FX Impact m3 .22 compact settings

Fantastic! and no, you need to decrease the pressure from reg 1 not 2. You should be getting nearly 170 shots with your gun shooting those number if you fill to 300b. The difference between both regs is too high, bring the first reg to around 120b and you should be good, emphasis on should. But it'll be around that +-10bar
Oh really? I was taking @Trucker3573 advice on that one as he told me to set reg one to 150 and leave it there.

Would lowering the first regulator to 120 cause the refresh rate to be lower? I thought having a higher first regulator pressure would help keep pressure against the second regulator and help it open and close more efficiently, but I am willing to try dropping it down to 120.

I never take my gun up to 300 bar. I usually fill it to the 230 to 240 range just to keep the stress down on the entire system. I definitely don’t need more than 100 shots in a tank but if I can get there on a 250 bar fill, that would be great.

I will try lowering the first regulator down to 120 and checking the consistency again.

The range is supposed to be 30-40 difference. If you make the range too small or too wide, you nullify the effects back of having to regs. You can try raising it 5b more and leave the 1st reg 150b and see what that does for ya. And then if it does nothing, then try what I mentioned.

I’m just curious why you think I should change anything When the results were so good. What is the benefit of changing anything if it’s extremely accurate and consistent?

For a better efficiency, a well tuned and efficient gun will result in great accuracy at both short and long distance without any surprises. Idk how far you plan to shoot, but an inefficient means yours wasting air, so at short distance you're doing great, but in the long run it could destabilize. Also, the compact is supposed to give you about 115 shots shooting 18.13gr pellets going between 880 and 900fps so, something is off.

If you're happy with it, I would say leave it. But knowing from experience, I personally wouldn't be able to leave it alone after a while lol.

Yeah it sounds like I’ve got wasted air for sure but the system seems so stable. I guess I don’t have much to compare it to since this is my only PCP besides a Notos.

I will try adjusting the regs to 120/80 and give that a shot and see if that brings the efficiency back. I may be over-hammering also because I think I’m at nearly the peak speed for the tune and should probably be closer to that 95% speed area and not be hitting it as fast as it can go. I may need to raise to 85-90 bar to get it up into the 900s and hammer down a little to bring it back to 890s.

I will give this a shot tonight or tomorrow and get back to you. Thanks for continuing this journey with me 😂 I appreciate it.

I get it, sometimes it doesn't make sense. But just because your tune looks good and your shots are good doesn't mean that the whole system is happy. You can certainly make it work, within certain means. Just make sure to make changes one step at a time.

Are you near the peal or at the knee? Peak would be 100 and knee would be 95-97

On that tune I was definitely near the peak. I dialed the hammer back a little and didn’t drop velocity so I’m pretty sure I was a little over the peak. I didn’t spend too much time dialing it in, just played with the hammer a bit and shot.

I just changed the regs and got them at exactly 125/85 but will have to dial it in tomorrow. A few extra bar on reg 2 and brought reg 1 down to 125 for a 40 bar difference. I’ll dial in the hammer tomorrow and do a “true” 95% tune to be sure I’m at max efficiency and let you know what I come up with. Hoping to be in the low 900s and dial the hammer down to 900 and maybe get the valve adjuster involved to bring me back down to 890 where I was today. Should be MUCH more efficient and right at the knee 👍

Awesome! Hopefully you won't have to do too much tuning lol.
Well…definitely worse after this new tune. Worse on air, worse ES and SD, and worse accuracy. Tuned exactly the way you suggested and it got worse in every way. What do you suggest? Tuned at 85/125 on regs at about 96% of peak power. Not consistent at all.

I take it you also tried adjusting the valve lower?
 
Yes I did. As soon as I got the valve to cut down on fps it got much worse as far as consistency goes.
Try try what you were initially going to test out which is bumping the 2nd regulator from 80b to 85-90b with the power wheel at 16, valve at 4, and micro hammer adjustment at 2.5, and work your way up on the hammer and see what results you get, if this doesn't work then set it back to where you were yesterday. I'm sorry your gun is out of tune again.

I'm sorry your gun is out of tune again. I’m dropping like 2 bar per shot and I don’t get why. I don’t hear wasted air and the settings all seem so mild.
This is essentially what I did today. Gun is currently at 130/90 on regulators. Started with valve at full open and hammer around 2.5. Found max velocity and started coming down from it. I’m getting so frustrated with this entire situation. I don’t understand what I’m doing wrong. I don’t know where to go from here.

Thanks

Sorry I meant to state to put the 1st reg back to 150b
 
Just brainstorming here, but do you think the gun should be on the pellet port or the slug port? The gun is currently on the pellet port but now I’m wondering if I swapped it over to the slug port what kind of difference that could make.
For what you want, keep it on pellet port.

I’m going g to keep at it and see if I can figure it out. I don’t know what I could be doing wrong. I’m doing the exact same thing I see in most of the videos and tutorials that I’ve seen. I feel like I am getting some weird consistencies when dialing up or down the hammer, like a sudden drop or sudden spike in speed. I think I’m just going to go with a very low reg pressure and bring it up very slowly until I get to my target speed and fiddle around from there. I still don’t understand why I’m getting half of the amount of shots that FX states that the gun should be getting With the hammer at 2.25 or so and the gun shooting under 900 ft.pers I don’t know why I’m only getting 60 or so. Shots from 250 bar down to 120 Ish.

The ONLY thing I can imagine is for some reason I’m over-hammering and causing air loss. But at only 2.25 or so on the micro, I can’t imagine that being the case.

If your reg is set to eighty bar, you can shoot your gun down to ninety bar no problem. Oh, those sixty shots in a hundred and thirty bar is a lot of air to go through for a low velocity. Where in florida are you?
 
I’m wondering if my expectations are too high or if I just can’t find a tune that works properly…I keep finding my spreads opening up to 15-20 fps no matter what I do with regulator/valve/hammer combinations. And at 25 yards I’m expecting my shots to be hole in hole but they are not. I was measuring some of my groups from today and the better ones were about 1/4 inch at 25 yards which I guess is acceptable. I just find the gun being finicky and not as consistent as I had hoped for. I’ve tried a bunch of combinations but just can’t seem to get it fully dialed in. I suspect part of it is my abilities shooting from a bipod and supporting the gun with my rear hand, but it just seems like one will hit EXACTLY where I’m aiming and the next will be 1/4 inch off. Maybe that’s normal and I’m crazy. I want my spreads to be under 10 and SD under 2 but can’t seem to find it. I’m shooting at 910 currently but maybe I need to try slowing them down.
being a new member here but a member turbocoupe 88 who is NM-FXM4 has a couple videos on you tube
he has these fx impacts m3-m4s figured out, he tuned my gun today after his mods its crazy accurate and in a 15 20 shot string.
no more that 3-4 fps spread don't care if the gun sits a week 1st shot to last. I've heard all the negative there is no fix blah blah blah.
take a look at the video i posted in. what did you do air gun related today.
tell ya what he is like a kid in a candy store waiting for this new leopard.
he said i can't wait to take it apart, he is nuts.

I am in Palm City but work down in Jupiter. I agree it’s a lot of air to lose over the course of 2 magazines. Something just seems off and I know I’ll figure it out. I just feel like I’m playing ping pong with the settings. I’m not giving up 😂
