That is a very interesting article. I had no idea how these things worked. I wish it went a bit more into the tuning procedure. My Kato KIHA 110, which runs awesome on DC, is a very cranky starter with the a Digitrax decoder installed, and activating BEMF only seems to make the problem worse, not better...
