Sorry, didn't realize that there was an ecm section. Maybe a MOD can move it? Or i'll repost in that section.
Ill look into this setting. Where should it be set?

no need to be sorry , just that if you post there you'll have a better chance of reaching those that play with XFI
second yellow is under 2 degrees knock and the XFI may very well ignore that
ive heard some say ignore the led knock gauge or get rid of it , well knock is knock and while it can go off due to mechanical things like rockers and such if tuning makes it go away its not mechanical clatter
light knock if the tune isnt corrected or the cause isnt fixed can become heavy knock given different conditions
as far as this thread the opening post and replies really should have been focused on isolating and fixing the breakup issue instead of being concerned why its not showing on the xfi
at what boost level/rpm are you at seeing knock and what timing are you running (i do see cal tune so i would assume its on the safer side around 20)
breaking up could be
ignition related ...a weak coil / bad plug/bad wire/ crank signal
valve train related ....a broken valve spring, bent pushrod or collapsing lifter,
fuel delivery issue.... not enough pump /injector or line for the e85
where is a log of the trouble
