Cool! It IS a computer. The injectors were pulse
width modulated.
Somewhere I have the manual for that thing. My mother had a '70 VW type
III
with that system and it ran great.
I suppose it is -- although the one being described (L-Jetronic) is an
analog
one comprised basically of a variable duty cycle oscillator. In many ways
it's
like an electronic version of K-Jetronic; all the injectors fire at once
with
no synchronization with the cam and duty cycle controlled by a set of
variable
resistors (one on the airflow sensor [which was _not_ a MAF]), one for
engine
temp and (only on some) one for ambient temp)
Motronic, which is a programmable digital engine management system, is more
than ten years old as well, although it's just now starting to manifest some
of the features that were designed into the original architecture back in
the
'80s...
