My used PSG 5 arrived today. I wasted no time opening it up:

Brief description of what's in there, and the project:
Dodge/Cummins ECU

Ya know... probably the quickest way to get all the info on this would be to go to work for Bosch!



Just kidding of course.



We'll be watching your progress with interest.

This will be interesting. I don't expect you'll find much info "stored" in there tho. Keep us posted. Even tho some of us can hardly comprehend what you're sayin at times.

HMMmmmm - not as many devices in there as I would have thought, considering all it does... .



(EDIT)



Interesting, your observation as to all the components being covered with a "gooey substance" - wonder if that is for heat-sinking or similar function, due to solid-state devices dislike for elevated temps - also wonder if the underside most directly in contact with incoming fuel is similarly coated for the cooling conductivity the design supposedly provides?



In view of that heat sensitivity, I've often wondered what prevents far more ECM failures than we see, since it is also operating in a pretty hot environment...
