Don't know of anyone with the same car! ;-)

Maybe strange, but I'd check it in the first place. Have you talked to
someone with the same car to ask if he noticed similar behavior?

That would be a very odd fuel pressure issue, to have a problem for a
moment, and then not have it again if you continue driving!

Yes, that would be logical. Didn't matter in the present case, as codes
were pairs of digits, each enumerating a condition, not together as an
actual numerical quantity. As I recall, the first digit was subsystem
(ECU, ABS, etc..), second identifies what (oxygen sensor, ignition,
etc..). If one system had more than 9 error codes, dunno... they might've
just keep blinking it? Of course, most systems had only a few codes each,
so most of the numbers that could be expressed weren't needed.

Are you sure that it's a firmware feature and not just fuel pressure
issue?

Suzuki Hayabusa (a motorcycle) has two levels of "check engine" (actually
"FI") importance. When the "FI" LED lights steady, it's a minor problem
and you can ride, ECU just substituted the signal from a failed sensor
with a reasonable constant. When it flashes, it's fatal and engine is
stopped.

Strange, I would code "0" as ten pulses.

That sounds like a group cell death in the auditory ganglion and
subsequent re-routing. Rather uncommon but not unheard of (incidental
pun acknowledged). The nervous system is a marvelous thing.
