Here you will find listed all the BCC's I've come across programming the lt1 pcm's.  The LT1 computers can be programmed for whatever application you have, iron head, aluminum head, 4.3L or 5.7L.  Where using these codes might come in handy, is if you have a 95 iron headed motor, they will have two knock sensor on the block.  So if you need a PCM, you should find one orignaly from an iron headed motor, so you have the correct knock sensor module.  The knock sensor module is located inside the pcm, under the cover with two screws.  This module MUST match the knock sensors you are using.

KNOCK SENSORS: Installed in engine block

1993 to 1997 Camaro and Firebird used 1 knock sensor.  1993 to 1995 sensors different then 1996-97.

1994-1995 B-Body (Caprice, Impala, Roadmaster, Fleetwood) used 2 knock sensors. 1994-95 sensors different then 1996.

 

KNOCK SENSOR MODULE: Located inside the PCM, under the cover with two screws.  8 digit # on top of module. (this info I have confirmed in PCM's sent to me, but please double check if you can, if you find an error, please let me know.)
