I need assistance with an OEM ECM, I have a bunch of spares from my collection of LH's and I have one that I may have killed.
I understand the fundamentals of how it works, but my question is...


HOW do I get rid of this hard jelly stuff so I can access the board? I started digging with a knife but I don't want to risk physically damaging the board. These are available as refurbished so there must be a way to get it out of there.
I figured the Hive may be able to direct me to something that will work safe enough.
Thank you in advance.
Glad nothing's wrong with Mojo ;-)
I guess my first question would be, Do you know what this Substance of Doom is and where it came from? If you do, then I think what you want is somebody who understands chemistry to tell you how to dissolve it or liquefy it or attack it with a magic goop that separates it from the board. Or maybe freezing the whole thing would make it more tractable? (I *assume* an ECM is certified to survive down to minus 40 or so....)
In reply to Stealthtercel :
It's likely conformal coating that everyone used to protect boards many years ago. It was put on thick for automotive computers.
On the LH platform this lived behind the drivers side headlight, so its seen cold and wet.
I'll check the article, and hopefully I can figure something out. I have like 5 or six of these things, just the one that's broken and wouldn't mind seeing how hard it would be to fix and 'tweak' if possible.
