  • Scan from track run

    Got this scan while at the track yesterday, wanted to see what you guys think about it. Any thoughts are appreciated.

    Time wasn't as good as I hoped, but the density altitude was 2100' and my clutch is slipping on the launch.

    The full time slip:
    60'....2.230
    330'...6.166
    1/8....9.422 @ 75.18
    1000...12.226
    1/4....14.565 @ 96.84


    The scan:

    Things I notice:

    </font>
    • Injectors are maxed out at almost 95% at 6000 RPM.</font>
    • Little bit of KR at random places, but not too bad.</font>
    • A little rich, but not real worried about that, since it's much better than it was.</font>
    • Random drops of manifold pressure?
      Frame 143-144 is a rather large drop. From 102-94 kPA...that's a drop of almost 2.5 in Hg in the middle of a WOT run! My air filter is pretty dirty, maybe that had something to do with it?</font>
    • Airflow drops as well?
      Frames 143 through 153 show drops in MAF airflow as the RPMs continue to rise.</font>
    • MAF frequency of 9870 Hz @ 5981 RPM (Frame 152) corresponds to an airflow of 672 mg/cyl. Spark tables only go to 680 mg/cyl....am I close to maxing out that out? What happens with a higher airflow?</font>

    Thanks for any comments. [img]smile.gif[/img]

    very nice..you could definitely see 13s NA..as far as this..

    "Frames 143 through 153 show drops in MAF airflow as the RPMs continue to rise."

    i seem to always have that problem too..i dont know if it has something to do with PE mode or what..but im yet to figure it out too..always drops a little for about the second 1/2 of the run
