I've yet to see a ecu placed in the engine bay of a car, which would seem 
to me the last place to put one, due to the temperature, and the noise 
and whatever physical phenomena i might have missed. The need to open the 
case, remove the potting, desolder the chip, put in a new one, put new 
potting in seems a major flaw in the computer's design. What happened to 
waterproof boxes? Longer wire? with the effort required to do this to an 
ecu, you could construct a new one, maybe two.

Personally speaking, water and electronics don't mix, even though it 
might be potted. I don't want to have a dig at you about your car 
cleaning habits. If *you* can, that's great, but i'd rather not.
