based on the logs i can tell you that the engine is indeed running
These look completely normal to me. The concern with IAT sensitivity - it's not as sensitive as folks make it out to be w/r to needing an aftermarket IC and timing pull on a stock or stage 1 tune. Your ECU targets torque and adjusts timing/boost/fuel to reach it based on a host of parameters. There are many variables and you will see some normal variation which is what you are seeing. Tune your car and enjoy it, there are no signs that you have any issues to be concerned about based on all of these logs. I log my car all the time and see some variation log to log..it's normal.Some better logs with better data resolution from last night. Added a/f ratio.
Note: These logs did not include any knock sensor readings. Something about adding knock sensors to the log recording absolutely murders the data rate. Looking at the CSV, it appears the sensor data doesn't come on congruently, but rather one after the other, so it basically cuts the data rate by 4x. I even manually input the PIDs for the knock retard outputs, and still it killed the data rate. However, since I haven't been recording any knock in any of the prior runs, I don't think knock is an issue anyways. But it would be nice to figure out how to make knock sensor recording work.

- Here we can see timing dips from -3 to -7 in a split second.
- IAT's around 100-105F. Is this a normal timing pull for that IAT?

- Compared to the above, the IAT's were roughly the same, but the timing didn't dip to -7
