got 2* of knock at the track, need some help A couple of Fridays ago i was doing some data logging at the track, i noticed 2* of knock @4000 rpm, map was @ 100 during that spike as well, i don't quite understand it yet but i uploaded my tune file and my data log, maybe you guys can show me a few pointers on what i should adjust to prevent this from happening, this pass was my best pass to date and resulted in an 11.73 @ 116mph with an lq4 370 fbody car.
thanks in advance guys, i'm off to some more late night reading

You might be hurting your power curve looking at your flat timing. Set your scanner up to look more like a dyno, log your dynamic air & dynamic cylinder air. Use those airflow #'s as your HP & Torque curves just as you do on the dyno. Drag street is an awesome dyno.
Then remove the KR, maybe even reduce the timing in the peak torque area & you will most likely see the power improve.
What about a WB?

i will add those PID's shortly and see how they vary from log to log thank you.
I made a little error in the "Drag Street", I'm sure you understood I meant Drag Strip! Anyways here is screen shot of what I'm talking about
We made some nice improvements with this memebers C5 using this configuration.

Do you know how to setup these PID's? im having a bit of trouble with setting up dynamic air, i believe i have dyn cyl air setup properly by adding the PID from the list.

stuff is confusing lol, i get that i need to have the scanner open with no logs running, but i can't for the life of me find those two PID's all i see is calculated air
