Hacking/tuning the jeep ecm

[JeepsAndGuns]

I am curious which microprocessor your ECU has. I have been searching around via Google and found that some of the SBECs used the exact same Motorola processor that the DSMs use, for which there is documentation available.

Not sure how I could find out. If your not having any luck finding out, I doubt I would have any luck. Would the numbers off my ecm help? Its the factory original ecm, and its a 93 wrangler 4.0 inline six, and a 5 speed manual trans.
Also, pardon my ignorance, but what is DSM?
