I have some guestions about the two O2 sensors on the first B16's. I have looked to see what to do with them if I want them hooked up correctly.
Let me get this right. They are both actually primaries. One is for the #1 & #4 cylinder's and the other is for the #2 & #3 cylinder's. Is this right?
The pins are C16 & C8 Correct? (PWO & PR3 ECU's)
OK now I have heard that having them both hooked up correctly, will actually make it run too lean. Now the setup I have is an LSVTEC 11.5-11.7 comp, on GSR cams. Running on an B16 OBD-0 ECU ( probly not the greatest idea)
As of right now there is only one O2 hooked up. I was planning on hooking both up to the correct pins and seeing where the Air/fuel is on a Dyno.
I know this is an old dilema with the majority, but I need to get this taken care of and do it the right way......Even if I skip the OBD-0 crap and go to OBD-1. Im in Ohio, if someone can help me or at least steer me in the right direction it would be very helpful...

 

Recipe for disaster man. That setup with that ecu stock. Tune it on BRE or something if you want to stay preOBD. Or get a harness and convert to OBD1. Couple good websites for harnesses and ecus.

Is it a total disaster no matter what I do with the O2 sensors cuz, im useing a B16 ECU? Or will it be a disaster if I use both O2's??? Does BRE have a tuning limit cuz, its OBD-0? Please explain BRE. Who can tune useing BRE???? THANKS
