FWIW, the EEPROM ECM's were only used on 94-97 (LT1's...LS1's are a
different beast...), and the 94-95 were OBDI and the 96-97 were OBDII. As I
am sure you know, the LT1 was first used in 92 in the Vette's and the 92-93
used a removable PROM carrier, similiar to the previous generation ECM's.
Finally, the electronically controlled transmissions appeared in 94 as well,
so I assume the 94+ auto flash was significantly different than the 6speed
flash. Perhaps it would make more sense to disassemble a 6speed flash,
interpret it, and then go ahead with an auto?

TTYL!
