A Legacy engine control computer reads sensor input and calibrates the fuel and ignition systems. If it isn't reading and calibrating, either of those systems is in danger. The transmission is also affected by the ECC. Before you get stranded, replace your faulty ECM for Subaru Legacy with a new one from AutoZone. Enjoy the convenience of online ordering and savings on delivery with Free Shipping on $75 or more. When you need it today, choose Same Day Store Pickup (in most cases) at the location nearest you.
