What is the perfect 02 voltage on a 1g?

[chanley talon]

Ok i have read 2 different threads or fact right ups . I have found one says that a 1g under full throttle on a logger should be reading .96 volts to be in the perfect fuel range? Not to rich or lean? Then the other says .88volts . I dont know who is right or wrong . I also read that there is a big difference between .92v and .96v in power that is . So i need some real answers. Or basically what am i trying to accomplish on my logger . For perfect o2 values. Thanks

They are both wrong! There is no perfect narrowband O2 voltage on a 1G.

You'll need a wideband O2 sensor and controller if you want to tune by o2 readings. All the narrowband O2 sensor can do is maintain 14.7:1 for closed loop operation and warn you if the car for some reason goes lean.

Ok so tuning a 1g with out a wideband what do i need to wacth to seee if i making a good run and where so these values be? I figure i should watch timing and knock but i need to know what is good in these categorys. Thanks.

I have the same question about where the O2 voltage should read on the logger at WOT. Mine is reading at .60-.72 range at WOT. I understand the need for a wideband to tune with but I'm not tuning I just am trying to figure out why my readings seem to be so far away from everyone elses.

Ok I feel like an idiot. After reading some more I realize that the narrowband is worthless and I won't bother worrying about it anymore.
