View Full Version : How-To: "Sweet Spot" your dwell

The dwell setting on each Ego needs to be set up individually by sweet-spotting the dwell to the marker in question. It is not a case of a dwell setting of 8, 10 or 12ms will work perfectly on every marker as tolerances and performance of components within the marker are different. These settings are based off an Ego9.


1. Chrono the marker as it is until you reach the desired velocity; let’s assume you want to shoot at approximately 290fps.

2. Remove the rubber grip screws on the right hand side of the Ego and push the set-up pushbutton on your circuit board to enter the set-up menu.

3. Scroll through the menu and "Unlock" the circuit board.

4. Close up the grips again so that you don't lose the three screws that you're about to drop!

5. As the marker is now unlocked go into the DWELL parameter and lower the dwell by 1.0ms from 10.5ms (the factory setting) to 9.5ms.

6. Chronograph the marker and check that the velocity has remained approximately the same.

7. Again go into the DWELL parameter and lower the dwell by 1.0ms.

8. Chronograph the marker again to check that the velocity has remained approximately the same.

9. Repeat steps 7 and 8 until the velocity starts to drop.

10. When you reach this stage your DWELL is set too low to achieve the velocity you require. You must now raise your DWELL by 0.5ms from its current setting.

11. Chronograph the marker again to check that the velocity has returned to the desired value. If it has not then increase your DWELL again in 0.5ms increments until it does.

12. When you are content with the velocity readings, exit the DWELL parameter and "lock" the marker so that you are tournament legal.

13. You have now sweet-spotted your Ego's DWELL to maximize its efficiency at that particular Inline Reg setting.


Again, these settings are based on an Ego9. The process is the same however for all Ego's.

Very nice write up!

Maybe toss in there what marker you are basing your stock settings on...Someone may read that and get confused because their stock settings arnt that.

But awsome job!

Fixed. :thumbs up:

Though it should be noted that Planet Eclipse recommends you break in your Ego before you mess with dwell settings. Some people say 3 cases, some say 10.

13. You have now sweet-spotted your Ego's DWELL to maximize its efficiency at that particular Inline Reg setting.


Which means that if you adjust your velocity, your dwell is no longer sweet-spotted. So unless you shoot the same paint, at the same temperature from the same batch... You're going to have to adjust your velocity (aka inline reg pressure) which kind of (IMHO) defeats the point of it. Can anyone prove otherwise that keeping a standard dwell setting would be bad?

I think that adjusting the dwell down from stock for efficiency purposes on an average box of paint, with a stock barrel (no paint to bore matching with a kit) would still be beneficial.

I almost always adjust my output through my inline each time I play anyway.

Keeping your dwell at the factory settings ( 12.5 or 10.5 depending on the marker ) will not affect performance either way, so those who don't like to tinker...don't think that you have too.

I set the dwell in 4 diff egos ( 2x 08's an 06 and an 09 ) based on 285fps to 10.5ms and have no issues.

The proper break in should be 10 cases recommended. Then a simple breakdown and wiping, then start toying with board settings.

Not to sound like too big of a newb...but what exactly does the dwell setting do? Why would you want to change it? What does changing it do for you?

I'm still a bit of a newb when it comes to these things too. From what I can gather, lowering the dwell decreases the amount of time the solenoid is open per cycle. Lowering it from stock should (correct me if i'm wrong) theoretically lower battery drain, and increase air efficiency when properly tuned.

Oh, OK...that sounds like it would be very beneficial then!

Man...the learning curve from the A5 is quite big...hahaha

That is 100% correct.

Bear in mind, that a setting too low, and it will not be open long enough to function.

But when you lower your dwell, you must increase pressure to compensate for the lowered dwell. So how does this help increase efficiency?

no you dont need to increase pressure, when you lower it that far that you have to increase pressure, then you lowered it too far.... lowering dwell decreases the amount of EXTRA air that is wasted when you fire a shot. only XYZ amount of air is needed to project the round at a certain fps. so you tune it so that only the exact amount is needed is released. too low then it doesnt fire for crap, too high and you waste shots, and your bps is affected.
