I did not do the tune on this vehicle in question. Im just scanning and looking at the data. Is it possible that another "tuner" went in and desensitized the knock sensors so they are not picking up knock when they should. For example at low rpms under load I am 100% positive I hear a tiny bit of knock but when im looking at the laptop during this time period I see no KR.
So is this knock all in my head or could I actually be having knock even with 0.0 KR?
