According to a quick skim of my Bentley, as per memory, the 4 cyl (USA) 
id Motronic, not CIS.  IE, completely incompatible.

Every CIS-E3 car I've cut into has two control units - one for fuel, one

for ignition.  In fact, my 90Q came to me with an 87.5 ign. computer 
installed, that I sold the local tech to get it running again.  Fuel in 
one place, ignition buried in the right kick panel where windshield 
leaks will kill it...

In short - as far as USA models go - the 4 cyl is Motronic and 
completely incompatible with the 5 cyl CIS-E3 system.

As far as the ROW is concerned, well, we don't know for sure... they 
won't tell us on the news, what's happening out there....
