You say the loco you are trying to pair it with has an MFX decoder. Are you using MFX there or DCC address? Is your tender a different address from the loco? You wont be able to use the same address for both if the loco is using MFX and the tender is DCC. You will need to set them up in the CS3 as a consist and then they should run together with separate addresses.
For the tender problem the CS3 DCC programming leaves a little to be desired. Do you have access to another type CS to try programming the emotion M (like a Massoth 1210z?
