programming CVs

[Berkshire]

hi everybody
I have recently bought on e-bay a lot of Bachmann locos "DCC on board". The locos are the followings:
n. 2 USRA light 2-10-2
n. 1 4-8-4 Northern Santa Fe
n. 1 SD-45
n. 1 GP-7
n. 1 GP-35
I have a Digitrax Super Empire Builder.
My problem is: what value I must insert on CV2, CV3, CV4, CV5 and CV6 to obtain good results of acceleration, deceleration and starting voltage?
Thanks a lot for your help and sorry for my bad english.....
Greetings from Italy
Paolo
