Hey can anyone do a write up on the installation of the Zeitronix wideband 02 system? specifically the boost sensor setup would be awesome so I could get an idea of what the HELL i'm doing wrong

 

I know it's old, but bump! I would like to know also.

EDIT: Nevermind...

 

Need some help as well.
Anyone with advise on boost install of Zeitronix?

 

Do a search. It's there.

 

Crazy there is no How to....I am going to install this weekend and will take lots of pictures ....Scott (TTP) is there a nicely documented How To that is specific for the EVO ?

 

i'm going to need a how to as well =) thanx to any1 who will take their time and help lots of people out

 

me too.

here's what i have found so far:

We include a hose barb with the boost sensor. Connect a vacuum line into the hose barb and connect to the line from the intake manifold using a T just like you would install a boost gauge. A fuel pressure regulator line works fine. Just make sure you use a quality vacuum line which won't brake get punctured or leak. A leak and a falls pressure information to the fuel pressure regulator will result in lean mixture under boost!
Connect the Boost Sensor wires to the Zt-2 as follows:
Zt-2-------------Boost Sensor
Orange--------Green
Yellow----------Red
Brown----------Black

Done. Enjoy the most accurate boost gauge.

Well I have started the install by removing the downpipe and welding an 02 bung right before the rear flange. I plan on routing the wires through the grommet right above the new bung and into the cabin.

I will have pictures and details in a How To coming shortly.

The question I have is how folks get the wire into the cabin (through the grommet hole) as the plastic plug (rectangular) appears too big to go through any of the holes??? Does the O2 sensor wire disconnect where there are 2 zip ties and a little plastic cylindrical piece?

Basically where I am installing the O2 is right below the grommet so I dont want excess wire hanging near the driveshaft. Thanks

 

You may either put the sensor itself through the hole OR leave the weatherproof connector outside of the grommet altogether.

 

When you weld a new bung make sure to account for exhaust piping movement to allow additional clearance from the O2 sensor to the surroundings. Keep the O2 wires away from hot exhaust components. Keep most of the O2 harness inside the cabin and whatever is under the car zip tied nicely away from any hot and rotating parts. The RJ-45 connector is one of the smallest multi pin connectors available. It really does not get smaller than that. Usually you can tape the RJ45 into a piece of wire (a coat hanger) to fish it through small openings. Do not grab the RJ45 connector with needle nose pliers as you probably will damage it.

Hope this helps

Hey Mr Z -- It is not the RJ-45 connector that is the problem it is the large connector that connects to the cable with the RJ45 -- it appears to be larger than a quarter.

In the middle of that cable there is a cylindrical plastic piece with zip ties on either side (the plastic piece appears to be a connector). Is this plastic piece a connector and if so can I just unplug it to run the small wires through the floor (grommet) and then reconnect?

I have the O2 sensor mounted vertically (sensor down) and want the wires to be completely secured within the cabin (so there will be no extra near the exhaust or drivetrain). Thanks

 

The O2 harness has two connectors, one on each end. A small RJ45 on one end and larger O2 sensor connector on the other end. There are no other connectors in between.
If you want to keep the O2 connector inside the cabin then fish the O2 sensor through the grommet hole.
You can also push the RJ45 through the hole from a bottom of the car, push the entire 10 ft of the O2 harness through the hole and leave the O2 connector under the car. There will be about 2 ft of O2 wires from the sensor side to zip and secure under the car. However the less wires under the car the better.

question about the WB wire: Will a single core wire carrying 12VDC/~10A running parallel to the WB line induce a voltage and mess up the signal?

 

No it's not a concern.
