I just purchased a Proto 2000 UP E8/9 #925 w/Mars Light & #925B; Walthers Part # 920-31739, QSI board, and tried to reprogram the address as 925. It wouldn’t accept the change ( Digitrax Super Chief), and then I reset manually as instructed.
Now it starts on address #3, but runs and stops, runs and stops, basiclly does this constantly. Any help would be appreciated.
Bad decoder? Or is the engine drawing too much current causing the decoder to get hot and shut down, and as decoder cools, starts back running again? The address problem would lead me to think possible bad decoder. Am I correct in thinking you have 2 units, with 2 decoders, to be run on the same address? I don’t think this would be a problem, but may need to program each unit separately. Programming both at the same time could have weird effects.

Some DCC systems require a booster to program QSI sound decoders. The need for a power booster has been discussed in detail on Tony’s Train Exchange’s web site, as well as other DCC system dealers.
For more information about the need for a power booster with QSI decoders, see the following web sites:

The Digitrax web site probably also has information about this problem.
Sounds like a problem to take up with the Union Pacific, since they are the recipient of a premium for the sale of this locomotive, which among other things implys that they have “approved” of this product, and looked into its serviceability.
Just a thought on “licensing”, and its concequences.
The above suggestions above are probably more practical, however.

I bought a Proto 2000 B&O E8/9 with QSI from Tony’s Train Exchange a few weeks ago and had a similar problem when I tried to give it the long address.
I have an NCE Power Pro DCC system. I put the loco on the programing track to set the new address and it couldn’t read the CV. In my NCE instructions it says to continue the process, so I did. The E8 accepted the new address but when I set it in motion it went in reverse instead of forward. Also the momentum that was factory set was no longer working. I changed the direction so it would go forward but still have to fix the momemtum. It will start off slow but when I brake it stops immediately. I know there is a CV that controls the deceleration that I need to change for it to work right again.
