This DIY will help you if you have an SES because you installed test pipes or something similar.
This write up is different than the many other o2 simulator write ups, because this one allows the user to COMPLETELY remove their secondary o2 sensors.

Can i build o2 sensor simulator without leds (1.7v@20mA)
If I can, then how:
1. what components needs instead leds;
2. have any schematic?

Here is my design. The newest design is the smallest one. Just a note, I deleted one led and replaced it with a 10k ohm resistor. It will reach 1 volt when the input is 16 volts. At 14.6 it's at .8 volts.
Is it better to make it turn on and off every second or keep it how it is?

What would happen of you run the Simulator on the pre-cats if your running a Piggyback computer? I'm thinking nothing because ur not using the stock O2's anyway. I would assume that this Simulator Simulates voltage, if so would you happen to know how much voltage equals air/fuel ratio of 13 or even 14?

And to answer your other question, no, this simulator does not simulate voltage. It simulates duty cycle and pulse frequency.

Am I understand everything clear: I need to find two wires (74 and 75), cut them and side which came to my ecu connect with circus output, leaving another side of this wire, yes?
If this is clear, then can i connect this emulator straight to o2 sensors (connect to this two wires just in another place)? Because i dont want to damage wires straight near ecu, i think its easier, if something gone wrong, just change o2 sensors, not wires through all car

Hey guys I wanted to chime in and say I was getting the typical codes after installing catless pipes. I built this circuit and it got rid of the codes but in my case I also had the p1283 code and this resolved that as well. since that code wasn’t listed in the original post I thought I would share my results, I have an 05 base and now at a little over 700 miles after install and everything is running fine with no codes
