After having my tsunami equipped current release big boy short out, the decoder was replaced by athearn. Since I got it back I have been having an intermitent throttle issue. If you set the throttle on the dcc and dont move it, the engine eventually quits, with proper sound for the slow down and idol. Any movement of the throttle returns to normal/set speed. A factory reset did not fix the problem. Is it possible as a replacement chip this may be some kind of a setting in the cvs that it requires constant attention? My layout has a 3 loop main and an extensive yard so i normally have 3 consists running on the mains and one shunt engine in the yard.
