Mike -
Thank you for that detail - it does open up a few other questions so I hope you don't mind - I think it would be beneficial to other new users.
Factory Settings - is there any way to add new ones, or add new projectiles? If not, I can see why most time will be spent in Advanced Mode.
Advanced Mode - how do you select speed? Is this speed set using a combination of Hammer Stroke, voltage and reg pressure?
One more - if you know this. Is the chrono just a chrono or does it feedback into the system. Meaning are the programs static or fluid and self adjusting to get to a specific pressure? I've had a RedWolf in the past, but that didn't have a reg so the MAP was around the input pressure.
First, the chrono only feeds back into the algorithm in the GCU when the gun is in Factory Mode. When in Advanced Mode, the chrono will display speed for each shot, but the gun functions more like the Red Wolf (although a more advanced GCU) and the chrono is display only.
So you need to set the Advanced Mode to three variables. Reg Pressure, Dwell (Hammer duration in micro seconds), and Voltage (Hammer strength). Then so generally if you start with one of the AoA pre-programmed Advanced mode setting, and its CLOSE to what you want, then adjust with Dwell Time. If its more than 5 or 6 FPS from where you want, adjust Voltage. Generally the gun functions best at the lowest pressure that will get you the speed you want with the ammo you want to use. I'd set the variables so you get near where you want to be, with the reg about 160 bar, then lower the reg pressure gradually until the gun will no longer sustain that speed, then bring it up 5 bar from there.
In Factory Mode, the pre set choices are just to get you close. As far as I know you can't add new choices, but you just set it to the closest one to the actual ammo you want to use. The gun will take it from there. So if I were shooting .25 H&N 31 grain, I'd set the Factory mode to .25 cal, 34 grain, 23 inch barrel settings. The GUN (not you) chooses Dwell and Voltage, and your only variable is reg. pressure.
I've also got the best accuracy with lower Dwell and higher Voltage. Kinda like a short hard hammer strike than a long softer hammer strike. And my gun is set about 20 bar higher than the minimum pressure it'll shoot at the power I want because through trial and error, it likes that best. For example, my .25 shoots the King Heavy at 890 fps. Dwell at 3145 micro sec, Voltage at 83.5 vdc, and Reg at 155 bar. Coincidentally, it also shoots the NSA 29 grain HP DB slugs with the same settings at 940 fps, and is VERY accurate with both.
Hope that helps...
Mike
