That's interesting about unplugging the rear O2 sensors... IIRC they're only there to check that the cats are working properly. If one is running catless headers, I would assume that the appropriate tune would essentially negate those sensors' function. Then again, I'm no tuner and I have no idea exactly what the sensors or tune really do in entirety.
hassmaschine is a genius when it comes to how these DME's work so I'm gonna try to bring him in here for a little insight.  Maybe we can get Bob@BPC or Phil@BPC to chime in, too...  |
You should call them, I've had good luck on the phone with them.
