Diacom/Serial Data

[Bruce Plecan]

Well more confusion at CSH,HQ.  I had the inpression that there
were two serial links, the 160, and the high speed.  But, on the
diacom it is very specific on how it links.  Thought there would 
be just two variants.  But there is more two it than that.  Has 
anyone worked out any universal "most info. available" VINs
Using the MPSI on one ecm I also got a grams/second reading 
on a MAP application, but that is also one one of the gm mapto
maf conversions.  
  Are injector pulse widths only on port configurations?.
TIA
Bruce
