Tuning my Alpha Wolf, help please..

[Richieg]

Im trying to tune my Alpha .22 in advanced mode. At the current time it's chrono is not working, so I'm using an external chronograph. So let's say I'm tuning 18.13 to shoot at 880. According to the factory setting, optimal BAR is 99, dwell is 1946 and volts are 68.0.I entered all the info, shot a 10 shot string and the shots were 916-920. NOW...trying to get it to 880? Should I leave the BAR pressure where it is and reduce voltage and or dwell ? If so which one should I turn down, how much, and does it matter which I turn down and or why? Thanks for any schoolage you may have to offer.

It doesn't matter...
I tend to modify the volts... less digits.
If you look at it as percentage, 1 volt change @ 68 V = about 1.5%.
A 1.5% change in 1946 = 27.

So you would modify the volts until you reached the desired 880fps and not change the pulse at all?

Hammer 2200, voltage 62, Bar 80 with sd under 1.5
JSB 18.13 with 880 fps for my .22 Alpha Wolf 23” barrel
It’s a tack driver. Hope this helps.

Thanks, I will try that, but why are those numbers so far below what the factory say in their programming. I thought the numbers in the programing from the factory should be closer to perfect.

I don’t know. But when I used the pre-programmed advanced mode settings for 18.13 JSBs, my fps was in the high 900s when my regulator was 110 bar.

I try not to approach the extremes in the settings, but really, that shouldn't be a problem either... with one exception... we were warned that running the board on max voltage for long could damage it. With anything I've shot in mine, not been close, even the 30 cal @ 100 ft lb still not too close to the max of 88V.
This is likely a confusing thing to a lot of people but it's one of the beauties of the DW/AW... you can get to the same point a lot of different ways and they're all likely to be good.
So yes... I just adjust the Volts for fine tuning unless whenever it's at, the Volts are starting to near the extreme.
Take notes and don't be afraid . There's not much you can do from that screen that's unrecoverable...

thats the same thing with mine, im finding out all the 18.13 are way above what the factory settings are, and the 25.39 are about the same. Kinda hard to figure it out, when the factory setting are way off and there is no info. out to try to figure it out

thanks, I was told to set the BAR to the optimal pressure, at the factory setting at a specific fps. and the adjust the voltage or pulse to get it right from there. But some have suggsted dropping the BAR to just a few over the minimum and increaseing voltage or pulse. Shouldnt 1 way be the correct way ?

 

[Arzrover]

As with everything airguns, there are tradeoffs. Some may not be noticed or noticed immediately anyway.
If you're hunting or obsessing about first shot velocity, setting the reg just above the minimum required to achieve that velocity will eliminate or drastically reduce first shot after sitting being slow. If it's not SO important that first shot be right on but maybe a little more versatility is what's important... set your reg so that the rifle can give you the max that you're looking for... then lesser powers can be tuned as well. The cost of this versatility is first shot velocity... this is generally where the factory recommends. There's a table loaded into the rifle for FACTORY sets that is used to set THE STARTING POINT when you input a projectile and velocity. It tunes for the velocity based on what the initial one measures. It is RARELY right on with the first shot. Some have suggested that higher reg pressure can make it more efficient (quieter and more shots per charge)... I've not proven that for myself but you can certainly experiment if you desire...
Even though it's regulated, they still have the capability of measuring the pressure and making adjustments... just like a Red Wolf. As long as the pressure is constant and near the "Optimal", it shouldn't be doing much adjustment.
Hope this all is helpful... there are a good number of threads of this same discussion here on AGN...

Once an Alpha Wolf came to me for fixing it and to get best accuracy.
I couldn't get the best accuracy on Auto mode.

On manual tuning mode, I set pulse and volts and the gun became very accurate and consistant.

But I don't remember the manual settings. Factory settings are NO NO for me.

For me, and I’m not an expert, Factory mode worked to some degree but the first 3-4 shots varied considerably with standard deviations overall for 12 shots above 4.5.

In Advanced mode, my first shot is typically correct, and my standard deviations are below 1.5. My velocity usually varies not more than 3-5 fps. I do not use Factory mode anymore.

My goal was consistency with accuracy, and I was focused on achieving 880 fps which according to what I’ve read is in the ballpark for the optimum velocity for the pellet. That is not to state that 980 fps might also be effective per the pre-programmed Advanced mode. My Alpha is also now quieter.

Again I cannot conclude based on my limited experience, that I’ve optimized it. Hope this helps.

My issue is, that in advanced mode I have been told to set BAR pressures to optimal, and also to a few above minimum and the adjust voltage and or dwell to get it right.
There is a big difference from optimal to a few above minimum BAR setting. Shouldn't one be better than the other, or shouldn't one be the correct way. In my black and white mind, it's making no sense.
I have emailed Daystate and will post their reply, thanks for the replies.

I would suggest to experiment various settings of all variables.
