If it's staying that close to -1.0 then you're OK... looks like it just hit a bit of knock temporarily, and that's normal. According to Cobb, as long as it stays at -1.00 nearly all the time then you're good... Their web site actually has some good info on it: https://cobbtuning.zendesk.com/hc/en-us/articles/204049644-Octane-Adjust-Ratio-OAR-
