I've recently entered the world of DCC, espically DCC sound chips. Overall, I am pleased with the performance of my factory fitted class 20 sound chip (once I'd adjusted the volume !).

However, I've recently expanded my sound fleet, with the purchase of a class 66 (shanks) and Class 37 (Coal Sector) but have found that both these models do not perform nearly as well as the class 20. With major lags between slowing down and the sound catching up, engine shut down sequnecies not work etc.

I've have been trawling the various forums to look for posts on the CV values that need adjusting to resolve these type of issues, but haven't really found any clear answers, so I was hoping those who may have had DCC sound for sometime, or have already revised the CV values may be able to offer these settings to the forum for any of the factory fitted decoders.

I appreciate that sound is a very subjective topic, but any suggestions would be welcomed.
