Knock question

936 Views 3 Replies 3 Participants Last post by  zax
I finally got my Cobb AP and the MAPerformance Stage 1 map. I have feedback knock as one of my gauges. It remained at 0 until I was on the interstate and had the cruise set at 75 and then I noticed it do some fluctuating for a few seconds and hit -2.78 then back to 0. Is this normal when cruising on the interstate?

long story short, its what is called cruise knock. Pretty typical. Was your climate control on? Thats usually when you will see -1.41 feedback knock or slightly more. If your getting any higher then regularly and espacially during a WOT pull then you should reach out to MAperformance for guidance.
That's definitely what it is. If I don't turn the A/C on at all, then the feedback knock stays at 0. Once I turn the A/C on and get on the interstate, I'll get the -1.41 or -2.87(or -2.78). And it's always 0 during WOT. This MAPerformance stage 1 map makes a huge difference compared to stock. Loving it so far.
Low load knock events are generally harmless or simply false knock. This is relatively normal to me.
