The gauge reads leans. I have calibrated it a couple of times per the procedure but still getting lean readings. The car is stock so I should be reading 14.xx
I have it mounted a few inches away from bank 1 narrowband o2.
Thoughts?

That is the commanded AFR on a stock tune.

14.7 is stoich
WB reads 18 to 19ish
I tested the WB outside the exhaust with some fuel soaked rag and it swang from 22.4 to 7.5, so the sensor works; but when in bung reads high. Perhaps ethanol content in the fuel is throwing it off?

As stated above, the ECU is commanding an 18-19 AFR when at idle. It's not going to be 14.7.

That doesn't sound right; the reason I say that is I am logging commanded AFR with Hptuners and showing commanded is 14.68.

What are your STFT?

0 at idle, within -/+ 3% cruising.
I suspect the WB is bad. Never had issues with PLX on my other cars. Tried to save $30 bux and get an innovate. Going to get another bosch sensor and see if that could be it. If not, going with a PLX.

Have you talked to Innovate? I've got an LC2 and it works like a charm. No issues from install to operation.

Phone just rings when I call them. I think sensor is the problem.

Amazon has the Bosch replacement sensor for a pretty decent price. I had to replace mine on my lc2 it was acting pretty wonky.
