Nah, dumb it is indeed. Doesn't remember a thing. Digifant and Digijet
live constantly in the present, looking at what the engine is doing
and adjusting what they can according to hard-coded data tables in
ROM. There are probably two or three things on timers, like initial
engine warm-up mode or bogus O2 input sense, but they represent a
"memory" of no more than a few minutes, max. Vanagon ECUs are pretty
crude by modern standards.
