Either 1 of 2 ways. You can probably buy a programmer which sets a new map on the ecu. Or you can take the car to a tuner to either open source tune or tune your car and save a map on a programmer. Hope that helps. :)

No. ECU generally stands for Engine Control Unit, i.e. the brain or nerve centre for engine. Without it - no go. With that said, not all cars have an ECU. An older car with a carburetor, old-fashioned distributor and all that will run quite happily entirely without anything even remotely similar to an ECU. A Diesel car may not have an ECU etc etc.
