16052541 hlk ecm, what is this ecm from?

I have an 85 iroc-z tpi 305 lb9. It had this ecu in it, I recently swappes to a 87 165 ecu. My question is about the original computer. I looked for information on it but cannot find any. Does anyone know if the original computer is from the 85 iroc 305 lb9 or was it swapped in? Thanks for any information.

The hlk bcc was from a 85 tpi 305 automatic used in the 1226870 ecm. The 870 ecm was used in tpi 85 y and f-body and the 2.8l

Thanks. The other thing I was wondering, is the 16052541 ecu different from the 870? If so any idea of what is different.

Ah well that makes more sense. I was confused but now I understand. For some reason I thought it would have 870 on it. Thanks for all the info.
