I think I have it working now, it just needs some tweaking to make sure that I got all of the settings optimized and I'm not overheating the motor at the max RPM I set. Make sure and set the battery ratio ($x) to 0 in the firmware since you're presumably not running with balance wire. I'll take some screen grabs of everything I did later this week when I have a chance. I'm still not sure where to set the max RPM, but per Magmotor the maximum amperage for the motor should be around 25 amps, so that's what I'm using on my high speed cutoff.
For others using the VESC tool, if you get faults like this, take your scooter back to the computer, open it up and connect to the computer before you disconnect from the power. You can then use the Terminal Faults tab to see what happened. This was really helpful for me when I somehow set the max battery amperage to 30 and it was cutting out every time the amp spiked a little....
