1.2.2.1 WRXLink (11)
The WRX11 ECU has 4 jumpers on the circuit board, these jumpers are used to redirect analog inputs from
certain pins on the main header that aren’t commonly used in performance applications to the expansion
connector so they can be repurposed for other uses such as extra sensors. For example the MAF sensor is
not commonly used in a performance application, so if an extra analog input is required the MAF input pin
(AN Volt 8) can be redirected to the expansion connector by moving the jumper to the right position.
1.2.3
Injector Impedance
Injector impedance is important and needs consideration before installing the ECU.
1.2.3.1 Subaru Impreza WRX V1-11 ECU
The G4X Subaru V1-11 Plug-In ECUs are NOT designed to be used directly with low impedance injectors.
All models this ECU is designed for are fitted with high impedance injectors from factory. This ECU has been
designed to be used with HIGH impedance (greater than 6 Ohms) injectors. Ballast resistors must be wired if
low impedance injectors are to be used. This means that the ECU is plug-in compatible with factory fitted
injector combinations on all models, however if fitting low impedance injectors then ballast resistors must be
wired. Contact your nearest Link dealer to purchase a ballast resistor pack if required.
1.3 Installation
This guide provides information on correctly and safely installing your new Link Plug-In ECU.
1.3.1
ECU Handling Procedures
The following installation process will require handling of both the Link ECU and
factory ECU. Both of these are highly sensitive to electrostatic discharge and are
easily damaged. Follow the anti-static precautions given in this manual carefully
to avoid damaging electronic components. Warranty claims for ECUs damaged by
electrostatic discharge will NOT be accepted.
