This value controls the amount of time (in milliseconds) the solenoid is
energized. If too low, the marker will not cycle. If the value is too high,
the solenoid remains on too long, wasting battery power and air.
In brief, dwell is the name for the amount of time the marker will open the
valve to release pressure to fire the ball. Because of this, increases in
dwell generally cause increases in velocity, and decreases generally cause
lower velocity (however there are working limits to this). Dwell can affect
a number of other things, including but not limited to velocity,
consistency, efficiency, and maximum rate of fire.
The dwell setting on your marker is what allows the bolt to fully cycle
from shot to shot. If dwell is set too low, the bolt will half-stroke and
the gun won't fire properly. If set too high, the valve will be open for
too long and air will be wasted, decreasing efficiency. Because of this,
it's generally best to use the lowest dwell setting possible, while still
keeping it above the point where the marker has trouble firing.
Dwell is a trade off between "too high" and "too low". Accordingly, there
is no such thing as a "perfect" dwell setting. Some guns will require a
higher setting than others, depending on the parts, manufacturing
characteristics, weather conditions, etc etc. Each gun requires a bit of
experimentation to find the optimal setting that should be used.
Default - 15
Min Value - 5
Max Value - 25
Now that the background info on dwell has been covered, here is one
possible method for finding an optimal dwell for your G3. These
instructions are based on the fact that the G3 does not currently come with
a gauge. In other guns using the pressure as a starting point to work off
of is sometimes the easiest option. Without that on the G3 it would be too
easy for someone to over pressurize (and possibly damage the solenoid) or
under pressurize (and cause firing inconsistencies) if given that extra
variable to play with.
1. Set the dwell to the 15ms setting. This is the stock setting on the G3
and should provide a good (conservative) starting point.
2. Using good paint and a chrono, adjust the velocity to your normal
operating range (under 300fps). In effect, this will set your pressure to a
good starting point and address the issue described above. By using the
15ms setting you should have good consistency and be well within the safe
operating limits for pressure.
3. Remove all paintballs from the gun and turn the eyes off. The next few
steps involve dry firing only.
4. Adjust the dwell to the lowest setting.
5. Increase the dwell 1ms at a time and dry fire at each setting. Stop when
the gun begins to fully cycle. At the low settings the gun will sound
erratic and muffled. When the gun begins to fully cycle each should will be
loud and sound very similar.
6. After the G3 is fully cycling, add another 2ms to the dwell time and
that is your new dwell setting.
7. Add paint, turn eyes back on, and adjust velocity to the correct range
using a chronograph.
This dwell setting should provide very good shot to shot consistency, while
still allowing optimum efficiency. The dwell is just high enough to fully
cycle the bolt for each shot but not too high that it wastes extra air by
holding the bolt forward too long.
How to Adjust Dwell:
1. Pull and hold trigger while turning on gun (tap power button).
2. Pull trigger to cycle through LED colors until Green Flash is displayed.
3. Tap power button. LED will blink current setting.
4. Tap power button again. LED will quickly cycle through all colors.
5. Pull trigger the desired number of times.
6. Tap power button. LED will quickly cycles through all colors. Setting
7. Hold power button to turn off gun.
8. Tap power button to turn gun back on with new setting.

The first case is different from some other boards I've used, in which the
number of "clicks" it takes to set the setting starts at the min valu.
The second case is true for all modes.
