Setting dwell on ego9

[sharpshooter]

I tried tuning the dwell on my ego9 tonight.I have the LPR screw adjusted to be flush with the tip of the lpr cap,and chronoed the gun to 295-305.I started lowering the dwell and found that the velocity started going up to 345+ with the average shots at 264-291-281,with the dwell down to 8ms...from the stock 10.5ms.Now i read that you tune the dwell by chronoing the gun with the stock dwell setting and you keep lowering it until you notice the velocity drop?? once i got the dwell down to 8ms i found that the numbers did drop for the most part with the normal velocity being 265-281...but still had some hot shots in the 291-345 range.Once i brought the dwell up to 9ms i found that the gun returned to its 296-305 range with better consistency....but the velocity really jumped up once i got the dwell down to 8ms with highs of 345fps...so should i leave it at 9ms? or bring it down to 8ms?

My dwell is set at 8.5ms and is shooting at a constant 275-280. That's my Ego09's sweet spot.

So did you chrono the gun first at the stock dwell,and then lower your dwell until the velocity dropped?

And any idea as to why my velocity shot up to a max of 345-365...as i lowerd the dwell? when before with the stock dwell setting of 10.5ms and a chrono of 305

I had chronod it when I first got it. After running around 5 cases through it before plank kit, then another 30 cases before ajusting the dwell from factory setting. Basicly I borrowed the field chrono for a few days. Let the lpr all the way out to the point that it was flush. Screwed it in 1 turn. Then rechrono. Then started adjusting the dwell untill it got down to 275-280. At that point it read 8.5ms.

Ok so after you adjusted the lpr screw till it was flush....and then you re chronoed...what did you chrono too?? did you chrono to 275-280 and just turned the dwell down till the velocity went down below 275-280?? or after you adjusted the lpr flush....you chronoed to around 300fps and then turned down the dwell till the velocity actually dropped?


Because i read that to adjust the dwell that you set the velocity and the lpr first then you keep turning the dwell down until the velocity drops and once the velocity drops...you raise the dwell back up till you get the velocity back up where it originally was...and your good to go with the dwell properly set.

I adjusted the lpr to flush then screwed it in 1 turn. At that point I was shooting 345-362. I started to adjust the dwell down untill it hit the 275-280 mark and left it there. And its also shooting 1500 balls on a 68/4500 tank before I need to refill my air.

Ok so you set a higher HPR pressure....i did not know the dwell was set that way.I thought i read that you chrono the gun to the correct velocity witch we know id 300fps with the norm being 285...and just lower the dwell until that velocity drops...in witch we bring the dwell back up until the velocity goes back up to 300fps.

Not to say you're doing it wrong, but you're doing it wrong. You're not sweetspotting your dwell, you're setting the velocity with the dwell, wardawg.

Sharpshooter, the method you are talking about is how you find your marker's sweetspot. You set your dwell to factory, then adjust the lpr if you wish. I have mine set to 2 turns in. After that chrono your marker to 280 or whatever arbitrary number you wish to use as your benchmark. Take an average reading of 10-20 shots. Now adjust down 1ms on the dwell. Take another average reading. If the average is still close, go down another notch. If it drops down significantly, go back up to the last reading and come down .5ms. Check it there. If it's still consistently in the desired velocity range, leave it alone.

Before you do all this though, I would do an o-ring rebuild on your rammer if you are having consistency issues. You shouldn't be having velocity spikes like you are. Start with putting it back to factory dwell and chrono it to make sure your consistency has come back to normal. If it hasn't after doing new orings on the rammer, then do new orings on the HPR and LPR. But I bet it's your rammer. I was having consistency issues and I needed new rammer orings. (*hint* You did take out your planks, so I wouldn't be surprised if your orings have already worn enough to cause an issue :D.... just sayin)

Ok so then it is ok to have the original velocity that was set with the dwell on the stock numbers drop a little bit?? but just not alot? if thats the case then i was able to get my dwell down to 7.5ms and instead of the normal 295-305....i was getting 271-281....so i raised the dwell back up.What i did first was set the lpr to flush with the body...then turned it in 1 1/2 turns in,and then chronoed to 305 with the dwell set to the stock 10.5.

Then i just kept dropping the dwell and found that as i dropped the dwell the velocity actually shot up at a max of 345-365 instead of 305....i am actually getting pretty good consistency as i got a few readings of 291fps in a row.

The velocity should not jump up as the dwell goes down. When the dwell goes past it's sweet spot, you are at the point where the marker cannot propel the paintball at the desired fps anymore. That is why you raise it back up a notch. By sweetspotting the dwell, you are making your marker the most efficient you can. The dwell controls the amount of time the solenoid remains open. The longer it is open, the more air it uses. The lower the dwell, the less air it uses.

Ok then so as i said i originally set my lpr and hpr with the stock dwell of 10.5 with a velocity of 294-305fps.

So then when i brought the dwell down into 7.5ms and my velocity dropped to 271-281fps....i could have kept the dwell there and maby raised the hpr a bit?? or should i have just raised the dwell to 8ms...and been done with it?


PS.i just put the planks back in....no more 42bps:ak47::ak47::ak47::ak47::ak47::hot temper::hot temper::hot temper::uzi::uzi::uzi::uzi::uzi::uzi::2wield::2wie ld::2wield::2wield::2wield::D:D:D:D:D:D:hot temper::hot temper::hot temper::hot temper::hot temper::hot temper::hot temper:

LOL. Sir, if you can't hit someone with anything over 10bps you have no one to blame but yourself.

But to answer your question, leave the HPR where it is and bump the dwell up to 8.

Its not about hitting anyone...i dont use this ego9 in games...i am a big gun collector and i use this gun in the backyard only and shoot it at targets.:wink2:

The insane rates of fire of the ego always interested me and astonished me and i wanted to see it.But if its going to hurt my gun then i would rather slow it down then have the ram slam the inside of my gun to heck.

I gotcha. I thought this was a marker you used in games. Well then by all means light those targets up! I'm considering taking out my planks and seeing what the speed goes to as well. If I have to replace a few orings so be it.

lol..yeah man i just wanted to see what this could do.I listend to Jack sawhen he was giving a press release that basically he wanted to maintain the speed of the previous ego's but with no qev's...and what he got was something even faster than any previous ego.

Then after reading through forums...i was hearing that the ego9 is not the fastest...and that the ego7 and ego8 were.And i found videos of the fastest ego7 i ever saw topping out at 34bps or so.The thing i came to relize though is that the reason people were probally not seeing the ego9 as the fastest is probally because once they released the ego9.For the most part they incuded the turretts at the beginning...and then the plank kit.


The turretts and the plank kit slowed my ego9 down to the same speed....28bps topps.....and most videos i see with the ego9 maxing out uncapped is about there 28bps.

Well after taking out the planks and the turetts....my ego9 maxed out at 42bps....now i dont know if it was a true 42bps...but i did it a few times while timing my loader emptying.......and going by that and how fast the gun sounded...i can easily say that the speed was doubled....just by the time the hopper was empty with the planks or turretts...and then without the planks and turretts gave me a very accurate measurement that my speed had doubled so i am going to say it topped out easily in the 40bps range...and the ego9 is the fastest ever.


I even took on my friend with a ego7...that was capping at 29bps and my ego9 was emptying way way faster than his.

If Jack Wood said that this ego9 surpassed his wishes for speed than its true...even my father came down stairs after i did a rate of fire test after pulling the planks out and the turretts beore them...and he was not short of words.


Also another thing...im sure everyone has seen the youtube video of Jack wood and Nicky T i belive with a custom modded SL74 ego and firing it and getting 40bps?? and then prazing the gun after for shooting 40bps.....and they were reading this speed measurement using the guns rate of fire indicator.So i think its safe to say i had somewhat of an accurate measurement since i was using my ego9 rate of fire meter.

And to top it all off...i had the gun set to measure average rate of fire...not even max rate of fire!!! so thats something to be said there.If i was using the max rate of fire setting,then it is less accurate since the board records the fastest rate of fire that the gun might have hit during its cycling.Instead i was using the average rate of fire reader so???? i was amazed myself when i scrolled through the menue and saw that the gun was set to read average rate of fire.

After putting the planks back in the gun.I found that anything less than 10.0ms for the dwell is too low,while reading the velocity i keep getting 285-292...and 292 shows up alot......if i put the dwell in the 9ms range the velocity is more in the 285 range.....after installing the planks i returned the dwell to stock and was getting 292-305fps.Once i lowerd the dwell the 292 stayed as long as i kept the dwell at no less than 10.0ms but the 305 disappeared.

Consistency is what you want. Good work.
