I assume if the ecu will auto callibrate that it uses Ve or volumetric efficiency mode, the tables all seem consistant, that makes it unlikely to be a leak, the values would be up and down.
Looks like the engine was cold in the first table and warm in the last, presumably you calibrate when the engine is warm.
I dont spose you have tables from when the engine was running well?, that would be usefull.
The correction constant or trim is a value determined by the ecu, it chooses a value from the table, then looks at the exhasut 02 sensor, if the mixture isnt perfect it will trim the values from the table, then store this trim value and use it next time, the table isnt changed the ecu just modifies the value pulled from it.
If the trim is high or low because there is something wrong with the engine, usually higher than 10% you get an alarm.
Another thing that can cause driveability issues is a bad 02 sensor.
Are you able to check for fault codes?, are they even supported, some gas ecu's are very simple and may not do it.
You could try a drive cycle check, the ecu tests various stuff during a drive cycle, drive along the motorway at 60 for at least 5 minutes, then pull off and let the engine idle for 5 more minutes then switch off for 5 minutes, this should make the ecu go through its drive cycle, if something is wrong the check engine light (like I was saying if supported) will come on.
