Yes I'm also considering sending the Porter back. Unfortunately it's connected whith high shipping costs and a lot of paperwork.

Thank you Ton

I've already guessed that I have to do that.

Thank you for your answers. I´ve already tried CV 8 to 8. The problem isn´t solved. I took a short video. Probably it will help to understand what´s wrong. First the porter runs with sound then I turned it off. Then you can hear a light buzz from the locomotive but it doesn´t move. After some seconds and opening the throttle the porter starts to run.

Thanks for every help.

I´ve just got a new Porter 0-4-2 DCC with Tsunami Sound Decoder. The engine runs smooth. But if I change the direction from forward to backward or the other way the locomotive doesn´t move until the throttle is on 12th speed step. Strangely the exhaust chuff starts at the first speed step. I´ve already "played" with the starting voltage, the accelertion rate, the speed tabel and the forward and backward trims. Any suggestions? Thanks for your help.
