Option 1 : All 4 PWM control valves wired together so they activate all together according duty cycle managed by ecu map.
Option 2 : Each PWM control valve connected to primary injectors (example injector 1 with PWM nozzle 1 etc..) Since the injection needs to happen on boost the ecu switches on pumps when the engine is on boost and manage flow according PWM duty cycle managed by ecu map.
What do you think Richard/Rotrex ?
