If the thing runs backwards there is a CV you can reprogram to change it. Stan- I have the GP 40 and the same set up as you but haven't had much time to tweek it. Which Cv did you change and to what? What is your Speed Table like?

If you change the speed table you can get rid of that pulsing at startup. I tweaked my speed table just a bit and it helped but it needs more tweaking. I'm like you and very new to the DCC thing so I am making adjustments very slowly. I am hoping to get a DCC group in the club and hopefully someone else knows more about it than me. It would be nice if there was more shared info about DCC settings in these forums (more like try setting CVxx to YY). I've got QSI's Quantum programer that works on the computer. The nice thing about it is that you create a computer file for each loco. If you have duplicate locos and want them all set the same you just use the same file. Why did you set CV 29 to 0? I set mine to 12. The info I got on that is to use the table on the bottom of the QWire instruction sheet for a standard speed table OR set CV 29 to 12 or 13 (depending on which direction the loco is set at) for a custom speed table (which is what I am using in the GP 40). I just finished a QSI install on a U25-B last night with the CV 29 set to 2 per the instructions. There is a function, I forget which it is maybe button 11 or 12 that when standing still the decoder will "talk" the decoder address and when moving will "talk' the loco speed. Nice to play with. With it 115 degrees outside right now I can't run much of anything outside.
