I've filled up with 93 octane from 2 different Shell station in 2 different cities, and both datalog sessions showed up to 2.5-3° of timing being pulled from the knock sensor. This was denoted by a positive value under the knock sensor category. All the AFR were in check with what was being commanded.

I sent the datalogs to me tuner, who is one of the best ones in the Coyote platform (not AED), and his email back to me said that everything looked good and made small tweaks.

Both of these logs have come in colder temperatures than what my car was datalogging in the beginning, 65-75° now versus 80-85° before. Can that possibly be causing the issues?

I just want to know that my car is safe to drive hard, and that I won't screw anything up.

I will gladly forward someone my datalogs to look into if you supply an email.
