Thank you for sharing the site. It contains extremely detailed information as to the mapping of knock sensor inputs to the ECU. I had read somewhere that the ECU stops taking input from the knock sensor at 5,000 RPMs due to the engine making so much internal racket at that point that the sensor input could no longer be differentiate knocking from normal noise. This site indicates that there is a starting as well as cut off RPM point for input depending on engine type (NA vs. TT) and load.
The information would suggest a test to determine if the knock sensor was responsible for a safety boost condition or not though. If the engine comes out of safety boost at 5,000 RPMS then the knock sensor may be responsible for it but if it stays in safety boost, it would might indicate that it was the result of something else.
