This unit offers a 30 day functionality warranty. This MAY fit other year Legacys 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. 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. These are located under the dash, on the driver side of the car. You can view the part number on your original from below without taking too much apart.
