The help doesnt explain in what circumstances the tune should disable the O2 heater. Can someone point it out or chip in?

When tuning. when you are done tuning put it back in closed loop. If the part throttle has been tuned right you should only have a few percent short term correction and and as close to zero as possible of a long term correction.

Thanks. I was asking about the O2 HEATER. Appreciate any clarification.

o2 sensors work correctly, when they work in their projected temperature range.

the heater shall make the sensor work faster, since in circumstances, when the engine is cold (starting the car is the morning) it isn't warm enough to give accurate values back.

in other cases the heater just turns on to check if the temperature is right... if not - heating... if ok - don't heat.

just look at the heating sequence of your wideband... and you will figure out how that works ;)

makes me think this feature was for the mix 'n match ecu/wiring and engine, no?

It is also there for those that run a wideband instaead of a stock O2 sensor.
