ECM ID

Personnally I haven't seen a 16------ used prior to 91.
But, that isn't to say they weren't.  If you have then that's
a new one.  There are some Body Control Modules used
starting also in this era (that are 16------).
  The little I played with them, I really grew to dislike them
almost instantly.  At the time I didn't have internet access,
and they just loved to throw codes.
  On one cop car TBI it looked for a MAP difference for
EGR apply.  It would set a code for the fuel pump 2
sec prime cycle, may have been for F/P v during crank.
Played marry hell with 4066's and voltage dividers, and
scr's for killing the codes.  Managed good MPG, and
was forgiving for getting the MPG, lackluster purpormance
thou.

a kid,  (well body permitting).  At least when making new
mistakes
