I know that some people on here have had trouble with megasquirts - car not starting, intermittent reliability, etc. I am making a post here to illustrate how not to put together a megasquirt. Some common sense and best automotive practices should be used when putting together the ECU. You will see below some big no-nos. These include poor solder joints/cold solder joints, wires that are not tidy and are just left floating in the case, burnt insulation, and extra components that are attached to the case with just silicone (instead of a proper fastener).
I work in the automotive industry, specifically control systems and have had a lot of exposure to failures due to parts not being built to spec. The MS is by no means heavy duty but building one properly will go a long way to a reliable setup.
The ECU below was sent to me to fix, so make sure that when you put an ECU together or have someone put it together for you, they place components properly on the board, solder well, and make sure parts are not just moving around in the case. Vibration is a real problem, and having a tidy design not only avoids problems but really helps with troubleshooting when there is a problem.
