1227302/1228092 swap with 1227727

[7399MGM]

Newbie--- I am restoring a '73 MGB swaping out the old 4 banger with a 2.8 V6 out of a Chevy S10. It had TBI injection which I want to change to MPFI from a Pontiac Firebird. I have all three ECM's and the wiring harness from the S10 and Firebird. I never did eprom programming and need help. I know I need to purchase a reader and or burner/reader. I also need to use some software. But most of all I need the ECM diagrams for both cars to be able to identify where the 1227727 came from. The label on the chip are DELCO 9733 2346 the label on the blue cover are DELCO AUBS 2672. Can anyone help me with this? Are there any Youtube videos showing how to accomplish the chip reading and programming? I know its a lot to ask, and I have been souring the net but did not find anything. BTW the labels on the 1227302 DELCO HNR 5639 and on the 1228092 AZNU 0435. I believe those label numbers denote which car there from, right?

Thanks

If no one posts anything about the programming aspects, I'll try to get back to this tomorrow.

For the quick answers, the three or four letter codes identify the calibration and can be used to look up some vehicle information. It is possible for the code on the computer to be different from the code on the chip inside, so if there any doubts it's best to check for a code on the chip. Here are the results for the codes you posted:
