I added the e85 sensor to my 2018 silverado. I am running 70% right now. In a log today I noticed 3-5 degrees knock retard. Being at 70%, I know this cant be real knock, esp when the tune is set to 10-15 degree in those areas. The main spark advance channels all show 0, knock learn is 0, no burst knock.

Can anyone glance at my log and see if anything sticks out? I can log more PIDS if need be.
Thanks!
