I just converted to E85 this week and I now have 1-3 degrees of knock on my 3.4 pulley when I used to have 0 on my 3.2 pulley
Doesn't seem to make sense to me
Here is my tune

and here is my 40 min scan (WOT towards the last 10 mins)

I am fairly new to tuning but I though everything I did was correct
I scaled my 60# injectors to 42 and that is it, I had the commanded AFR at 11.7 but when I saw 8 degrees of know I moved it back to 11.0
I should note Histogram 10 is my Wideband
Any help would be appreciated as I though E85 was a super knock suppressing fuel.....
