When we are talking non-Si ECU's, with stock internal engines, this simply doesn't appear to be the case. Even completely stock cars will consistently raise the knock control value at higher engine speeds, even when total ignition advance is removed by large values (just resulting in a major power loss feedback cycle).Have you looked into the adding of any aftermarket parts/tunes that could potentially add background noise, throwing off the knock threshold map, and in turn falsely adding knock control?
The knock sensitivity tables on Si (5AM) and non-Si (5AA, 5AN, etc) ECU's are IDENTICAL. The knock retard multiplier tables have identical values above 5,500rpm between the files. They have identical knock retard tables. The rise in knock control above 5,200rpm (in the event that there is no significant actual knock sensor activity adding insult to injury) appears to be a background behavior. There are quite a number of tables in the ECU that are still unknown in terms of function, and we are constantly working to test said function.
I hope this sheds a little light on the subject, and I apologize for a miscalculation regarding another shop's downright false dyno number inflation.
