They always work great until they lose all the advanced timing. The green light on the speedo flashes which indicates the speedo has overheated ? however the speedo / motor are not even hot. I even disabled the overheat function on the speedo but it still had the same symptoms with the green light flashing and loss of advance timing. Admittedly if I tried it an hour later it would be fine again.
Typical settings :-
FDR 5:1
Boost 50
No turbo
DRS 2
RPM /ACC 400
This problem can be after 1 minute or 4 ? I bought a second motor but it still did the same.
I have run with turbo and without. it makes no difference - Has anybody had this problem / know a solution ?
Thanks in advance
I've had the same issue with the 930 software on three different motors, its as if the car goes in to sensorless mode for no apparent reason.
I solved it by turning off the low voltage protection. I think what may be happening (especially with the corally) is that the power used on the motor under sever load suddenly drops your battery voltage below the 6v, once it does, the esc switches into safety mode.
Since i've changed the cut off, I've had no issues - try it and let us know!
Your settings seem fine - although I would give it slighlty less boost with a little bit of turbo - then watch it go!!
