factory sensors are wideband. I am reading them through obd2 using dashcommand and when comparing the readings to my innovate mtx-l they are very similar if not the same. I keep the actual gauge on the glove box just for peace of mind but I mostly go by the stock sensors.

What happened to the JUN cams?

From what I understand the OEM sensors are widebands, but not to the same tolerances as an aftermarket wideband. The OEM widebands do not read accurate below 12:1 on the a/f scale. This makes sense because an N/A car should never run richer than that.

The donor car I just built the ST kit for has a significant discrepancy between the LC-1 and the OEM O2 sensors. I would never rely on the OEM sensors for tuning a turbo/supercharged Z. This was confirmed by one of the most respected pro tuners in this Z community over the phone a couple of weeks ago.

Correct. Hence why I have an mtx-l as well.
