ENTERING PROGRAMMING MODE Enter programming mode by holding the trigger back,and then pressing the power button to turn the marker on. Once in programming mode, pull the trigger to cycle through the available parameters. If the marker will not switch into programming mode, the Blackheart board is locked. The board will need to be unlocked before changes can be made. When the desired parameter is selected, enter its new value by pulling and holding the trigger until the power LED turns off, then pulling the trigger a number of times corresponding to the desired setting. The LED will blink a number of times to confirm the new value that has been set. To exit programming mode, press the power button, turning the marker off.

FSDO (LED: Slow Blinking Red) When a marker rests, its bolt may stick in position, causing a low-velocity shot the next time it is fired as the bolt un-sticks (First Shot Drop-Off.) FSDO compensation increases the dwell time on the first shot in a group in order to compensate for bolt-stick. FSDO may be adjusted from 0 (off) to 15 milliseconds in 1 ms increments. When the marker rests for 20 seconds or more, the next shot fired will have the FSDO value added to its dwell time. The default FSDO setting is 5 ms.

Google, 30 seconds.

Not sure on the inner workings of this gun but make sure there isn't a build-up of lube on the back of the hammer where it meets the hammer assembly.
