Lionmaster Challenger jerking

When I see the term big jerk, this come to mind.

Back to the subject, I don't have an answer but mine does the same thing. I kinda figured it was a result of the older TMCC cruise lurch issue but would like to know myself if someone has some insight.

This is likely the Odyssey Lurch, it's a problem that some, but not all Odyssey I stuff had.  It also seems to be less pronounced with the Legacy system running in TMCC mode, the old CAB1 only ran in relative mode and apparently exacerbated the lurch.

Anyone remedied this by replacing with a Cruise Commander?

My Atlas (TMCC) locomotives with EOB will not run in TMCC mode with the LEGACY CAB2. I run them in CAB1 mode. I think it has something to do with the fact that I have the EOB programmed to run in 128-speed step mode and TMCC only supports 32 (Odyssey I).

Yep, the Cruise Commander M is a perfect upgrade if you're having Odyssey issues.

catnap, TAS EOB runs best in REL100 mode for the CAB2, that's how I run mine.  You are correct, TMCC only has 32 steps.  The reason it does Odyssey I better is the old CAB1 (or REL100) sends out controls in relative mode, not specific commanded speed steps like TMCC or Legacy control.

I tried R100 mode on my CAB2 and the only differences I could see with my EOB engines was that BOOST increased the loco's speed until it was released and BRAKE brought it to a stop. Also, if I remember correctly, the current speed step was displayed in the lower right corner of the screen along with a speed graph, kind of similar to LEGACY mode.

Up until last week when I got my 990 Command Set I was running my trains with the LEGACY CAB1-L. My Atlas engines ran fine so I run them in the same mode with my CAB2. The BOOST/BRAKE thumbwheel increases and decreases the loco's speed by 1 speed step and that wasn't a feature I noticed running in R100 with the CAB2.

I like that option in addition to the Velocity Throttle for controlling my EOB-equipped engines. Plus, my locomotives don't inadvertently give a blast of the horn like they did with my CAB1-L if I pressed either the BOOST/BRAKE button without the 1 second delay between button taps. The CAB2 BOOST/BRAKE thumbwheel allows me to increase/decrease speed as quickly as I can roll it up or down.

That's an option, I just run them in R100 mode and I'm happy with their performance that way.  I use R100 for the ERR stuff, TAS EOB, as well as the K-Line Cruise equipped engines.  The straight TMCC stuff I use TMCC, and of course Legacy for the Legacy engines.
