Widebands really are lambda sensors, that include simple math to covert it to the AFR scale you "commonly" need.
For pure gasoline, it's Lambda * 14.7
For normal e10 gasoline, it's Lamdba * 14.36
(and so on)
So, 1.0 Lambda is always the perfect stoichiometric balance of air to whatever-fuel-you-use.
From what I see in their directions, Lambda min is .68 and max is 1.36. (And .68 * 14.7 = 9.9.96, 1.36 * 14.7 = 19.992).
So, if you leave the sensor in free air for an hour (probably less), it should peg at (in your case) 1.36 lambda (ultra lean)
In the narrow band (something around 14:1 to 15:1), the factory O2 sensors should be close to your wideband, if it's configured correctly).
Are you trying to configure the analog output of the wideband as an input into HP Tuners for data logging?
