I'm interested in what I'll learn too. ;)

It's definitely a flash chip.

You could always talk to Steve at TTS ( http://www.ttspowersystems.com ) -
his Powerloader would be able to load your PCM with a program, and he'd be
able to set it up for any mods you might have. Or Ed Wright at
http://www.fastchip.com is able to reprogram LS1 OBDII PCMs. He does a ton
of 'em. No owner-tweaking utilities available - *yet*. :)
