I’ve got dual Torque Board’s 6355’s, Focbox Unity and a 12S4P battery.
I just sensored my 6355’s and I noticed that I have way less power. I use to use 58 amps and it felt plenty fast and now at that it’s just lethargic. What’s going on?
I tried bumping it up to 70 amps and once I get going it’s decent but off the line it’s so slow, it’s ridiculous. Also I’m running 60 battery amps, -10 on regen and -60 for motor amps. Also I’m confused on how to know what the maxes can be for my battery and motors?

To calculate your max battery discharge we need a bit more information.
Correct me if im wrong, but one of the main advantages of sensorsed mode is to provide rpm data allowing the esc to apply power more gently under load.
Sensored mode is most useful for starting from a stop – or starting if you’re rolling backwards. Once the motors are turning, it makes little difference.
Did you noticed a difference in old and new Unity firmware?
Somehow I feel like the latest firmware isn’t as torquey as the old firmware, but haven’t looked into the acceleration curves.
I’ve also noticed this on my new build.
Running Foc sensored with dual 6374 and my previous build was bldc uncensored dual 6355.
The old build felt more like a wild beast compared to the new one.
Try lowering the sensored RPM. The speed estimator on the VESC kinda sucks tbh, sensors are only useful if the motor cannot synchronize to open loop commutation, which normally happens with hill starts and high inertia loads.
That’s not been my experience so far. I had Carl Collins help me with my remote disconnect issues and one of the things we did was the test erpm in the unity app. Maybe that could have done something?
