CV 2 (Start voltage) works on Lenz and Atlas/Lenz decoders used in their N scale engines. However if you want to set up a speed table you will need to use the 28 step speed table with these decoders. They do not use CV5 (top speed0 and CV6 (mid speed). You will also need to activate the speed table in CV29.

Appreciate the info.
Atlas N scale locos have used a few different DCC decoders over the years, so it all depends on when they were made. There were some with Digitrax decoders, NCE, and Lenz. Some CVs, like 1, 2, 3, 4, 5, and 29 are common to all decoders - part of the NMRA standards. Others like the 116 and 117 used for motor adjustments on NCE are specific to the manufacturer.
If the loco was a DC loco and the decoder installed after the fact - it can be anything. Many manufacturers make N scale decoders that fit Atlas locos.

Gotcha,Happy memorial day.
the old train man Yikes I just found out it was a lenz decoder,I guess my bad. I think nce makes lenz decoders?

No problem I just appreciate your help & input.
the old train man Rich,I bought the engines new but this one is one of the first with dcc.

Rich,I bought the engines new but this one is one of the first with dcc. I just went up to the train room and did 8 to 8 & fine tuned some cvs. It runs fine now. About 6 months ago I decided to get rid of my n scale because I was having trouble seeing fine details etc,well I figured out the lighting in my layout room needed to be upgraded. I bought led lights and installed them,wow what a difference,I thought my eyes were giving out.Well to make a long story short I contacted the guy that I sold my n scale to & he said he was switching scales so he would be glad to sell me my engines back [25 of them].All had dcc & I traded some of my extra ho engines with dcc & sound & got my engines back,all had been run only an hour or so each,now I have enlarged the layout to allow for longer trains & the new lighting solved my problem. By the way I still have all of my ho engines with dcc&sound & that layout takes up the other half of the train room. The reason im telling you this is the guy that had my n gauge engines reprogramed some of them so this could have been part of the problem.Thanks
Peter,I mean when you turn the throttle up,your first speed step starts at 8 scale miles per hour,
What does the OP actually means by jack rabbit starting? Could just need some momentum added CVs 3and 4.

rrinker However - if CV2 is already 0, that's as slow as it's going to go. To fine tune it further, you will need to look at CV116 and CV117 for the motor 'kick'. All the NCE decoders support CV6 for mid speed, as well as CV2 for start and CV5 for top speed. Maybe some of the oldest ones didn't, but all the ones made in the past 12-14 years do. --Randy

Thanks a lot.this helps.
CV 2 (VStart) allows you to adjust starting speed and CV5 (VMax) the top speed. Some decoders (can't remember if NCE is one of them) also allow you to adjust CV6 (VMid).

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
I do not use NCE decoders but below is a link to the NCE site which should show you the manuals.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I have several atlas n sacale engines that came with nce decoders and a few of them have jack rabbit starting.What cv do I use to correct this and what value do I put into the cv? I cant seem to find the answer online.
