Good question as to what the list shows.
My experience is that LH 2.4 swaps are pretty forgiving. After the ECU in my '89 died (and before I got a '90 T ECU), I ran one from a '90 NA. It worked decently but probably ran a little lean up at high RPMs.
I think that most of the Bosch tweaks between '89 and '90 are in the EPROM (and probably some components that were more robust than the '89 had.) If you have an LH 2.4 from an '89 NA in stock, it's worthwhile to swap in the EPROM from the failed '93 ECU.
Depending on the failure mode of your '93, it might just be the transistor for the fuel pump has failed. That's an easy replacement.
