WRXLink V11 G4X PlugIn ECU

The Link WRXLink V11 (MPN 243-4000) is a G4X PlugIn ECU engineered to deliver the latest in engine management technology, maximizing your vehicle's performance potential. This engine control unit supports a wide range of North American (USDM) Subaru WRX STI models. Specifically, it is compatible with the 2011-2014 GR/GV chassis code WRX STI (hatch or sedan) with a manual transmission. For the VA chassis code WRX STI, it fits models from 2015-2021, provided they have an EJ series engine and a manual transmission; the FA20 engine is not supported. It is crucial to verify that your vehicle's connector matches the header shown in product images before purchase, as different model years may have distinct pinouts. The WRXLink V11 retains most factory features, including DCCD, SiDrive, MFD display, trip computer, gear display, ABS, stability control, and hill start assist. It can also utilize CAN data for logging various parameters such as brake pressure, wheel speeds, and steering wheel position. Advanced G4X PlugIn features include up to 6D fuel and ignition mapping, precision closed-loop cam control for four cams, sequential fuel delivery, digital triggering with OEM patterns, and 5D boost control. Motorsport features like anti-lag, launch control, and flat shifting are also included, alongside onboard barometric correction and QuickTune for automated fuel tuning. Expansion options are available via two connectors. Expansion Connector 1 provides inputs for An Temp 4, An Temp 3, An Volt 4, An Volt 5, An Volt 6, and An Volt 7, along with +5v and Ground. Expansion Connector 2 offers Knock 2 input, DI11, and outputs for Injectors 5 through 8, plus +5V and Ground. Note that this Plug-In ECU features a new 4-pin powered CAN connector; it cannot use the older CANPCB cable. A specific CANJST4 (Link PN 101-0198) cable is required for connecting CAN devices, providing a protected 12V power supply and ground for them, protected by a 3A self-resetting fuse. An air temperature sensor is highly recommended for optimal performance.
