I have noticed my car kicking into the secondary maps when there doesn't seem to be any real knock, and I have definitely heard a bit of knock without kicking into the secondary maps.

Once you actually go to the secondary maps, it seems the car stays on there for some set driving cycle, and doesn't immediately go back to normal maps.

Thanks for posting the stock maps up, I forgot how goofy the stock ignition maps are from the early 90's Nissans....
