Because many manual transmission trucks got by with the C3.  Only those
trucks with "E" transmissions needed a newer generation ECM.  Note, I
think there are several years where a manual transmission wasn't offered
on all models/engines.  Hence, some years didn't use a C3 ECM.

I assume GM had a fully depreciated production line cheaply cranking out
old C3 generation TBI trucks ECMs.  As long as they could meet emissions
standards, there was no need to upgrade.
