Can someone shed light on why my esc is cutting out at WOT. Running a 4.5 turn with 10-15 degrees timing in a touring car with 8.1 fdr and a 8000 mah battery.

2-3 minutes into a heat I lose all throttle and brake primarily when the esc is is at wide open throttle. I’ll lose all braking power as well and the esc resets it self( does the start up sounds) until it’s under high load again.

everytime this happened the esc and motor were between 120-135 degrees. The low voltage cut off is off, temp cutoff is off , throttle limiter is at level 5

i can’t see the 4.5 being to much considering tekin sells a 4.5 as a combo…
