How can i use four coil on plug (CDI) with eune ?

Cdi= capacative discharge ignition cop= coil over plug this being cleared up: you need to make a logic board with microcontroller to read the distributor along with the ecu, and control which coil to send the ignition pulse to. If you had an obd2 oil pump, you could accomplish this with the ckp and crank sensors wired to your control box, and have the microcontroller feed the ecu all of it's 'distributor' signals, while still having the microcontroller route the ignition pulse to the correct coil. Not an easy task for the laymen.
