Hi all,

I did a scan today and I am having issues with high knock. Going by my scan it looks like I need to add fuel, especially in the 9000hz and above. The wideband readings are at 19.6 which I believe is the highest it will read. Also it looks like the narrowband o2 reading are a bit low as well. My question is should I add fuel to these cells? Since they are so lean should I add at 4% or just do 2% at a time. Does this look like the correct thing to do to correct this knock issue?
