How complicated would this sort of thingy be to construct?

I think you just need a 600mv constant voltage power supply while the car is running hooked to the O2 leads, and a resistor to make the car think the heaters are working. For me that would be super complicated to build, for P-wave, well if he's reading this, he's already designed it.
