The problem with the whole thing is DCS is a 2 way system and that is what is patented. I assume the tach reader figures the rpm of the motor and then computes the speed using the gear ratio of the truck and sends this back to the remote. Lionel cannot do this because the way it is done may be patented (what other way would there be?) AND the most important reason. The engine cannot talk to the remote. So anything displayed in the remote can only be a guess based on the relative speed step/voltage sent out. The ACTUAL speed will vary based on the load and what the cruise control is doing to keep the speed constant. To give you an idea an MTH engine with it's motor turning 1175 RPM with a 3.5 gear ratio in it's truck and 1 1/4 in dia. wheels would be going 60 SMPH. Easy hard coded math and then sent to the remote. Lionel can do all the math in the engine but there is currently no way to get the answer back to the remote.
