I just uploaded 3.29 FW, I'm testing in 30 minutes. I'l report back as soon as I get home.
Here are my new settings:
Motor max: 70A
Motor min: - 60A
Battery max: 40A
Battery min: - 25A
Brakes are much better now, almost as much as the 2.54 FW, but still at high speed if you pull the brakes hard you feel less braking power than the old firmware.
There was a huge difference in power delivery going on motor max from 60A to 70A, the 6374s are shining at its best now.
I still feel uneasy pulling such big amount of current onto the battery, I need to make a log as soon as the Bluetooth app starts working
