The Nissan 300zx G4X Plug-In ECU is NOT designed to be used directly with low impedance injectors.
All models this ECU is designed for are fitted with low impedance injectors from factory. Current through low impedance injectors is reduced by the use of factory fitted injector ballast resisters. This means that the ECU is plug-in compatible with factory fitted injector combinations on all models. DO NOT remove the factory fitted ballast resisters.
