Thank you for your responses. You are right, there appears to be some interesting obstacles on this path...
As for working perfectly, I meant that it works on an electronic bench and on a engine with a simplified ecu (no OBD II).
Looks like I may need to go back to the drawing board...

Whether or not it will be more accurate than a stock O2 sensor... :dunno:

You'd also have to engineer a bandpass filter and/or voltage spike suppression circuit to prevent really bad things from happening to your ecu. Its a good idea overall in theory, but with some of the more powerful PEMS coming out, Wideband logging is already available and you can tune the fuel map right there without having to devise circuitry to fool the ecu. :thumbup:
