Abstract
A method of verifying a default state of a control parameter in an automobile engine includes checking engine controller performance with the control parameter in both a default state and an alternate state. The results of the tests are then compared to verify which state is the appropriate state for the particular engine being tested. A third engine controller performance check can be made to ensure that the controller and engine perform in a repeatable manner prior to setting the state of the control parameter.
