Part Throttle Knock Issue
Wondering if someone wouldn't mind taking a look at the attached log and giving me some thoughts? Car is a 17 Camaro SS with longtubes and ported msd. The tune was done remotely a couple months ago and seemed spot on but I had always had at least 35% ethanol in the tank until just recently. Been through a couple tanks of 93 and noticed some audible knock at part throttle with the pid on the aeroforce gauge giving readings up to 6 deg pulled. Assumed bad gas but have been through 2 tanks with no change....and also no knock at wot, so not sure if that's still a possibility. Ran the attached log and noticed that my stft's are adding a lot of fuel when it happens. Can anyone offer some insights? Hoping it's something little I can adjust myself but am pretty inexperienced.
Thanks!

Little too much timing in that range was all.
