Why I nosedived?

Hallo experts,

XRV/Hypercore, CBXR Batt, VESC FW 6.02, Float pack here.

Configured like this: loaded FW 6.02 and Motor.xml + App.xml + Float.xml received from Tony @ Floatwheel and strictly followed the GTV / XRV / PintV Power Kit Start Guide.

Did hundreds of miles without any issues. Just one strange thing: sessions from Floaty app detect Max controller speed more than doubled the Max GPS speed.

So, today, I decided to check the Wheel Diameter in motor setup.

To do this I’ve followed the VESC Tool helper here https://supzero.ch/vesc_config/ so I backup the config and Changed all the suggested Motor setup parameters of the tool:

Wizards/Setup Motors Load Default Parameters NO
Setup Motor/Usage Usage EUC or Balance
Override (Advanced) YES
Setup Motor/Motor Motor Large Outrunner
Override (Advanced) YES
Max Power Loss 400
Open Loop ERPM 700
Sensorless ERPM 2000
Motor Poles 30
Motor Selection yes
Setup Motor/Battery Battery Type BATTERY_TYPE_LIION_3_0__4_2
Battery Cells Series 15
Battery Capacity 6.7
Advanced YES
Battery Current Max 20
Battery Current Max regen -16
Setup Motor/Setup Direct Drive
Gear Ratio 1
Wheel Diameter 279
Motor Poles 30
Detect all motors over CAN Bus NO

and run motor detection.

Went out for a test ride and after Few miles… BANG… WASTED at around 17 Mph. Fortunately I was fully protected so no boken bones… I restored the backup with the VESC app and went back home veeeery slowly…

What was wrong?

I attach everything from the recorded Floaty session; just change the extension from xml gpx json and csv.
