ECM and Sensor readout?

[rms29 at cornell.edu]

I've got a friend tht does a lot of DSM tuning, and he has a connector
that allows him to see ECM readouts on a palm pilot, as well as do
data-logging.  Pretty cool, can drive around and see when the old lifters
make enough noise to trip the knock sensor and retard the timing.  Is
there any such gismo for older audi ECM's?  I've got an '87 5kqt and
wouldn't mind paying attention to such things either through a laptop or
palm pilot when I finally get around to starting modifications on it.....
