Hi guys

I just did a data log, and through the entire log, my knock control is at 99%, and I just filled up 95 Octane. What could be wrong?

Thanks!

A number of things could be wrong.
Mostly the ecu is detecting knock. Your ignition timing might be a bit to aggressive or your knock control settings need adjusting.

At 99% Knock control your ecu should be retarding timing all over the place and possibly creating what feels like flat spots through the rev range.
