This stuff is pretty exciting. On the one hand, it's basically just TBI reheated and sped up. On the other hand, it offers digital control over things that had always been strictly mechanical. I've done some time with PWM and I can see how this tech could really save some maintenance costs... and wonder if that's in the best interests of corporate minds. Oh, and I am really impressed by the 562. I may just have to get me one a' them.
