The PCM in the 93 and up fbod/Corvette cars (OBD II ?) is flashable and requires tuning software to re-write the calibration rather than physically replacing the EPROM chip in the PCM.
The first year for the LS1 was 1997 in the C5 (and then 1998 in the fbods), so the LS1 would always have had a flashable EPROM vs. the old 'replace the chip in the PCM' style.
...and yeah, people get uptight around here when you mention 'chipping' an LS1 haha.
