I am still trying to get temps right running sensored only, need more time. I run offroad 17.5 so not exactly the info you need, but still relavent.

I am still running dual mode, seems to be just as quick, more torque, lower rpm though but the temperature is more stable (does not react as much to FDR changes as the sensored only mode) For 2 wheel I run 20 degrees at the motor with no timing advance in the esc, for 4 wheel I have 10 degrees in the motor and full advance in the esc.

Just got the 194 software so when I get some time will have another go at getting it right.
