based on the strange wires added to your ECUI would recommend that you try your ECU in a known working vehicle. If it still does not work correctly, then you should replace your ECU.

Hey There first post. How come in the second datalog you have an idle of almost 1500 vs in the first around 800-900? I also noticed looking at the datalog that was first uploaded the 02 Sensor voltage is acting different and not responding in the same manner. It could be you just had a bad o2 sensor? thanks.
