I dont think this is the case but wouldnt hurt to ask. Do you have everything in the primary table? If its not in that then it wont read when logging.
Did you get this config from somebody or did you make it yourself? If you got it , your going to have to make some changes for everything to work properly.

Sounds like you have a bad config file or a communication problem. Any scanner should be able to read TPS and all those default data items in the PCM.
What tune are you dealing with? From what you are saying it sounds like you need a better starting point if you are trying to learn from scratch.
Not to sound like an ass, but if you are just learning to tune, starting to save a bad tune will not end well. Start with a known good, safe tune and learn from that. Not something that has issues and isn't logging properly or whatever.

I am taking everything as adivce and insight. I will say that I did not do this and have not started my own tune yet.

peak cylinder pressure happens at peak torque. If you tune your part throttle around knock, you are losing mpg and response. you can hit a bump in the road and showed knock.

What I was saying it whether part throttle or full throttle the AFR is in the 10's at the same RPM's in different gears. AFR around 6500RPMS is 10.4-10.5 regardless of gear.
Basically the car either cruises around 14 AFR or jumps to the 10's under any increase throttle postition.

^not crusing areas, light load, sometimes you lose efficiency by backing off the timing in areas where more timing could be added, considering we don't have different tables for load, we cant push timing in light load areas without getting knock in medium load areas. Because of this we lose bottom end torque. Also considering the lack of cylinder pressure knock at low loads doesn't have the effects that it does at high load. That would be my understanding of it.
do you have your rear o2 sensor out?

0 in hg is .52 g/sec on the logs/calibration file. above this in the timing map i had area's in my car upwards of 56 degree's of timing. only on decel would those get this. the car averaged 42-47 degree's of timing at part throttle. then ramps down the closer it gets to .52, then above .52 g/sec it would drop lower as boost went up.
BTW deviation from the stock timing curve will result in a loss of power.

Here is a quick log of the tune that is in my car now. The one that brought up my questions.
