Alright, I finally got a good bit of data. I actually drove the truck to Pittsburg, Kansas and back. Its about an hour and a half one way. I went at about 55 mph, and the truck did well. Below is a link to my logged data. There is quite a bit there, Bill (and others), and I have been trying to compare it to what I believe is a standard set of data from Binderplanet. The biggest difference that would affect some of the other sensor readouts is that the standard data was from an engine running at 1000 rpms where as mine was at almost 3000 rpms.

I am not totally sure what each line means, but three things that stood out to me. My MAP reading seems high and inconsistent. My oxygen sensor readouts are erratic. And finally my lean / rich counter is all over the board.

Any thoughts?
