The G4X MR2Link V2-3 Plug-In ECU is NOT designed to be used directly with low impedance injectors.
All models that this ECU are compatible with were fitted with a low impedance - ballast resistor combination from factory. This means that the ECU is plug-in compatible with factory fitted injector combinations on all models. If high impedance injectors are to be fitted then the ballast resistors will need to be removed. Contact your Link dealer for further information.
