So I've got my wideband reading between 12.7 and 12.8 using the inTuner. From what I've learned so far, that is enough fuel.

I logged a pull and I got a knock reading of 3.2 at 4075 rpm and another one of 1.9 @ 4125.

Any suggestions to get this lowered? I'm unable to see what my injector duty cycle is. I'm on stock injectors with LT headers, 3" exhaust, and a k&n intake.

I could add more fuel, but that would make me a little rich. I also have the access mess with the spark a little bit.

Please educate me!

Attached is the data. If you'd like me to add more data to the graph, look the left at options to view and I'll post another pic.
