Correct. The NBO2's will report back to the PCM that there is a lean condition and then the PCM will increase fuel trims to richen up the mixture. In essence, the car should "learn" at cruise and transfer additional fueling requirements to WOT. Those who are running in open loop will need to adjust their tune manually.
What happens if we use 14.07 for stoich?
In {B3601} can we use 14.07 and be Ok with the trims or is it the EQ that is the deal here? There is not one Gas station I am aware of in close range of were I live that sells Gas without 10% ethanol.

What about a WBO2
Hey SSpdDmon,
I am not trying to be difficult but I cant seem to get my brain around this.
The NBO2 sensor will detect a lean condition because there is one, that I get. but why not just use the 14.07 in the 97-04 PCMs B3601. That would mean that 14.07 is stoich for those PCms then if that is the fuel ie. 10% ethanol? Right? or wrong? Help anyone, help!
