I'm not a pro by anymeans however I'm trying to understand my datalogging to see if everything is running as it should. I did multiple WOT pulls and Lambda stays pretty steady at .84 (which I understand is good) however knock and spark seems to vary during the different WOT pulls. During one pull knock went up to 5.25 and spark dropped to 21.75, on another pull knock was @ 2.75 and spark was @ 20 flat while on the third example knock was @ 3.5 and spark @ 23.5. This is with a 93 octane tune on a '14 GT.
I know heat will play a big factor , however temp never really got above 205 according to the datalog. Do these numbers sound good and if not is it possible it was simply bad fuel?
