The bin file on my car now is #16243643. Which is a 97 L67 bin that is one of the listed ones that are compatible. I also think we were having trouble with any of the other 97 files wanting to write to the pcm. If it's a 97 file and my OSID is 16252965 should it matter? Did you happen to look at the scans?

MAF is brand new AC Delco as well.
