andyb1962 Posted October 25, 2013 Share Posted October 25, 2013 Hi All Does any one have any experience of fitting a DCC chip to a VEP unit DC My NSE VEP on DC analogue control was very good with non of the poor running experienced by others I am using a NCE Powercab controller, Hornby NSE VEP and Bachmann 36-553 DCC decoder (with back emf) I have fitted the chip - all ok, but the powercar will not run properly on DCC. Do I need to connect all 4 cars together again? At the moment on speed setting 1 it shoots off in an extremely jerky manner, and not calming down until speed setting 3 - it is then controllable. Does any one have any ideas please? Cheers Andy Link to comment Share on other sites More sharing options...
Bexhill Donkey Posted January 23, 2023 Share Posted January 23, 2023 I have a NSE 4-VEP. It has a standard Hornby R8249 DCC chip, and that's fine. I would swap the chips and put the Bachmann chip in the other loco. Link to comment Share on other sites More sharing options...
ColinB Posted January 23, 2023 Share Posted January 23, 2023 There is a batch of Bachmann decoders that exhibit this type of behavior. The easy solution as someone said, is replace it with a Hornby or Zimo decoder. They behave a lot better. I think someone said you can play about with CV values, but a better solution is to save the Bachmann decoder for running the lights in dummy unit.
