Datalogs of completely stock 05

I reflashed my ecu this morning and did a few pulls on the way home from work. I added some fuel in the 3k-4k range, and pulled timing in the 5k-7.5k range.
I'm only getting very slight knock in ~3.8k-4k, but still getting a fair amount at 6k+. Guess I'll pull a hair of timing in the 3.5-4k range, and pull a bit more at 6k+.
On this plot, I took one extra step and put the RPMs as the X-axis; let me plot one more variable on a chart. Still have to do 02 separate.... I like using excel though because I can manipulate things the way I want to. Plus, at some point if I'm really bored, I'll calculate tq and hp curves with the aerodynamic drag as a parameter.

). Lower it to 10 and I thing that will take care of things. A lot of the flashed cars that I have seen run 9-10* of timnig @ 6k with 91 octane gas.

On the top end I would try lowering 6000 and 6500, but leave 7k+ alone. Your knock is decaying above 6500 so you you are probably just seeing residual knocksums at 7k+.
Also, DataLogLab does factor in aerodynamic drag. You can also export the logs with the torque and power numbers back to excel.
