WRXLink V11 - WRX11X USDM

WRXLink V11 (WRX11X USDM) Plug-In Standalone ECU

Unlock the full potential of your EJ-powered Subaru without touching the factory wiring loom. The Link WRX11X is a true plug-in standalone ECU that drops straight into your factory OEM enclosure, providing Link G4X engine management with an installation as easy as swapping a part—not rewiring a car.

Built for Your USDM WRX & STI

• 2011–2014 WRX STI (GR/GV chassis, hatch or sedan) — manual transmission only
• 2015–2021 WRX STI (VA chassis, EJ series engine) — manual transmission only
• Not compatible with 2010-and-earlier models, which use a different pinout—see the WRX11 ECU—or FA20-equipped WRX models.
• Always confirm your connector matches the header shown in the product photo, and review the Configuration Memo Text in PCLink before setup.

Plug-In Simplicity, Factory Feature Retention

No cut wires, no re-pinning, no guesswork. The WRX11X is designed to sit inside the OEM ECU housing on supported models, keeping your car's factory systems intact.

• Factory DCCD system
• SI-Drive, fully configurable in-ECU
• MFD, trip computer and gear display
• ABS, stability control and all factory safety functionality
• Hill start assist
• Brake pressure, all four wheel speeds, handbrake, Trac mode, diff mode, steering angle and other CAN data available for logging
• All dash gauges and warning lamps work as they should; the CEL can be repurposed as a shift light or knock warning.

G4X Performance Under the Hood

Once installed, the WRX11X provides serious tuning depth.

• Up to 6D fuel and ignition mapping
• Precision closed-loop cam control for four cams, independently
• Sequential and staged fuel delivery
• 5D boost control with three switchable tables, referenced to gear, speed or throttle
• Motorsport features including anti-lag, launch control and flat shift
• Individual cylinder correction and knock control with windowing
• Continuous on-board barometric correction
• Real-time selectable dual fuel, ignition and boost maps
• QuickTune automated fuel tuning
• Gear compensation for spark, boost and fuel
• 512 MB on-board data logging and stats recording
• USB tuning cable included

Connectivity & Expansion

The WRX11X uses a new 4-pin powered CAN connector. Pair it with the CANJST4 cable (Link PN 101-0198) to supply both CAN data and a protected 12V power source, with a self-resetting 3A fuse, to your CAN devices. The legacy CANPCB cable is not compatible with this connector.

Two expansion connectors are also on board, providing extra analogue temperature and voltage inputs, additional injector outputs, a knock input and a digital input—room to grow as your build does.

Before You Order

• Manual transmission only
• An air temperature sensor is highly recommended.
• Double-check your connector against the listing photo before purchasing.
• Review the Configuration Memo Text in PCLink for model-specific setup notes.
• For help confirming fitment, contact your Link ECU reseller or the tech support team.

The WRXLink V11 gives EJ-powered WRX and STI owners across Canada and the US a straightforward path from factory wiring to full G4X standalone control: plug it in, and go tune.
