differance

is there a differance between 94 and 95 computers?
and 96 and 97 ?

94 is an OBDI PCM with a 12 pin ALDL
95 is an OBDI PCM with a 16 pin ALDL
96 and 97 are OBDII PCMs with 16 pin ALDLs.

so i cant use a 94 computer in my 95?

Any 94-95 pcm from an LT1 car will work on your 95. Just be sure it has service # 16188051. It will need to be programed for your car.

Unless the pcm came from the same type car with the same options(gear ratio, transmission type, etc) it will need to be programed for your car.
