Just a follow up on my adventures tuning my Heliboard equipped Daystate Redwolf .22 HP.
As stated in my previous post, the actual tuning process as I understand it, is reasonably straight forward. Although never explained in detail anywhere, the essential concept of doing so is as follows.
The Heliboard uses 20 SET-R values which correlate to air power (BAR). Each of these effects a range of shots both above and below their set value (about 8-9 total/approximately 4 above & 4 below). Each shot has an individual R value within one of the 20 SET R-value ranges. For instance if you happen to be around 230bar your R-value may be around 859 which falls about midway into the 840 R-SET. So, if your gun is shooting lets say 925fps at an R-value of 859, you would adjust the current voltage of your guns 840 R-SET in order to raise or lower your speed.
That's really all there is to it. I'm not going to get into HOW to do that, there are a couple of good YouTube videos on the actual process. So, to sum up, it's the voltage of any particular R-SET that regulates the speed at which you'll shoot while your gun is within that R-SETs range. There are two tables below. The first (larger one) is a before adjustment reflection of how the gun is shooting from a full fill of 250 bar (about 919R) down to 160 bar (about 560R). The shot string is divided into 4 colored columns. Beginning with the 4 on the left, running vertically top to bottom then returning to the top, middle four again running top to bottom and finishing with the right most colored 4. The 5th uncolored column at the right of each of the colored columns is labeled +/- and designates the amount the voltage that R-value needs to be lowered or raised to achieve any given change in fps. Volts tend to have approximately a 1.5 volt to 1 fps relational value. So, if you want to lower your speed by 10 FPS you'll need to drop your voltage by 15 volts and vice versa.
Now that's the simple part. What follows next is a bit more complicated. Because there are 8 to 9 shots within every adjustable voltage range, in order to make the best possible overall adjustment you must find the average FPS of all the shots within the range. By adding all the FPS numbers within that range together, then dividing the total by however many entries (8 or 9) you used, you'll get a mien average FPS for the entire range. You can then use that fps as your basis for adjusting up or down to your desired fps.
Since all guns have an optimal power range (BAR) in which they perform most consistently, any of the R-SET values outside of that range (above or below) should be set to the highest or lowest (depending on what end of the range you're attempting to influence) effective value.
