You only need to power the setup via the 12v in to the speeduino. Some sensor inputs and outputs need the 12v supply to operate correctly.
You should not be using the onboard PSU of the mega especially with 12v .
Whilst programming etc it is perfectly ok to use just usb only, but be aware of the effects some inputs and outputs may show as mention above
Sensors such as coolant are simple two wire types that are connected to ground one side, the speedy on the other.
TPS on the other hand ( three wire) use the gnd and +5v with the output to speedy
