BTW  this list interestingly talks more about TURBO than normally aspirated
applications..  Probably because the components, senders and computers are
interchangeable..

The 2 boxes are identical... 16196390 is the service replacement part
number... the BRZY and BXNS are the calibrations that came from the factory
in each box.  the 16229189 BRZY and 16244899 BXNS are the part numbers of
the box with the CAL.
