The electrical interface to the ALDL connector is a bit different on
the '87 and older GM cars VS '88 and newer. Data rate on older cars is
lower and the ECM data line is connected to a different pin on the
ALDL connector.

You'll need a new ALDL to RS-232 adaptor and possibly an update to the
software. I'd check the software vendor's site for details.
