The WRXLink V11 (WRX11X) is Link Engine Management’s G4X plug-in ECU for the Subaru WRX and WRX STI V11 (GR/GV/GH/GE hatchback/sedan, MY2007–2011) with EJ20 or EJ25 turbo engine. It is the most fully-featured Subaru plug-in in the G4X range — all factory systems are supported including DCCD (Driver Controlled Centre Differential), SI-Drive, hill start assist, cruise control, dual AVCS cam control, and ABS integration. An onboard 4-bar MAP sensor is fitted.
Denso ECU only: The WRX11X requires the factory Denso ECU. Some North American models (late 2007–2010) were fitted with a Hitachi ECU instead — the WRX11X is not compatible with the Hitachi unit. Verify your ECU manufacturer before ordering.
CAN note: Uses 4-pin powered CAN connector. Use CANJST4 cable (101-0198) for CAN devices — the older CANPCB cable is not compatible.

Frequently Asked Questions
Does the WRXLink V11 support DCCD?
Yes. DCCD (Driver Controlled Centre Differential) is fully supported — the factory DCCD dial and modes operate normally.
How do I know if my WRX has a Denso or Hitachi ECU?
Check the ECU label. Some North American WRX models from late 2007–2010 were fitted with a Hitachi ECU — the WRX11X is not compatible with those units. If uncertain, contact us before ordering.
Is a base map included?
Yes. A startup base map for the EJ20/EJ25 V11 is pre-loaded. Professional dyno tuning is required before use.

Note: This Plug-in features a new 4 pin powered CAN connector and cannot use the old CANPCB cable for CAN connection. Use the CANJST4 (Link PN 101-0198) cable for connecting CAN devices. This new 4 pin port and cable provide not only the CAN connection, but also a protected 12V power supply and ground for powering the CAN devices. The power supply is protected by a self-resetting fuse rated at 3A continuous.
