I don't know if I missed something while reading through all of these pages, but what is the physical method for removing the rear o2 sensor. I saw that the link on the 1st post no longer works so I'm not sure if I can just unplug it or whether a resistor is required or not.

Not sure which links you are refering to that don't work. The only ones that don't work are the JoT links for ecu pins and the evo 8 pin removal link. If those are the ones you need then I'm not sure what you can do. There must be info out there somewhere on how to remove evo 8 pins and where to find the pins themselves, or you can use this guys method

For some reason after doing this ECU pin mod I have lost gas mileage - I used to get 17-18mpg and now I can barley get 15mpg! I am going to reverse everything tonight and hopefully my mileage recovers.

i have a 9 MR and tapped into the rear 02 sensor as well because I could not get an ecu pin. I have the correct MUT table 8409 value of and in the correct cell. It just logs 13-15 back and forth throughout the range. I logged with the guage at a constant 14.8 (car off,ignition in on position) and it does the same. Perhaps the white wire is not universally the same wire on all 9's. My option was that, or a red/yellow I think. I used the black wire as the ground. I tested with a voltmeter and got 2.3v at about 15 afr. What did I do wrong?

Ok, I tested the red/yellow wire and the blue wire and both gave me a static 10. So the white wire seems to have the right data, but it's just going in circles 13 14 15 and everywhere in between but no other numbers show. It does not correlate to the guage. Heeeeeelllppp. PleAse and thankyou Evo gods.

Any update on the final formula for a Zeitronix ZT-2 using the white wire. I already went through this whole thread and have no definitive answer. I have also been trying multiple formulas, some are way off/off by a point/or somewhat close. Thanks in advance!

Just out of curiosity, how come you're not using the digital signal?

I believe Jack of trades came up with a formula for the zeitronix analog signal but never posted it because he was using the digital signal? Don't quote me on that but if no one else replies you may be better of PMing him.

- Older version: The purple wire is the digital signal and the white wire is the analog signal.
- Newer version: The white wire is the digital signal.
This is of course if my memory serves me right. Check your manual/instructions though.
If using the digital signal then everything is much easier and you should be able to set it up using Mr. Fred's instructions (Disregard the grounding portion of the instructions with the digital signal, your ZT2 should already be grounded). Good luck and if there are any questions, ask.
