We can't give you a number, as each gun is different.

- Lower the dwell setting to the minimum (or an extremely low setting, such as 5 blinks with the stock board, or 8 milliseconds with an aftermarket board).
- Gradually increase dwell until the marker begins to fully cycle. When the marker has trouble cycling, the sound of the bolt firing will be muffled and sound erratic, denoting inconsistencies. When you reach the point where it fully cycles, the marker will make a loud POP for each shot you take, with minimal sound difference between the shots.
- Once the Ion is fully cycling, increase the dwell another 4-6 blinks (2-3 milliseconds with aftermarket board), and that will be your dwell setting.
