M3 tuning is a little over whelming

[whitetail17]

With so many ways to achieve the desired pellet speed, seems impossible to get the most accurate tune.

I can change my pellet speeds by 60 fps with one full turn of valve. Or turn my adjuster from 16 to 5 and get the same result.

Then you can change 2 reg pressure and change fps as well.

The system is complicated , from what I understand you have to determine a desired speed first get close to that velocity with the valve and then start fine tuning with the quick tune system.

i think its very easy just takes time and really not a bunch of adjustments really needed unless your power house slug shooting

 

[whitetail17]

yes it is easy to obtain speeds and adjustments, but take this for example

.30 cal 44 grain 700mm barrel, pellets..Goat speed 890 fps



reg one 170

reg two 154

power wheel 4

valve line 3

speed 891







reg one 170

reg two 120

power wheel 8

valve out past line 4

speed 891





what is a better tune?

That is an interesting question, of the tunes listed which one is more accurate?. Which one is more efficient with respect to air consumption

I get your frustration. What appears to be logical and very adjustable in the M3 with a few twists of this knob and that dial, along with a reg or two adjustment here and there, can end up being a tuning nightmare if not executed in the right sequence and PSI combinations.

Rule #1

• Document where you are starting from and every change you make from there on.

Rule#2

• NEVER change more than one variable at a time.

RULE #3

• Same as rule #1

Rule #4

• Enjoy your M3

White -

DON'T make gross changes at each adjustment point..! Make small changes.

And learn "exactly"...what each adjustment does, and HOW it does it. Adjusting blind...WILL get you in trouble, sorta like...now !?

Start with adjustment values as what the gun was originally adjusted to. Or go to the FX guys and ask them for a "starting" adjustment for XXX (your main weight) pellet weight..! Write down what they tell you, as you WILL NOT remember it.

THEN...if you really feel the need to try to upstage their tune, again, make...small changes. Start with the thumb wheel (left side). "Small" changes. Then the rotory wheel..."small" changes.

I want the Impact M3 but this is what I am worried about. Lol.

Me too, I like tinkering on stuff but also the old k.i.s.s. principle is hard to beat. I'm thinking one ragged hole, or minute of blackbird is good enough for me
