If you change the whole set you can kiss the ECU goodbye. One may not do too much damage. The air-cooled injectors have approximately 4 ohm coils and a resistor is used to reduce the current. The water cooled injectors are ~16 ohm and get the positive voltage directly from the fuel pump circuit. 4- 16 ohm loads in parallel = a 4 ohm load. 4 ohms at 12 volts = 3 amps being switched by the ECU. 4- 4 ohm loads in parallel = a 1 ohm load. 1 ohm at 12 volts = 12 amps. See the problem here? All 4 injectors are wired together in parallel and controlled by only one output device.
