I just got a quick question, I drove into a lake and the front of my car was submerged with water. I cleaned out everything and finally replaced the ECU Comp. With one i bought from the factory. However now my mechanic said i need the ECU Comp. Code for it to works .. I don't understand why i would need to code nor never heard of such thing since i bought it from the factory. Anyways i need a little help and i'm pressed for time .. Its a 2005 Honda Accord LX 4 Cylinder engine .. Thanks
