O2 sensor weird voltage

In this video's video is my o2 sensor voltage on a CG13DE with CG10DE ECU (swapped just the engine).
The spark plugs tips were dry and light brown color which could indicate a lean mixture. Does anyone know if this is a faulty sensor or pump/injector/pressure regulator/ecu map?

Engine has a new gas filter, 1.6 primera airbox, and 1mm head skim and original cg10de ecu.

While driving normally and at idle, voltage jumps back and forth between 0.1V and 0.7V ish. At full throttle, it hits a maximum of 0.8V and reaches like 0.6V or 0.55V.

(In the video voltage is in mV)
