In the first run, looks like air/fuel is lean. Optimal is .87-.89V, and timing is pretty good. The second run looks better, but O2 shows you're running quite rich and the timing is also good. Some people try to target timing at 18 degrees. Did you do anything different between runs one and two? Just curious about the difference in values.

It looks like you're just a hair lean and pulling back a small amount of timing. You should see 19-21* advance normally, and about .92 - .94 on your stock O2 sensor.
