The symptoms of ECU failure are likely simmilar to any Bosch computer (Unless you have one of those Fenix boxes... but hopefully you all know better) -- With ABS, you get fantom sensor failures. You might get a toasted Turbo RPM sensor on a non-turbo engine. As for the transmission computer, don't worry about it. Odds are the magic weld inside the transimission will pop long before the computer is supported by Linux.
As for the rule that heat and vibration shorten the life of electronics, this is true. However, it *is* the job of the electrical engineer to not only consider the voltage in the wire, but the heat in the box as well. This is not the 3GHz P4 sitting in your bedroom... Or the 233MHz MMX that would be sitting in your PC in 1995.. This is likely a 25MHz Motorolla *designed* for use in embedded systems without any kind of cooling. It may even be a more rudimentary and cool running machine like a Motorolla 6800/MOS6502 or Intel 8253--the kind of processor used in AT and PS/2 keyboards... Bet you didn't know your keyboard had it's own processor...
If you grab your National Semicondcutor ALS/AS Logic Databook (I know you all have one), you'll notice that the most complicated chip in this book, the 74ALS876A comes in a publically available military spec version known as the 54ALS786A. The 54xx version reacts a little slower, but is easily comparible. And the major differance is that while the 74xx will operate between 0°C and 70°C... The 54xx will operate between -55°C and 125°C. Not all chips are built the same.
Either way, point made, it's not a blazing computer in there... How much horsepower DOES it take to divide by 14?
Wow... I need to update my tagline. I've put 8 thousand more miles on my 850.
