What’s The Best Brand of ECU?

My question is what would be examples of inputs and outputs ?

Inputs are usually sensors: Digital like crank and cam sensors, wheel speeds, and switches; or Analog like Oil/Fuel/Manifold Pressure, or temperatures like Coolant or Intake Air temp, or a driver knob.

Outputs are things controlled by the ECU, like Injectors, Coils, Solenoids, Relays and warning lamps.

There are also input and output communications for communicating with a computer for tuning, or an electronic dash or other device.
