Gee, interesting that someone would ask about that engine.  I just spent
many hours trying to find a problem with one.  A friend is engine
swapping a 96 motor using a 93 ECM and chip (last year for a
stickshift).  We are having a problem with the VSS.

91 through 93 is a batch fire system using a variation of the 1227727
ECM, perhaps sharing code with the 3.1.  94 and 95 are SFI using an ECM
similar to (or same as) the early '90's 3.8 SFI ECM.  96 has a flash
programmable OBDII ECM.  If you manage to dump the flash of your '96 I'd
be interested in a copy.
