Is this your source?
If your assertion is true, what does the ECU expect to see at the o2 sensor signal wire for each type?

Redtop ECU's provide the voltage to the Skinny O2 titania sensor and the resistance in the sensor changes based on rich/lean. The Zirconia sensors have their own voltage they send to the blacktop ECU and the ECU reads that and the rich/lean condition is adjusted... This is what I've always known but if you care to prove me wrong by explaining I'm all ears.
