Subaru ECU ENGINE Control Unit 22611AJ031 1122005693 7E 

Up for sale is a Working, in excellent condition Subaru WRX ECU.  Fits some 03-04 model year cars. Part numbers listed at top, you must compare this with your original to ensure proper fit and function.  This unity was removed from a crash-damaged car that still ran, so it is a good used unit.

This unit offers a 30 day functionality warranty. This may work with others too but this is the buyers responsibility to figure this out - as always with this type of component your best bet is to match the part number to the one on your original ECU.  

A faulty ECU is one of the most common no start or random stalling problems with these cars. These can also cause issues with erroneous check engine lights as well as emission control & cold or hot start problems. An erroneous check engine light is especially problematic, as the car will not pass the emissions portion of the test at the annual state inspection.If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older. Most Subaru ECU's are located under the carpet just beneath the passengers feet under the stamped steel plate. They are easy to access, all you need is a 10MM wrench.
