So why the discrepancy between lambda and o2 v. ?>>
I misread the meaning of voltage! Thought high voltage = lean. Actually....the opposite! One day I'll get it right!
So if the block 217 reading is correct....this car's AFR could in fact be spot on!!! That is after the fuel trim has had time to adapt.
The gauges will give me easier monitoring and some more toys to play with! : )

[does google search since can't remember] - 0.465V is about 1 lambda :D
The lambda curve is pretty steep with respect to voltage. So yes, 0.82 means rich. 0.65 is probably closer to about 14:1 or 13.8:1, again because it's a steep curve. It oscillates though as it doesn't generate a DC signal.<ul><li><a href="http://apps.bosch.com.au/motorsport/downloads/techtip0103.pdf">per the intarweb</a></li></ul>

Which is why Conventional A/F gauges...>>
are simple 0-1 volt meters. Wideband is a different animal and registers 0-5 volts for much more resolution in conjunction with a wideband sensor...

But the dancing lights look cool :D Maybe why most A/F makes don't even bother putting numbers but
just red/yellow/green lights. I'd sure like to get widebands for the A4 and TT, but wow on $$.
