I found this one:

zx2racing mil eliminator

From what I can see we must put a capacitor between the white and blue wire because our heater wires are the black one instead of the white on this diagram.

I don't know to much about electronics but if I remember well, the use of a capacitor is to store electrons. I don't understand why we want to use a capacitor here.

I also found on a Subaru board that a guy try with different Ohm resistor and finaly get it work with a 2.2K resistor.

Subaru i-club link about o2 sensor

First I think I'll try with a 2.2k Ohm resistor.

What do you think, is there an electronic expert here who can help us?

From what I've read about O2 sensors, I can explain it this way. Your O2 sensor is always getting different O2 reading. They are always fluctuating. In order to get that fluctuation, you need varying signals being sent to the ECU. If you just have a resistor in there you will only have a weaker constant signal going to the ECU. A capicitor can be explained using this analogy. A capacitor is like a glass of water. You can hold it under a faucet and it will start filling up, then it will overflow. A capicitor fills up with a charge then when it reaches it's peak holding capicity, it will discharge all that electricity. This gives you the varying signals the ECU needs.

My question is this, which wire is the power wire and which wire is the wire going to the ECU? I'll try mine again if I can get this info.

I have talk to the guy who wrote the webpage about the modification on zx2racing, and he said exactly what you wrote, tha capacitor is used to get the fluctuation. So I will try with the capacitor as soon as I can get some spare time.

The blue wire is the o2 output that goes to the ECU. the 2 black wires are used for the heater and the white wire (ground) is the one we must use to install the capacitor with the blue wire.

I'll do the test and get back with the result in a couple of days!

 

[big_ben]

So the white wire is the ground? I'm used to the black wire being the ground. I probably have it backwards then. The only thing that sucks is that it takes a few days for the O2 sensor to come back on to see if it works.

 

[big_ben]

I'm confused. So which wire should the capacitor be on? White or blue?

 

[Stou]

IF you look at this diagram:

Our blue wire replace the gray wire and our white wire, replace the black wire.

The resistor must be installed on the blue wire and the capacitor, between the blue and the white wire, after the resistor and before the connector.

I will test it next weekend.

Here's what I tried:

I add the capacitor with the 1 Meg Ohm resistor. This setup was good for about 1 1/2 hour of riding and I got a CEL.

I add another 1 Meg Ohm to the previous setup and it didn't work. I got a CEL after 10 minutes. Too much resistor. Maybe I need to reduce the resistor, like I wrote earlier, a Subaru guy got it work with a 2.2k resistor....

Anybody got an idea?
