ECM part #s
I pulled down my ECM and noticed that the part number on the outside of case is 16198262. This is a 91 trans am 305 automatic car. This part number does not seem to match up to any on the FAQ sheet on this website. Is this the correct stock ECM? Also how do you determine the part number of the PROM? I pulled the cover off and the only thing that I could see was AXXB3063 and 1P1168. It has delco written on it so it is not an aftermarket chip.

The 16198262 is a replacement ECM for the 1227730 (aka 730). Same thing, different part no.
The AXXB BIN is not available on DIY-EFI.ORG but there are similar there. But you can work with any automatic BIN for the SD system, though a 305 is still best. It's nice to see what's on the AUJP (L98 SD BIN) as a guide.
