This is for a 2004 Subaru WRX STI.. Engine control module. It has the factory mapping on it and is completely unlocked  If your looking to get rid of an immobilizer from 2005-2007 this is the ECU you need.,Or you have a car that is locked to an ECUTek or COBB map and you cant use it. this is what you need,, Also, I can help if you have any questions or needs with doing the ecu swap or basemaps, tuning or just anything related to these ECUs. I have years of experience with this, I can be very accommodating just reach out. I repeat there is no COBB or ECUtek or any other kind of locked/lockable type software on this ecu, its ready to go. Will ship the same or next day of payment with USPS Priority Mail. I work 60 hours a week so If it isnt same day dont hold it against me but I generally have them in the mail by the next day at the latest.  

If you want this for a 04 Forester XT I have exactly what you want and need. Just ask..  AlsO DO YOU NEED EJ20X mapping? Need It? Reach Out... 

If you are doing a harness merge to use this in a GC chassis and need ANYTHING done to this before it goes out let me know. CEL Deletes etc.

 22611AJ241 : 22611AJ240 : 22611AJ242 These are the only legit 04 STI ECUs without immobilizers. If it doesn't have one of these codes on it its not from an STI .

These can be wired to run any 32bit EJ (3 Wire Cam Sensor) Engine fairly easy. Reach out.
