Stuart G Posted February 6 Share Posted February 6 I have encountered an odd problem when modifying the configuration C.V.s on LokSound V5 decoders. I change the following C.V.s to these values: CV27 - 000; CV29 - 026; CV47 - 001; CV49 - 017; CV50 - 000; CV124 - 036 The result is that when I start a steam locomotive, the Chuff Rate is absolutely 'mad' and attempting to synchronise the Chuff Rate C.V.s (CV57, CV58 & CV249) has very little effect. Reconfiguring similar C.V.s on Zimo decoders does not cause any such issues. Can anyone offer a reason why this happens? Link to post Share on other sites More sharing options...
Hamburger Posted February 6 Share Posted February 6 Did you also change CV2? This has a big impact on chuff sync. For example, if CV2 = 1, you should start with CV57=200 and CV58 = 50. And before that (but after setting CV2) you need to do the CV54/F1 procedure, see instructions. Link to post Share on other sites More sharing options...
Stuart G Posted February 6 Author Share Posted February 6 I did chnage CV2 to '001', not realising that this would affect the Chuff Rate. One option open is to do a 'factory reset' (CV8 - 008) and re-configure the required C.V.s, leaving CV2 at its original value. Link to post Share on other sites More sharing options...
