o2 sensor voltages?

this question pertains to lancers with no fuel mods. just maybe an intake and/or throttlebody. for those of you with some kind of a/f gauge i need voltages at WOT throughout the rpm band, cruising voltage at 35 mph and at 65 mph, and voltage at idle.

well there, i asked. i do know what the ideal voltages are supposed to be. i just need to know what everyone else is getting so i know if these lower figures i'm getting is the way the lancer operates, or if i just need a new o2 sensor and/or wiring. they're a lot lower than what i have read. my idle peaks at .80v, cruises to a peak of .75v and after driving normally around for a while, my o2 sensor seems to only get up to .86v and doesn't read any higher. all figures as of an hour ago. well okay thanks.
