All torque converters have a stall speed and the ECM knows nothing about the amount of torque the engine is producing.
it does a hell of a job of guessing at it, though. my car was making over 350 ft lbs of calculated torque which in turn made KR appear in the form of torque management and transmission safe guards. once i pulled all that my car didnt ever knock again. then my transmission bit the dust. good times.
