Internal combustion engine (ICE)
...gas, diesel, steam engine = engine

Electric motors = motor
...NO combustion goin' on

ECU (Electronic Control Unit?)
I think your referring to a speed controller
...look up/do some research on speed controllers
...like, maybe Paul & Sabrina's DIY speed controller (lots of "great info")

It certainly would help to provide a more clear description of what you want. You have a vehicle which is driven by a DC electric motor; are you now
  1. looking for a different motor speed controller?
  2. wanting to replace the electric motor with an engine?
  3. wanting to add an engine to make the vehicle a hybrid?

Is it one of these, or something else that you are trying to do?

What type of motor is that? It's not clear from your question if you're asking about getting an off-the-shelf motor driver (controller) or building you own.
If later, you need a micro-controller, preferably automotive qualified. Then you need to design a schematic/PCB with high-power FETs/IGBTs and write a firmware for everything.

Thanks - now we know what you are actually asking about.

Since this is a forum for do-it-yourself conversions of vehicle to electric power, and you want to convert from electric power, this seems like the wrong place to ask for help with this.
please explain this
i have seen this

You want an engine control unit; this is a forum about electric motor controls... and everything else about electric cars, but not cars with engines.

i have seen this...
Yes, every modern vehicle has an electronic engine control unit, similar to what you see in that image. I think that you should buy one, not try to build one, but it isn't the subject of this forum either way.
