In the flags section of winaldl there is a DRP occured. I assume this stands for 'Distributer Reference Pulse' Whats the significance of this being flagged in winALDL. The computer is receving a pulse signal from the esc in the dist.? Reference pulse is low or high? I see the box constantly being checked and unchecked when the engine is running but dont know what it means when this state is true or false in the program.
