Well, aside from that critical event, there was also record of RPM's, and a full variety of other engine operational data and measurements on that record. They always provided a copy of it for me and it was a couple to three pages long
So, I'd surmise that PSI pressures (over pressures) and the like would be recorded also (if BMW/Mini does data log) even though they are not critical (but abnormal).
I don't have a dog in this hunt and cannot say whether Merc Marine data logging is different to other motor manufacturers. Only relaying what I know from personal experience with that particular piece of equipment.
