plx units are quite good and flexible, very good base for your project. I've got quite a few customers using their system with great results:)

Hi,
I think he picked up on the Lean Bank by Temperature differences from left to right. The difference was a retarded cam. The other reason not to put it before the turbo is Heat Sink skewing the readings.

Wish I knew more, sorry I don't.

Pre turbo, there can be as much as 2x the boost pressure.

I think you can read about the O2 placement on the Innovate site.

Thanks, reading up!

Hi,
It's pretty simple equaton here. The sensor should be 8" from the turbo and downstream. You probaly will find it hard to get 8" from the turbo. I put mine between the muffler body and the Turbo flange after screwing up twice and putting it in the coillector ahead of the Turbo. If you put it pre turbo and a professional tells you the Heat soak will make it read wrong, it will worry you till you move it. That is, if you are tuning with it. It read about 1 point rich before the collector as opposed to after it for me. In another words, the car was leaner than my AFR was telling me.
