What? super knock code simply means that there is knock occurring that the DME cannot fix by pulling timing. There is logic in the DME to prevent knock and timing will actually trend downward over time to some degree if you get knock in a specific area of the rpm range consistently.
Blown piston and knock codes on a tuned car means the owner didn't know how to read a log and/or have the experience to hear/feel the glaringly obvious issue that must have been going on... Can't immediately blame octane (could be in part due to hardware), but, it's likely the car was tuned too aggressively for the octane available.
