I picked up a used ECM the other day and it came with 5 older chips. According to the seller, one is a street chip (red label reads "super chip") for stock turbo, injectors. One for 36 lb inj and a TE-51. The other three are a mystery.

Two have alpha-numeric codes on the underside - are these related to the program within?

One has an ATR sticker on top and reads:

HP138_A_
STRIP CHIP
Copywrite 1993

My question is how do I find out what these chips are programmed for?

Thanks,
Taylor
