QUOTE (Richard Johnson @ 22 Nov 2007, 09:11) <{POST_SNAPBACK}>***Edwins information is correct however a bit of "how to" advice.
Adjust the Vmax and check - then if needed to fine tune relative acceleration fine tune the Vmid - don't worry about the minimum voltage. 66% of the time Vmax adjustment only will do it, and 90% of the time a Vmax +Vmid adjustment will be enough...s
However DO be aware that it will be very much harder for you to do it with the twin centre as speed tables are really designed for 128 step settings (or at a minumum practical level 28) and AFAIK your Twin Centre only has a 14 speed step setting. This is very coarse and really doesn't give good speed control or ideal slow runnignpotential either.
In fact I hate to tell you but some brands of decoders are progressively dropping 14 speed steps totally as time goes on so there WILL come a time very soon when your Fleischmann system will be less and less usable with new decoders.
The FL is now of course also limited in function control vs most true DCC brands.
Sorry to say it but if speed stepping and fine adjustment is important to you I'd strongly suggest its time to think about Ebaying the Fleischmann and looking closely at a new system.
NCE and Digitrax if a full feature entry level is wanted, NCE & Digitrax are still my favourites at mid price and at the top of the cost tree the all singing all dancing ESU is well worth a look.
All are so much more advanced than the FL system that I think you will be VERY happy no matter what brand you shift to! Both ZTC and Lenz are competent but software-wise they are actually quite tired systems now and far from state of the art - and I'm still not totally convinced about the Hornby Elite hence I did not recommend them, but by all means include them in an "Audition" if U like the look of them.

Thank you both for your advice. Will give the cv values a try and report back.
Although correct about the limited functions of the twin controller I am going to try
and stick with it. I am only just getting to grips with it and dread the thought of
starting again so will probably be asking further advice soon.
