I was using the terms in the most strictly logical sense.

That does change the sample enough for me. If this information was shared here, I missed it or forgot it or something. It would be of interest to know what results if ECUs are swapped between the '92 and '94.

More directly then, it might be that your connector doesn't interface well with the earlier ECUs.

Yes, but until your connector can be excluded.... What haunts me is that AFAIK, the Subaru Select Monitor doesn't have any problems with the earlier models. Someone here must have one and will perhaps comment on this.
It could be something simple like different signal voltages.
