VEP and DCC

[andyb1962]

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

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.

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.
