[QUOTE="Fred W, post: 1248174, member: 3828"] I don't think the PCIII disconnects the O2 signal for a couple of reasons. I think it has a pass through on the signals that it doesn't use, including that one. While the O2 sensor signal does pass through that cable connector (on both Generations), I recall that DynaJet specifically informed me to disconnect the O2 sensor. even though it isn't in the 1st Gen's installation instructions. When I did re-connect the O2 sensor on my 1st Gen as an experiment I'm fairly sure that it started surging again, though it was quite a while ago. Also, there is a "street legal" version of the PCIII that does require the O2 sensor to remain connected, but I suppose the wiring for that one could be different. It would be pretty easy to ring out those pins with an ohm meter and see if the signal gets passed thru [/QUOTE]
