Kevin,
The 1988 and 1997 PCM's are totally different animals... You can't take the
binary from a 1997 PCM and run it in the 88 PCM.  What you need is the table
info for the computer you have so you can modify it (Try the chip from a 1988
Bonneville Supercharged if they made one or a park ave ultra). or put the PCM
and harness from the 1997 donor.
