Subaru ECU 

2003 Subaru Legacy Outback ECU ECM engine computer 22611AH05A JA18000D9M

Up for sale is a Working, in excellent condition 03 Subaru Legacy outback Engine Control Unit. 

This was removed from a recent crash damaged but still running, 03 Subaru Legacy Outback Wagon 2.5L w/ an Automatic transmission AWD.  This unit offers a 30 day functionality warranty. This should fit others too, & 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.
