Legally, the purpose is for eliminate the codes. (as a peace of mind in-case other codes are present) but, I've been told that others who have used it(for example, from link I provided earlier) to try and pass emissions succeeded.

I'm curious also.

This method I found out was a hit or miss, as the spark plug defouler method (taking the 02 sensor out of the exhaust flow) was.

A more complex circuit would need to be built so the ECU does not flag the consistent voltage. This would call for a oscillating signal generator (witch I currently use), that would oscillate the voltage signal from .11v to .81v greatly mimicking what a typical working post-cat 02 sensor should be doing, and in-turn, keeping the ECU happy.
alright, my bad... I didn't read this till now. I was under the assumption you were running a single voltage that other O2 sims out there do. What you're doing seems to be correct. My apologies

Might have to pick this up, I don't think my normal o2 sim takes care of the heater code.

Thanks
Could you post this for us to see? I would like to know more about this product to have any interest in buying it...

For the heater emulation, its just a in-line resistor. Are you just in need of simulating the heater function?

Note that I will probably not be making these much longer, as I have gotten busy with other things, since I first posted about this.
