Dude, the display is like $40 more, if its that big of a deal just spend the extra dough and get one.

Do you have a part number for the Bosch O2? You can use any O2 right?

You have to use the Bosch 17053 Oxygen Sensor. Cheapest place is NAPA to buy it. About $52

This WB is 5-wire right? And does the connector matter? Looking at pics, they all look different from the one you have on yours. Or the same model is the same across the board?

Yea there is 5 wires going to the sensor. It has 6 wires going from the JAW to the connector. They should all have the same plug on them. As long as you get that sensor number it should be right.

Hey man. Well I got a few questions. I have yet to get it all hooked up because I'm waiting for my serial to usb cord to come in but anyways.

After I throw it in and hook it all up....What do I do from there? I'm just confused as to what all i need to do to get it up and running. Thanks for any help in advance.

Hook it up inside first. Hook it up to your laptop and do a bench test kinda thing. Hook up the sensor to. You pretty much just follow the instructions he gives you. You load the software into the JAW. Then you calibrate it and test it with a butane lighter. Release the gas right into the tip of the sensor and the AF ratio should go down to 10 or so. This will let you know your sensor is working. Save the calibration and install it in the car.

Just went outside and hooked up my JAW today just to check everything out and see how it is working. Sensor seemed to be dead on with the a/f ratio. Im deffinately going to be ordering a display for mine soon.

The thing I like most about this system is how you can change how many samples/sec the logger records. I log 100 samples/sec when I am tuning the car, which gives a very accurate graph.

But why does changing it really matter? Obviously you want it to sample more for accuracy, and I'm thinking that slower computers may not be able to handle the higher sampling rate, but I can't see there being THAT much data coming in to really bog down a computer.

I dont think most computers will have any problems with it. It doesn't seem to have any effect on mine, and Im usually logging Emanage also and making adjustments.

I finally remembered my question. Since I have a cat, is it not recommended to put the WBO2 there? Does the cat throw off the numbers?

SilvrEclipse · #27 04-02-2008, 08:05 PM

I think I remember someone saying that once. Im not sure how much the cat will effect the readings. You need to keep your rear o2 in anyways since you have emisions. Just have a bung welded into the downpipe when you get your EGT bung in.

Sounds like a plan. Looks like I'm going to take the header off one day soon and get the EGT in the runner and then another O2 next to the first O2. I want it to be pretty accurate and I think the cat is going to throw it off some. I hate emissions

I dont know about you silly 420a guys, but I'm 95% sure the downstream o2 sensor on 2g 4g63's is just there to see if the cat is working or not. IIRC if the o2 signal is different from the first one (meaning the cat is doing its job) its happy, but when the rear o2 signal is the same as the front that means the cat isnt working and it throws a CEL. Other than that CEL it does nothing.

david-b · #30 04-03-2008, 01:03 PM

It's the same here, but maybe the ECU compensates that the cat is there.

Like so much voltage is in the upstream, but less in the downstream because of the cat. Maybe the ECU is programmed to adjust that so it looks even, even though it's really not. Make sense?

Plus, I'd rather not have a CEL on while tuning and shit especially from something as stupid as the rear O2.
