 I was reading about various sensors last night ... said the zirconium
dioxide (that's right, isn't it ??) sensor has marked different
characteristics in things like Vout, Zout, and response time
above and below about 350 C.  Above 350 C, Zout drops, accuracy
improves (Vout more meaningful) and the response time (as I
remember) is about 50 mS from rich to lean and versa vice.

Does anyone know the actual Zout of the EGO ??
