I needed a pcm for my truck a while back-For a while I was searching for a truck with the same trim level, but ended up finding one for an XL model, 2wd whereas I have an xlt 4x4 with esof. I was concerned it wouldn't function properly, particularly the esof, but It plugged in and worked without issue.
I can also say that the 6.0 excursion PCM is different as well as the excursion is equipped with PATS, while the superduty is not. As far as them being identical electronically, I don't know. I'm fairly sure you can re-flash the pcm to a different calibration entirely, but I don't believe the SCT does that-I believe it just alters parts of the calibration. ALSO, the 06 pcm uses the information center for all sorts of oddities-even more so than my 05 does. I have no idea what would happen if you installed a 2006 pcm in an older truck without the information center.
If you really care, I have several PCM's (03, 04, 05, and 06) along with all the trucks that they belong to. I could try a chinese firedrill for see what happened while hooked up to my scanner-see what codes were set.
