What is Roller Bench Mode for?

What is this feature for, dyno? Also, what should the engagement point say, learned or no state?

...Not sure, but if I had to guess it would be dyno or road test. I would recommend that you check with your BUDS software team and let them explain it to you.

Good Luck with Your Mission. ....

Yes, on supported machines, it allows you to dyno it without causing a limp mode....the one you get when the rear wheel is turning but the front wheels are not. It was discussed briefly in this video. If you don't want to watch the whole thing, start at the 11:00 minute mark.

When you plug into a supported machine, I suspect that the No State will change and tell you the state, ie Enabled / Disabled. When you're in the Settings Menu for the correct module, I would think that item would be in the Options tab, and you can toggle it there, but I’ve never personally used it.

Someone at Pit Bull or Lamonster Garage would probably be happy to discuss it with you. They made the video.

It can be a little confusing, but you're screen shot shows the Settings tab. No state means that you haven't selected the current BUDS2 session to do anything with that particular setting. If you select Engagement Point, you can then enter into the testing and learning function for that. If you run the test of Engagement Point for example, then it will show Learned. No State does not mean the the TCM never learned the engagement point. Roller Bench mode is for any activity that involves letting the rear wheel turn without the front wheels turning to prevent faults such as ABS. Most people think of a dyno test as running at full power. A roller bench can be used to set belt tracking for example.
