Spark knock

I just had trackey installed and I hear a little spark knock . I am running 93 octane as well. I thought I heard this at times before the install but seems more prevalent now. Any suggestions? I plan to add BG44K.
It's due to the overly lean Air Fuel at WOT they command (.870).
Knock sensors are dialed in for Spark knock, not lean fuel pinging.
I will definitely read the literature but from what little experience I have with Trackey I can tell the car really comes alive and the exhaust note changes quite a bit. Can't wait to really explore the cars capabilities. :)
