HOTWIRE PLUS 8s
(3.9s = UK & Europe 1991-2000 or from1990-1996 for overseas Plus 8s)
There are more Hotwire Plus 8s that have been made than any other fueling type, EFI or carbs. Though they are more sophisticated than the Flapper models they are happily a far cry
 from the later GEMS and, luckily, still very approachable by the home garagiste
with some money. Few if any problems from the Factory. Diagnosis became easier with hand-held code readers. Sadly, the  system was the first to come under regulatory emissions pressure and there are ECU variations with the Morgan version having Morgan-specific features. Some
 parts have become difficult to source (email me)
.but suppliers and hardware and software repair is still available. It is simply getting more costly and harder find.
