Ecm/pcm
The 93 has an Engine Control Module (ECM). When they added the electronic A4 controls and M6 skip shift in 1994, they changed the designation to Powertrain Controls Module (PCM).
Your 93 does not have both an ECM and a PCM if that's what you are thinking. Or maybe you just meant "ECM and EPROM"?
