[Gmecm] Re: Fuel Economy

[Tom Prucha]

I've been running TiO2 sensors for years on my Buick by using a resistor 
between the signal output and ground to get a nice 0 to 1V resultant 
signal.  I don't know if the the new ones will still do that or not.  
TiO2 is also nearly immune to lead fouling compared to Zirconia.
