Likely the PCM is part number 16147060: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?317-16147060-PCM-Information-85

Remote tuning is challenging, but possible with data logs attached to an email.

Perhaps the Getting Started with TunerPro RT video will be helpful. https://www.youtube.com/watch?v=rLRnRNapRN4 Although the video is not specific to a 1993 454 ss, the nuts and bolts about data logging are the same.
