decoder speed setting

It's probably impossible but is there anyway to get two different loco's with
different decoders to run at exactly the same speed.
My fleischmann twin centre dial goes from 1 to 14 and whichever speed
setting you try there is always a slight difference.
One loco set at 4 the other at 5 and it pulls away, both at 4 and it falls behind.
I sort of need a inbetween setting. Any ideas please.

Are you sure about that? 14 step is the *only* mode that is part of the DCC standard (S-9.2). If it is not implemented then these decoders will never gain a conformance warrant.

S9.2 specifies the baseline packets (14 speed step only) and, as the standard, is what all comliant decoders must implement in full.
QUOTE Personally I think its no loss....
Oh, I agree, I just think it will cause even more compatibility pain in the short term if, say, the standard were revised to include what is now in the RP. There's very little to be gained in a decoder by dropping support for 14 speed step packets.
