I want to make an emulator so i can pass inspection for my secondary o2 sensor.
I don't understand this chart.
Does anybody has any instructions.

 

its pretty self explanitory. there is a legend down below, the 2 pc boards are what you use to mount the resistor and capacitor. id assume it would only cost just a little more to get a real o2 sim though. take into consideration that this thing will be subjected to heat and moisture. although the home made sim may work, id recommend the real thing. check out jacobs electronics or ebay. hope this helps

 

stillen has one now as well they sell with the headder for the Spec V i know its nissan but it is an o2 emulator nontheless.

 

I need it to work only for an hour, just so i can pass inspection.
The 02 sensor at auto zone is 80 bucks.

 

Won't work because if you have a CEL already and you try to reset the ECU then the ECU goes into default values. It looks for speed checks, braking, and other variables. Until those are unlock the ECU will respond back to their computer stated it's code locked. If the 02 sim doesn't work(more than likely) then it will have a CEL again after xx miles. Best thing to do is buy a real 02 sim.
