I do see the cause of the crazy timing numbers in the histogram though. If I watch the items list in real time I can see that the timing number is cumulative. It starts low and continues to climb higher until it gets to 100 at which point it resets to 0 and starts over again.
Correct. Your watching the O2 cross counts. That is what a stock bin file spits out in data stream.

Hacks are in XDF file. You are changing the data output in chip/bin first. Then data log and it will be in ADX data.

Spark Advance takes place of O2 Cross Counts.
Base Pulse Width takes place of Prom ID.

So stock chip/bin O2 cross counts and Prom ID are correct, Spark Advance and BPW are wrong. If you use the Hacks then O2 cross counts and Prom ID are wrong. We stole their place in data stream by telling the chip/bin what to spit out in data to ADX.

If you re-read my above post it should make sense now.
