I wanted to quote and point out that this is NOT true. There really is no such thing as "safe AFRs" in a vaccuum. It is not safe to have 11.0 AFRs across the board with 25* of timing. Also, it would probably be safe to have 12.0 AFRs with low boost and low timing, though not optimal.
AFRs cannot be tuned alone. It's an intricate balance between AFRs, timing, and boost. There are also many other factors that come into play, but those are the main 3, and you CANNOT tune one while ignoring the others.
I don't recommend trying to listen to knock or worrying so much about a knock sensor. Just use logging software that shows knocksums and timing along with the wideband for AFRs.
