Pull with little knock, then a pull with lots of knock... How to Tune?

And your post was not helpful at all. My first log shows little to no knock. I'm not asking how to tune. I'm asking why one run there is no knock and another run there is. And if someone is going to give advice on how to tune, they should give correct information - which is all over this site. Map Trace is just another flavor of tuning software that I'm personally not familiar with. I've used EVOscan's ability to map in real time the load cell and corresponding careabouts - AFRs, knock, etc. I don't have a question about which load cells I'm in when I'm knocking nor did I ask if I'm running too lean. I know that on an EVO 9, it's best to be around 11.8-11.7 at peak load, but I'm not going to adjust my fuel until I know what really causing my knock and if it was due to running lean (higher temps), then I would have expected that my first run would habe been knocking just as much. Unless someone wants to say that the difference between the runs is that the first run heat soaked the engine/raised my temps enough that by the second run a minute later, the higher temps were enough to induce such high counts of knock.
It's a simple question of those who are experienced tuners, asking if they've seen something like this before and what to consider.

You have lean spool enabled in your rom Disable lean spool tune car for desired afr then turn it back on and monitor afr . Also heres the map smoothing tool. Attachment 249261

OPTION 2
1.) Go to "boost enhancement (anti-lag) Stop RPM"
2.) Right click on it and select "edit map"
3.) Change the address to "1284", click apply, then OK
