Question on speed matching

[Roget]

I have an FT A/B set. I just installed digitrax decoders in both. The B unit runs much faster than the A.
(much more so in reverse) What effect,harm, will this have on the two when coupled together?
Does anyone know how to speed match them so they will run at the same approximate speed. I fear damaging my A unit by having the B unit "pull" it.

Thanks for any help.

If applicable change the speed tables, I am not sure what CVs it would be though. In order to change CV values you need something like a Dynamis, an E-Z Command cannot change CVs (except basic ones like lights, direction, and address).

If Your A-B set was working well before installing the decoders, this will not cause problems. At least You should be able to spot a problem before blowing up decoder.
Avoid using different manufacturers of A and  B units! I would use at least new revised SPectrum diesels!
