When you disconnect the factory O2 harness, the DME brain goes into a default mode (aka rich). After you connect the analog-out signal to the DME ECU, you should be back to more normal A/R settings. Try that.

Yes, that's exactly why I asked the question, how you hooked the two 02 sensors (stock and LM1) up. Unless you hook them BOTH up, your readings on the LM1 will be meaningless.

Glad you found something that may pinpoint to a problem, but I still recommend that you put the stock 02 sensor back, put an extra bung (in front of the cat.) for the LM1 and retest.
