EGO/ETEK tuning

[Slither]

So if you couldn't tell I am having a slow duty day so here is something else ripped from somewhere else for those that want to tinker.


Here is a quick reference guide to set up your Ego Dwell and LPR pressure to ensure that you get the best longevity and performance from your marker (along with a few other helpful hints to ensure that your marker stays in tip-top condition).
For best results we would advise you to set up the LPR first, Inline Regulator second and then dwell third.

- LPR setting. The output pressure of the LPR will directly affect the speed at which the rammer travels. If the output pressure of the LPR is set un-necessarily high then adjusting it lower would reduce wear and tear on the rammer bumper o-ring. Obviously taking it too low could result in other issues such as drop-off or inconsistent velocities so to ensure a sufficient margin for error do not turn the LPR screw in more than 2 ½ turns.

- Inline Regulator (HPR) setting. With the LPR set to your preference (as described above) adjust your Inline Regulator pressure so that your marker chrono graphs at approximately 290 fps. This is so that you get realistic efficiency figures after setting your dwell.

- Dwell setting. 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.
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 push button 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 the factory setting.
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 Egos DWELL to maximize its efficiency at that particular Inline Reg setting.


Note #1
If you start breaking paint after you dwell tune you probably want to up it 1.0 ms or so because the delay is to short.

Note #2
This works for a all years of EGO the principle is the same

Note #3
About the LPR
In = less wear and tear on internals but possibly less consistency
Out = possibly more wear and tear on internals but more consistency.
I keep mine about 1.5 turns in. Stock is two turns in from flush for all years I belive.

I hope this helps some of you and it is by no means necessary to do this as we all know they work just fine out the box.

For those curious about what is "Flush"

[Aardvark]

I didn't have any questions as to what "flush" meant. Just wondering if you were on the same page. Nice read. I'm gonna love sharing what I learned from the LV1 class with you.

[Slither]

I do dig all the techy stuff and really want my LV1 to get here already. I have the feeling I am merely a padawan talking to a master though.

Our earlier back and forth did get me thinking on this though and I figured I would post it up.

The picture was added later on the thread I stole it from because the question " what is this 'flush' you speak of" did come up. I figured it was worth a grab.

Question for you though, I bought an LP valve guide for my 8 on a whim thinking it might quiet it down. I haven't installed it yet but I am wondering if it is even worth it? If I install it should I change anything else parts wise? My searches have been less than informative on the subject.

[Aardvark]

I've got a bunch of LP and HP valve guides for the 08... Nothing else needs to be purchased to run either. But at the same time, nothing really changes. Unless you're putting two Ego8s side by side with the LP guide in one and HP in the other, then run shot tests against each other, you're not gonna notice any difference in your performance when you're actually playing. If Nicky reads this, he might crucify me for saying that, but there are plenty of other people that can confirm this. (Course, there's also a bunch of people on PBN that'll SWEAR it shows improvement in their game... but whatever).

As for quieter... eh, I can't speak on this since I intentionally tune my poppet markers to be as loud as functionally possible. As for what I stated above, I was just covering the presumed conservation of air efficiency improvement.
