[QUOTE="Gitbox, post: 1247186, member: 86950"] The Power Commander III USB installation manual does not mention disconnecting the O2 sensor. In fact, it doesn't mention the O2 sensor at all. I have read that it needs to be disconnected for the PC III to work correctly, but would that not generate an error condition? The ECU has codes for improper O2 sensor operation and since the PC III goes between the ECU and the injectors and not in line with the O2 sensor, how is it that no error codes are generated with it disconnected? I tried asking PC III tech support, but they did not even know the FJR has an O2 sensor, so they were no help at all. [/QUOTE]
