I have a 98 Disco V8i and I am in the process of installing a HHO system to increase mileage. I need to know the voltage output range from the O2 sensors and which way the output affects the computer. Does a higher output indicate lean or rich condition?

Thanks - *****

 

not sure on max, but opperating range is 0-1 v, lower is leaner

 

I just found this doc that may be of assistance to the HHO setup...
