Had a GT2.0 Pro fail on me last weekend and had to purchase another speedy to continue the race meeting (state titles), hence buying a brand new Prostock. Ran the same settings as the GT2 using 323 software in 13.5 boosted and experienced this problem. A fellow racer also has the same problem with his, only his feels like it goes into sensorless mode, turn it off then back on and it goes good for a couple of laps again. Mine is not as bad but still concerning.
settings are as follows
SP MMM 13.5 FDR 6.95
DRRS 6
low voltage cutoff 3v
boost 42
turbo slope 18
turbo timing 16
turbo delay 0.1s
start RPM 4000
ACC 500
Lipos are fairly new and it didnt happen with the GT 2.0 Pro
Any Suggestions?
i had this happen in 17.5 boost here in perth. i swapped motors and problem was gone. possibly a sensor cable or plate problem. what is your temp when the problem happens ? if its not hot, then id look at sensor cable or plate, Cheers.
