Wideband reading lean after free-air calibration
Hello,
I recalibrated my Innovate MTX-L wideband after a couple of DEs and my AFR numbers are now lean under boost.
Last calibration was at initial install almost a year ago and VE table on my MS2E has been dialed in.
Under full boost (80kpa) I was hitting my AFR target of 11.5 and now seeing values of around 13.
Has anyone else seen this before? Would appreciate any help.

There's always the possibility that it wasn't properly calibrated when new and now is. Try calibrating again. Make sure to remove it from the exhaust pipe when calibrating, you mustn't leave it in.

That's very possible but I'm hoping that's not the case since that means I've been running lean under boost this whole time. Yup, I removed it from the exhaust pipe when calibrating. I'll give it another try and see what happens. Thanks.
