To view the shot counter you simply enter programing mode so that you can see the revision number (e.g. rE1.2) and then hold the joystick in the down direction. It will display a 4 digit alphanumeric number. Type that into an online hexadecimal converter and it will give you the number of shots that FCU has cycled. If you have a "high mileage" engine and you have reached the maximum number for those 4 segments, the count will continue to another 4 segments which can be viewed by pressing up on the joystick. Those are simply placed in front of those displayed on the "lower" display.For example, the down direction on the joystick displays 3bcE and the up direction displays 0006. You put the 6 in front of the 3bcE so you have 63bcE which equals 408,526.
