Wide Band O2 Installation Questions
I've got the new PLX rear view mirror all wired in for a boost gauge and the OBD2 interface - I was going to hook up the wide band today and realized it wasn't as easy as I was thinking.
I'm running AP headers with pre and post-cat bungs. The post-cat bungs have spacers/deflectors of some sort. I assume this is for cars that care about post O2's. I also assume this will mess up my wide band reading. I put my stock post O2's back in there just so I wouldn't have to zip tie them somewhere.
So - two things. First, I was thinking that I really need a wide band for each header/bank? Do people normally run these into a collector or call the data off one bank good enough? Secondly, can I just buy another wide band sensor and replace both of my pre-cat O2's with the wideband's? Then route the signal to the ECU and my gauge via a splitter of some kind?
How have you guys got these things wired in?
