I am not sure what the settings in a T-board are called but it sounds more like a timing issue. SON (sear on) 3-4ms with 4 being safe, this is how long the pancake noid is energized to release the hammer. CDELAY (cocking delay to allow enough time for gun to fire and paintball leave the barrel) 4-8ms with 6ms is pretty safe. CON (cocking on) the time the bolt will move back to cock the gun and allow a paintball to drop into the breech 30-50ms with safe being about 45ms. Ctime out(time it waits for the eye to see a paintball) 1-2ms. COFF (cocking off) the time it takes to move the bolt back to the closed position 25-35ms with safe being 35ms. These are examples and every gun is different mostly due to the ram being used with or without QEV's, the weight and drag of the bolt, the LPR pressure and the valve and mainspring tension. Most likely the gun is cocking too soon with blowback on the stack and not staying open long enough or trying to close too fast and or the eye not working. With the T-board you need to know the code for the flashing led's to be able to time it. That is the best place to start to figure out what the timing is.
