    Default How and what to log for rough tune?

    Guys I am saving up money for a wideband 02 sensor. Until then I've done some tinkering with my buddies '04 6.0 liter 2500HD. Of course the first thing we will look at after re-writing the PCM with my guesswork is if the truck drives normal and smooth. Assuming there are no hickups, what should I monitor, and how do I set up the Flashscan / Scan tool so that I can monitor this data while he's driving? (hehe, I hope I didn't "tune" his tranny too much).
    Thanks.

    For basics, you can log the PID's described in the AutoVE tutorial. You might want to wait until you get a WB before you make too many changes.

    I tinkered with my timing, throttle cracker and throttle follower while waiting for my WB. It made some noticable differences. You might check the differences between say a stock Vette 6.0 liter and your buddies and tweak from there.

    Those 4l80E's are tough , I did a TransGo kit in mine and tuned for it , shifts just like I like it , firm and fast at WOT and not so firm at PT with out slush shift .

    Success! I built a custom tune for the LQ4 from scratch, and you can actually feel the performance improvement. It runs and shifts smooth, and now smokes the massive aftermarket tires.
    However, I was unable to LOG anything. I think the Flashscan is capable of logging 20 minutes of driving without the laptop. When I tried it just said: "This screen is reserved for recording". How do I do it?
    Also, I was unable to get the gauges to work on the dashboard in the Scan Tool, even after I clicked "Connect". What am I doing wrong? Thanks.
    I love EFILive!!!

    V2 is capable of much longer standalone logging time (depends on size of memory card added) Unfortunately this function isn't available on V2 (yet, coming REAL soon ) hence this is why you see the "reserved" message on the v2 screen
