I was there for Gary's flameouts, and for two others I knew about. All were fixed with setting the ECU to 8 cell NiCd.
This may have just been coincidence since according to Mr Matt (JetCat Tubine Clinic), the voltage settings only affect low voltage indications and alarms, not how the ECU mangages the different voltage. (
