Which esc do you have?? The LCD program box works with the Xerun pro , Plus and the high grade esc. The other program card works with the quicrun line esc. Maybe that’s it.
@@jstump1972 ok. Well all I can say is make sure the wire from esc to LCD is plugged in correctly and the vehicle turned on. If you haven’t had it more than 30 days try returning it for a new one to see if the issue arises again
