What is optimal range for 02 milivolts at WOT?

870-920, but they're not accurate, that's the reason for the wide range

Trying to tune your car with the narrow bands is risky at best...if you want to play it safe, aim for the upper end of the spectrum listed above. I don't think anyone has come up with a direct correlation between mV and actual AFR since those sensors just are NOT accurate under WOT conditions.

920 mv if exhaust is cool and 860 if exhaust is hot, hard to tell were
its at, just a guess just shoot for 930 and be safe.........
