The G4X AltezzaLink Plug-In ECU is NOT designed to be used directly with low impedance injectors.
All models that this ECU is designed for are fitted with high impedance injectors from factory. This means that the ECU is plug-in compatible with factory fitted injector combinations on all models. If low impedance injectors are to be fitted then a ballast resistor pack will be required. Contact your Link dealer for further information.
