Here are some high res unresized pics of the innards of the three modules. I used macro mode with my cheapo compact camera but you can see quite a bit. All about 1mb
The Bcm & Mcm have the same cpu H8/538, the Ecm seems to have a different one.

Talk about complicated!!!! Where do I adjust the points then. LOL
All have a programming 10 pin connector?
Examining the data sheet I see the H8/538 has two seperate serial data channels, that explains the METSCI1 & METSCI2 connectors as well as the BATTSCI1 & BATTSCI2 ones I was looking at.
I might try seeing if the SCI pins on the cpu are connected to the pins on the plug to confirm this in next few days.
