I thought it was likely related to an address pb. It has happened to me several times. When moving to a 4 digit address, using a programming booster and service mode is the best way. Make sure you can check the key CVs after programming.

Whether with Decoder Pro or the Cabs.

I have not run into this problem with a Tsunami.
One thing about doing a reset on the Tsunami's. After you have entered the reset numbers you need to remove the power to the unit or the reset will not be completed.
The decoder in IM Gevo is Soundtraxx Sound decoder. Luckily, we managed to fix the problem. But, it was very strange. I have never seen the decoder which had problems like this. I have programmed many different decoders and I have never had any problems with changing direction in CV29.
The decoder should respond on address 3 after reset. It never happened. We tried both - programming on a program track and a main track (DCC system is Prodigy Advanced). We were able to program decoder (the model was moving a bit after each CV programing). We programmed CV29 back to value 6, CV 1 to value and we still couldn't run the model. It didn't respond on any address.
After this I was trying to find a solution in the internet and my frustrated friend was trying to find the address which loco could respond on. He started from 1 to 200, after it he tried 9999 and..... 0 :) Bingo ! Loco respondedon address 0. Then we programmed CV29 to 6 for address 0 on main track and CV1 to 3. Everything was ok. Finally we changed CV29 for 7. Problem solved ! :) My friend has a model which respond for address 3 and runs in reverse. It should be a simple operation. Insted of fe seconds we we speny a few hour :-)
If anyone will have similiar problem - try address 0 :)

Who makes the decoder? Could it be a Digitrax decoder? What is is the address? 35 in CV29 would require a 4 digit address. Make sure that CV19 is 0. Also hit F6 twice if it is a QSI decoder that is in shut down mode.

I pray every day I break even, Cause I can really use the money!
I started with nothing and still have most of it left!
1. Your CV reset values look good.
2. How does he know the decoder did or did not reset? These decoders require a programming booster(normally) to program in service mode, otherwise it should be done in ops mode.
3. CV29=35 is one of the correct values to run normally in reverse.
4. IMHO, he should check CV29 in service mode to see if the 35 value took. Sometimes the 4 digit addressing can be a problem to get it to take. He can also check the values in CV1,17 and 18. The loco not running could possibly be due to an address problem.
5. I like to program these decoders using Decoder Pro as it is much easier to track what has or has not really changed--and to make sure I didn't make another mistake.
Hi,My friend has a problem with IM ES44DC. He tried to program decoder to have a loco in reverse so he set up CV29=35. Unfortunatelly, the model doesn't run after it. The sound starts but engine doesn't respond to any order. I found a manual for soundtraxx decoders and told him that he should enter CV30=2 or CV8=8 to reset the decoder. He claims that it doesn't help.
Are these values are right for resetting a decoder in IM Gevo? Any other idea? How to set up CV for reversing a direction ?
