The G4X VLLink Plug-In ECU has been designed to run directly with factory fitted 3Ω low impedance injectors. This means that ballast resistors are not required when installing this G4X Plug-In ECU.
Peak and Hold injection is used to control the factory injectors. When upgrading injectors, it is important to select injectors of correct impedance (2Ω to 3Ω). Please contact your nearest Link dealer directly for more information.
