Looking into getting a wideband o2 and im also hoping to log it. General consensus seems to agree that connecting to the unused EGR Temp pin on the ECU (pin 53 from what I can tell) and setting up the logger correctly will do it. Ok, easy.

But will the ECU start seeing that line an assume there is an egrt sensor connected? Or does it ignore it? Would that not mess with the tune or am I worrying too much.
