I have successfully installed an ERR kit in a Williams ten wheeler (no simple task in a small tender). After programming, it worked just fine. Then I noticed that I had duplicate ID numbers. I attempted to change the ID for the new engine, following the steps in the TMCC/Legacy handbook. I can't seem to make the engine forget the old ID and adopt the new. I think I am following the instructions correctly. They don't seem to be hard to interpret. Now, I think I am at the point where the engine doesn't know what its ID is. Is there a simple procedure to correct this problem?
