Unless Innovate is willing to provide a chart that correlates sensor output voltage to your gauge readings, I can't say whether or not your gauge is reading inaccurately. With ECMlink, you always know what the sensor output, and what AFR that directly correlates to. I can post up multiple logs from multiple cars that look identical to your LC-1 voltage and AFRs. That indicates to me that ECMlink is probably right...Either that, or everyone else's AFRs are jacked too, which I find highly unlikely.
In addition, I'm going to assume someone at ECMlink did the math on the chart of WB switch points. You should think of your switch point as a constant. Using the LC-1 switch point as an example: no matter what, at 2.44v ECMlink will read stoich. When ECMlink sees any voltage reading below 2.44 it will indicate lean, and anything above it will indicate rich. ECMlink only knows that 2.44v is stoich. So, if for some reason 2.44v is not stoich, your WB readings will be off of course. However, based on the WB readings in your log and other's I've seen, I find that's unlikely.
The difference in concentration between oxygen molecules in the exhaust gas and ambient air determines the voltage the sensor produces. This is why your sensor needs to be calibrated. The ambient air at my house in Maryland and the ambient air at your crib in Oregon are not created equal. If your sensor was miscalibrated, that could also cause a variation in your readings. But, again, based on your log I don't believe this is the case.
Here's the bottom line; there's only one way to verify your WB is reading correctly, and that's to check it against another known good WB. In absence of that, I'd trust what ECMlink says, and what other logs can verify. In addition, I feel like someone would have noticed by now if ECMlink were reading incorrectly.
IF you decide you want to tweak the sensor, you'll need to modify the switch point under the NBO2 sim tab. Just keep in mind, it will be a guess and check process. Tweaking it too far one way or the other could have some pretty harsh consequences. Maybe Innovate could verify what the switch point of the sensor is.
Cliff's Notes for TLDR:
1. ECMlink says the LC-1 WB switch point is 2.44v, which I believe is accurate (stoich)
2. Innovate says their gauge is correct, but none of us have numbers/info/data to say one way or another without just taking their word for it.
3. Multiple logs I've seen show numbers similar to yours, confirming either your WB is reading true, or multiple vehicles have the same issue.
4. Calibrate your sensor to avoid inaccurate readings.
5. If you want to modify your switch point do it under the NBO2 sim tab, but be cautious since screwing it up could cost you a motor.
6. The only true way to verify your WB is with another known good WB.
