This product supports the following North American (USDM) models:
- 2011-2014 WRX STI hatch or sedan, GR/GV chassis code, manual transmission only. (note 2010 and earlier models used a different pinout which is supported by our WRX11 ecu Part # 238-4000).
- 2015-2021 WRX STI VA chassis code, must have EJ257 series engine, manual transmission only. (FA20 engine not supported).

Unsupported Models:
- 2008-2010 USDM models which have the international Denso ECU pinout. For compatible ECU, please see WRX11X Part # 238-4000
- 2015 onwards WRX VAG models which have the FA direct injection engine

Important Notes
- Please check your connector matches the header in the listed photo before purchasing.
- This ECU works for manual transmissions only.
- Air temp sensor highly recommended.
- Most factory features are supported including DCCD, hill start assist, SI drive, cruise control, cam control & ABS supported.

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.

Supported Features:
- Driver's Control Centre Differential (DCCD)
- SI-DRIVE (can be setup to adjust anything you like in ecu)
- MFD display, trip computer and gear display
- ABS, stability control and all factory safety functionality
- Hill Start Assist
- Brake pressure, all 4 wheel speeds, handbrake, Trac mode, diff mode, steering wheel position and other CAN data able to be used for logging or other strategies
- 8 Injector drives available to allow sequential staged injection for big power engines
- All other dash gauges and warning lamps working per factory. Check Engine Light can be used for other functions such as shift light or knock warning

Unsupported Features:
- The Security/Key lamp will remain illuminated in some models
- Secondary Air pump (emissions)
- AC Request and CEL (CAN bus controlled) have been reported as not working on some 2013-2014 models. This should be a simple firmware update to fix but we haven't yet been able to find a car with this specific problem to test. Please contact tech support if you suffer this problem and are technically capable of helping investigate
