break in

[younggunna6898]

so how long is the break in period, and tell me if this is the correct way to tune the lpr and dwell. 1. Raise dwell until the velocity stops raising, and then lower the lpr until it didnt cycle, and the turn it up until it does and i can rip on it. 2. OR, do i lower the lpr to where I like it, and then adjust the dwell until it is the most consitant.

ive been wondering this myself actually(my break-in period will be up soon). with other guns they say to turn up the dwell till the velocity doesnt go up. not sure how or if that applies to the quest as well or not. but with all guns its my understanding that you want the lpr set where the bolt fully cycles and then turn it up 1/4 to 1/2 turn and leave it.
everybody has diff settings on thier guns, and every gun will be a bit different even from ones of the same kind, but there should be some kind of "rule of thumb" for how to set it. there was another post(in a different thread) just recently someone explained a bit of how it works. or is supposed to work. but from what i can tell about some folks here is that they go with the lowest settings they can that are consistant and dont have fsdo.
id like to have some numbers to start with as well to tweak from.

oh......btw......break in is a few (3-5 or so) cases of paint. or equivalent dry shots. id rather run the paint thru cause its quieter, and you get feedback on whats happening with your shots, but ive put alot of dry shots thru it too while terrorizing the neighborhood.

can somebeody post how they tuned there lpr and dwell?

I guess i will call FEP when i get my quest to see how i should go about adjusting the dwell and lpr.

It's taken a while for mine to get broken in, so I've gone through the pains of tuning it.

To adjust your LRP, there are various ways, but this is how I do it for Spool value like markers. It's fast and dirty, but works.

I leave my Dwell set at 8ms, which is stock. I raise my LPR until it cycles with no bolt stick and can rip. I then raise it up just a tad to adjust for the extra pressure it will need to move a ball as well as just the bolt. Maybe an extra 5psi or so.

I then take it to a chrono and put some paint through it. I will raise the Dwell to about 12 and then put paint into it. If it cycles without any FSDO or bolt stick I'll lower it 1ms until I have problems, and then raise it back up 2ms. From there I'll tweak my LPR and see how low I can get it while it still cycles without any problems with paint.

The right way to do it is a bit more time consuming. You go to a chrono with your LPR set to about 90psi (by the book). You put paint in and shoot. You raise the dwell (starting at 8ms) until it is consistant. If you're getting bolt stick, raise the LPR by 5psi and start over until you can get consistant shots over the chrono. If you also can't get it consistant, you then raise the LPR until it is consistant, and start with adjusting the dwell again.

A lower dwell or lower LPR isn't always a good thing. You want to find the sweet spot for your marker where it cycles the fastest for you and is also the most consistant.

Incase anyone doesn't know how the LPR and Dwell work together, the LPR pressure is the pressure of the air that is moving the bolt back and fourth. It needs to exert enough force (pressure) to move the weight of the bolt and a paintball forward. The Dwell is an electronic setting that tells the IC on your board how long (in miliseconds) to keep the air pressure exerted on the bolt (i.e. how long to keep the solenoid open).

So if you're LPR is set to 90psi, you'll have 90 pounds per square inch of force exerted on your bolt. If you're Dwell is set to 10ms, then you'll have that force exerted on the bolt for 10 miliseconds.

If your bolt sticks or your have FSDO, it's sometimes caused by the lube on your bolt causing it to stick or move slowly. To counter this, ABS (anti-bolt stick) settings temporally raise your dwell to keep the pressure on the bolt longer. If this doesn't work, then the pressure (LPR) on the bolt is too low and needs to be raised.

Well I hope that made sense to everyone who didn't know. :tup:

isnt 90 psi a little high? I like your way better lol.

i think i will still call FEP to make sure
