EP801 cuts out at high cadence when really going for it

[JuiceStainV&RStick]

Hey all, I'm on a Transition Repeater with EP801. I've got an issue where the motor will cut out when I'm at a high cadence in boost really grunting to get up a tecnical, rooty pitch. It's like I hit the max power output and the motor cuts out suddendly. Doesn't do this at a lower cadence, but there's not enough power to clean these climbs unless giving it my all and spinning.

My riding buddies on Levos don't have this problem, but I'm also a fair bit heavier than them.

The place I ride a lot is steep, rooty lava rocks that are often slick. Cleaning the 8 or so crux moves even in boost is HARD (both technically and physically) and pegs your heartrate. It's a great VO2 max workout! I'm 200 lbs and can put out decent power.

Is this a known thing? Any tuning solutions? The new race mode? I don't need more power, I just need it not to suddenly cut out when I'm really smashing up a section.

Does the screen dropout when it happens, or just the assist? Any idea what your rpm is when this happens? I regularly hit above 125rpm when climbing and never have an issue.

I assume the screen stays on, but there’s no way I could look at the screen in these situations. It’s only a momentary cut out but results in a hike-a-bike.

It only happens pedaling fast, in boost, when trying to clean a slower speed, ledgy tech section and I’m grunting as hard as I can. I assume I’m hitting a power limiter of some sort.

The only times my motor stops is if I hit the speed limiter, or stop pedaling with carryover turned off. Have you tried setting the carryover to max and see how it goes?
