Lambda? If you mean wideband oxygen sensor, then no. This is the second brand new sensor. Same issue.

I bought another BRAND NEW primary oxygen sensor and it did the same thing (I'm using Denso). And yes, when I went to the dyno, the tuner had his own wideband oxygen sensor (Innovate) and it read perfectly as we proceeded to tune the car. This leads me to believe there is a wiring issue of some kind.
