I only looked at the top log file but it appears there is something wrong with your lambda instrument, ignoring the odd spike it really only varies between 1.0 & 1.1 lambda so I doubt that reflects reality. You need to fix that before you base any tuning decisions on it.

The jerking effect on lift off/overrun is generally too much ignition advance.

This issue was sorted with fuel adjustments and the main problem was the timing as advised above
