In my tecGT with the older software, Electromotive had built in a .08 buffer on the TPS that they do not really clarify. So, in effect you need to add this to your TPS zero point to ensure the EXU considers the throttle closed. So, for example, if your TPS zero's at .94, you would need to set your TPS zero to be 1.02 (.94+.08) to ensure the ECU recognizes the TPS is at idle. You may want to try changing this value. You can always change it back later...

Looking at your graphs I see your EGO corrections seem to be quite high in both directions in good and in bad graph sets. You may need to keep tuning your AFR map and/or your fueling map. In the good set of graphs the AFR seems to bounce around within what you would think are good values (between 11 and ~15?).

When I look at the bad graphs, it looks like the AFR's are out of whack and it looks like the EGO correction is much more in play. Is it possible your O2 sensor or your EGO functions are not working consistently?

If you trust your fuel map enough, you might try turning of EGO correction. This would force the ECU to rely upon your fuel map without correcting it, and I think it would more or less also ignore the O2 sensor, I think. May be worth looking at your options here, as between the two graphs sets, it seems these graphs are quite different.
