced to prevent a detonation thus identifying a maximized output performance without reaching a detonation condition.
