Bill;
I looked at that last night and it looks to me like the cats have been removed and those are resonators.:confused:

Yea it looks like test pipes to me but there are some cat-like things just behind that and mufflers way at the back. Doesn't really matter as there is nothing ahead of all four of the sensors in the pic.
I got ya, could be and it doesn't really matter, but resonators are usually separated from the mufflers just like that and I couldn't see any rear 02 bungs or sensors.

i am trying to hook up a wide band to my mpvi unit, i have the zd2 controller any advice there?
Hey all, I will be doing this very project next Monday. Thought I might spare myself a hassle by asking what the pin numbers are for the EGR connection and narrowband o2 on the 2000 WS6 PCM. I plan to cut and splice in close to the PCM so it should even be good that the car already has wires in the EGR hole, and it just seems to make sense for removal to make the cut closer to the PCM for the narrowband o2 sim because it's a drier area and the wire and tape won't look as redneck there. :)
Just read the OP's PCM was introduced in the F-Bodies in 2001 somewhere.
The '04 GTO has 2 sets of cats..... main cats up front, then secondary cats. The post cat 02's are shown in the pics. GM lists the rear ones as cats, even though some people claim they are not. My 04 still has all 4 (waiting on cat-less mids to go with my shorties, or to finish my turbo setup.... which ever comes first).
From the factory my car had 2 cats just after the manifolds and only 2 pre cat o2 sensors. When i installed the turbos i removed the stock cats and got a custom exhaust made up with a couple of bungs on each bank so i could move my wideband around.
All sensors should go after the turbo and BEFORE the cats. the round things just after the narrow band sensors are after market cats, the only thing in front of all the sensors in the turbo.
i was running 2 wideband sensors and Open Loop when i took that pic. The front 2 sensors on each side are for the widebands and the rear 2 are where the stock narrowbands go (the left side one is missing and i have a nut plugging the hole - OL)
Hope this clears things up.
I am working on setting up the PID's, and am having a hard time reading the function string. I have tried to open the attached file, but with no luck.
I am setting up my SM-AFR GEN 4 Unit in a C5 Z06.
Thanks in advance!
old post, but great write up.
i have mine set up, but only want to hook it up to HP Tuners on the green plug on the side?
How do i do this to get it to read into HP?
I answered your other post... not complicated though. Just connect the 0-5V wideband output to input 1 on the interface.
Follow how to's in this thread to walk you through making the wideband readings display:
