I have been a little busy lately with chores and house things. I am in contact with a member about finally getting a unit to play with. Hopefully I will have some updates soon. Anyone else that has a known bad module. I really would like to have at least 2 of them in case I make a mistake.

My boss has a C5 and challenged me with reverse engineering and repairing his EBCM. I would like to compare his broken one to some others and see what I can find. I have searched Craigslist and eBay but I cannot find any broken ones at a reasonable price to play around with. I do like to tinker and learn but not when it is prohibitively expensive. If anyone knows of a source for broken modules or wishes to donate theirs to my cause, please let me know. I would rather practice on a separate unit before I permanently ruin my bosses even more than it is.

What are your qualifications to take on such a task? I have one, maybe two, but want to know chances of success and how I might benefit and a way to monitor your progress or lack thereof. As you must know it's the potted component that is now considered unrepairable and which most often fails (TCS NO COMM).The ones I have are 2001 -2004. The failed ones I have are both result of high power battery charger connected. As you can tell I am interested in this project.
That being said I have a strong background in reverse engineering and Circuit/PCB design. I also have access to a network of very expensive tools and other engineers to assist if needed.
Chances of success are ZERO. The units will be destroyed to try and reverse engineer them. The chances of success will increase as the process continues.
Everyone will benefit from the information gathered and hopefully it will lead to a prototype of some sort.
There will be no monitoring of my progress unless someone decides to contract me and put a deadline on the project. All updates will be posted here on the forum with pictures and details of my findings.
If you wish to donate a unit so I have something to get started on that would be great. I have been waiting for a while now and I cant seem to find anyone that wants to let one of these go. I refuse to pay hundreds for a broken one on eBay that I am going to further destroy. Plus hobby funds are a little tight on my end for the time being.

I would like to know if previous attempts to remove the potting were successful. If someone were able to remove it completely without damage to the board or components, I would love to poke around in there with a meter and at least verify basic component function and values...If the board gets destroyed in the process, then reverse engineering will be the only (and very time consuming) option.
The schematic would be worth a king's ransom.

Here some FACTS that I have personally experienced. Not on this Module Microprocessor but OTHER same type of assemblies:
1, The substance is very thick clear, gooey and very sticky. It can be easily dug out. It surrounds the TINY ALUMINUM interconnecting wires that connect the microprocessor board to the output pins. They are VERY delicate and are SPOT WELDED to the contact point.
2. Just messing with the GOOP will most likely break the tiny connecting wires.
3. You are NOT going to solder them in place.

On paper I have zero qualifications. I'm a Mechanical Engineer with a minor in math and kinematics.
That being said I have a strong background in reverse engineering and Circuit/PCB design. I also have access to a network of very expensive tools and other engineers to assist if needed.
Chances of success are ZERO. The units will be destroyed to try and reverse engineer them. The chances of success will increase as the process continues.

If we can send men to the moon and then figure out how to make stuff to get them back when the return trip exploded (Apollo 13), then I think there is hope someone can figure this puzzle out on the EBCM. I say go for it and do not let other failures by others deter you. After all, Apple said no to the Government on the telephone lock but someone (probably to the dismay of Apple), figured it out.

It's been almost 9 months since Wayne Wonders last post on this EBCM Reverse Engineering Idea.
What ever happened to this project ?

That would be the logical way of creating a "fix" wayne. Back in the day, I worked on MILSPEC equipment that was epoxied for weather protection on the Pershing missile. The Epoxy was virtually impossible to remove without damaging the circuit board, thus a broken component was considered trash.
This will probably be the most difficult hurdle to clear in terms of finding a way to repair these things...
