That was me driving around for awhile, and stopped for a minute or two because I heard a noise that turned out to be a rock in my tire treads.

You're recording at an 18-20 frames per second rate. That's not necessary. The PCM only updates 9 times per second. You could go to 5 frames/sec, and reduce the size of the file by 70%, without losing anything.

Haven't looked at the logs, but when I read this:

I immediately thought "wiring"

and then the very next post says:

I didn't look at the record rate, I just clicked log...I'll look into the recording options.

I made a shorter run. I tried lowering the record rate but it won't let you change anything. So I did a shorter drive this time, trying to hit all the cells I could and getting some WOT runs in. I also, after the run, backed timing down where it was needed to get rid of spark retard. Hope this one is easier on the eyes. HA.
