Title: dynamis

I'm having issues wit my dynamis controller...at random engines will speed up to full throttle and sometimes they will stop in other words the controller is controlling its self.

have you tried disabling the analog feature in those locomotives? this would involve reprogramming cv29.

Check the batteries in the handheld - sounds like a weak signal.

anaolg conversion is a setting in the decoder which allow a dcc locomotive to operate on dc layouts. it's a nice feature, in theory.
in practice, sometimes when a dcc system is first turned on, and the decoders "wake up" they respond to the analog rather than their digital address.      in this case, the decoder is reading the full dcc voltage across the rails as a speed command, and the locomotive takes off at top speed, oblivious to any commands that you may send it. you have to turn off the command station to stop them.     the solution is to disable the analog festure so that the decoder only respnds to commands to its address.   

this is done by reprogramming cv29 in the decoder. if your command station is capable, read back the value of cv29, subtract 8 and reprogram the new calue to cv29.

I have had these problems also when the batteries are low.
