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 tried the Graupner 17.5 and was the most powerful of all those I tried, but it is a motor with considerable mechanic timing, which if combined with plenty of electronic timing can create reading problems of data sensor and switch in sensorless mode(fash green led), I managed to get it working properly having the lowest electronic advances.
I do not know that wrapping uses, but with 17.5 advances should be around (9) and 30 ° (12) 10 ° at most.
