I seemed to be able to run my trains on 4.3 once I understood the little quirks and how to get around them until recently. I have 2 engines that I recently bought. They are newly released MTH PS3 diesel engines, one a Premier and another a Rail King. For the Premier, I only get smoke out when I set it to High, nothing on Med or Low. Also when I first start it up, I may to play with the smoke settings until it works on High (Seems like it forgets the settings from last time. I have even made sure to save the settings using the remote key). Other than that, it appears to work fine. As for the Rail King, I have several issues. Once I power the layout, it will come on and billow smoke out. No other engines do this. Once I start it up, I can turn off the smoke and it runs fine. Sometimes I have to reset the engine to get it do what it is supposed to do like it doesn't remember the settings. For this engine, I also have a non-DCS issue. The engine sounds like it is hitting something as it runs on track. It may be the truck hitting the undercarriage of the frame, maybe near the speaker. No other engine does this.
All other engines, PS2 and PS3 works fine. Just my 2 newest ones. Is this a 4.3 quirk and does anyone know how I can correct this?
