European ECMs

[Bruce Plecan]

Does anyone out there know what kind of numbering system GM
uses for the  european ecms.  I'm trying to figure out if they use
a version of the 1227730, 1227165, 1227749, or 1227808.
These were used from about 1986-1992 in the USA/AUS..
All but the 1227165 were always 8192, the 165 could be either
160 or 8192.  
The 730 had 3 connectors on the side of the ecm, and the others
2 connectors on the end.
If this is covered in the archives, would someone tell me where.
Cheers
Bruce    Stuff hit the fan this morning.  Staffers were using their 
              spare Hats as construction zone obstacles, and racing
              the EV thru the kitchen.
