Compare data logs?

Hey guys,

I went to the track about three weeks ago and did some tuning and making good progress.

I went back last weekend and now I'm alittle confused. The only changes was the outside air temp. The heat index was 108*, where the previous run it was probably 65*.

Here is a picture of each lot showing RPM, Inj Duty Cycle, Actual A/F Ratio, and target A/F Ratio.

Notice on the 2nd shot everything is real jumpy. What would cause this?

Did you change the max logging rate between trips? Appears to be a rate change, you did log one less sensor, don't know if that effected anything or not.

That's probably it.

Thanks.
