Are you sure the O2 bungs shown in the pic above is not for the rear O2? I am going to guess that it is for the rear O2 not the WB.

I emailed berk and this is what they said

"The location is much easier to reach than having it up top. It's primarily designed for the casual user who will use them for dyno runs. The more serious car builder will not have any cats. We don't have any on our S2000 or MR2 track cars.

If you are tuning using our provided port, then just keep in mind that it will see a consistent .2-.3 leaner after the cat vs. before. If you are using the ceramics then they will be another .1 leaner."

Sure - here's a Cipher log I ran while we were tuning my Orisis reflash. Check out Bank 2 AFR's compared to Bank 1. Other than that, I dunno, it's pretty much common knowlege for the VQDE...

I know the HKS Knock Amp also functions as an O2 sensor, in addition to its knock-detection functionality, and I know that Philthy has this setup in his G35, which is something I'm curious about.

Thanks for sharing. Thats useful info. So when Tuning, I will remember to tune using the driver side wideband to avoid leaving it too lean.
Great info. I appreciate the datalog. Thanks gothchick.
