Come to think of it, if we assume for the moment that shift knock is a real thing on a stock car, which means gear clash is being picked up by the knock sensor, it begs the question, are Fidanza single mass Flywheel equipped cars more likely to experience false knock? The transmission noise of a single mass equipped car is well documented up to about ~2k rpm. Is that noise, under various load and speed parameters, generating false knock throughout the rpm range as we shift and move on and off throttle without the dampening affects of Dual Mass Flywheel? Food for thought.
