Where do you place them?


both in the downpipe?

 

Mine is in my HF manifold but i believe this could be the cause of some random Code 1's I've been getting. I could be wrong though but I'd suggest in the downpipe

 

Them...i only have one :P

I had mine on the first bend in the DP about 5-6 inches after the turbo outlet...Hmm...for the second one you could mount it right next tt like the B16 mani i have here or infron of the cat like OBD1... I'm not sure about that

 

yeah, id prefer to keep both if possible.....

 

Really doesn't make a difference once a turbo goes on. Since the b16 ecu's require 2 o2 signals, I just tapped the second o2 into the primary o2 sensor and ran that. No problems at all with it so far, and I'd place the sensor about 6" down on the downpipe.

 

When you tap...


do you mean cut the wries going to the second o2 and just splice them into the wires on the first o2?

Cheers for the help btw not long now...

 

Exactly. I did it at the ecu harness so it was nice and neat. Should only be one wire btw. Pin c8 is your secondary o2 sensor...spile it to wire c16 for your primary o2.
