I got a xtreme stock esc, I accidently crossed the battery wires only for nenosecond. the sensor? board is burned out, but in sensorless mode, it work ok fine, smoothly accerlate. but when i connect sensor cable, it will not move at standstill unless i push the car forward. any idea how i can fix or resolve it? can anyone repair this? i has this esc for 2 years,

I was told, you can run motor down to 5.5T without boost with certain firmware with xtremestock, is that true?
