I read somewhere, possibly one of the gearhead-efi threads, that the $0D vs $0E had to do with the trans 60e vs 80e. Never saw anything I took as concrete.They're somewhat interchangeable (I looked at the $OD too), like I said the $OE I have is a newer version but, it shouldn't make a difference. Here's the link to everything 7427. @EagleMark, RIP, has the $OD in this. He also has a bunch of .bins, Dave w built a spreadsheet for tuning too.
