Hey guys...
While I am still puttering around with EFI Live and dragging my feet with buying the streams, my day to day work is with HPTuners.
I had a vette today that was previously street tuned (no wideband) with EFI Live. Besides being 10.0:1 (richer; that's the wideband's floor) until 4500 where it moved to about 11.0:1 at WOT, it ran and drove very well.
I had the owner drive me around the block beforehand because I wanted a scan. B2S1 was at 445-447mV the whole time (yes unhooked or dead) and not only did the car NOT code for it, B2 was TRIMMING in a fashion that so closely followed B1, it looks like the data was actually coming from the B1 sensor.
Is this really a "thing" ?
