I zero'd out all the knock retard stuff on my engine. With the roller rockers and headers it was retarding the timing to the max almost any time the pedal was being pushed.

From my understanding, the only way to change when knock is detected is by changing the knock filter. There are claims the knock detection can be tuned, but it's really just tuning how fast it retards timing and how much it retards timing. I didn't see anything for the thresholds of knock or anything like that.

No-one knows what's inside the knock filters and the LT4 filters are stupidly priced these days. I'm sure it could be possible to reverse engineer the filter since it's likely a passive component filter, but I can't be bothered. I tuned it fairly safely and am aggressive with the transmission so it doesn't lug the engine to reduce the chances of actually having knock.
