As far as I can tell, the ECU is not controlling the distributor at all. If I change the value in the table where it's idling, there is no change where the indicator is on the balancer. I swapped over the SPOUT and PIP wires to where they specified in the instructions. I don't think the car would even run if either of these weren't hooked up properly. Could this be a symptom of a bad PIP sensor or TFI module? I don't think it is, but it's worth asking. I do know when TFIs go bad, the symptoms are they mostly quit working when they get hot. Still leaning towards something not set correctly in the software.
