I just found the cheat sheet on ROF for the Ion, http://www.techtpain...at%20Sheet.html

Basically, here's how to find your rate of fire. I learned how to do this with a little internet research back when I got my Ion. To determine your ROF, you have to match your dwell setting to its value in milliseconds, then add it to your recharge value in milliseconds. Then, you divide 1000 milliseconds by the number you just got by adding your dwell and your recharge.

So here's what I found. My dwell is at 15, and my rechage is at 10.
Dwl. at 15: 15.76 ms
Rch. at 10: 31.1 ms
15.76+31.1=46.86
1000/46.86=21.34

21 bps! That's what my Ion would be shooting if the board wasn't capped. So now, I could technically to raise my recharge to 33 (42.9 ms) and still be shooting 17 bps. I found this to be pretty interesting; instead of the board setting giving you a direct rate of fire to choose from, you actually have to divide one second (1000 milliseconds) by your cycle time (dwell+recharge), to determine your rate of fire.

So this is where the link and the chart come in (Skip to here for anybody who does not care about math. If this is the case, you can leave now. There's nothing to see here. ;) ) This chart really helps you determine your rate of fire, because instead of doing all of that math, you can just refer to the chart. This also helps because finding your dwell and recharge settings in terms of milliseconds is complicated, too.

For dwell, 0=8.08 ms, and every next setting adds approximately .5-.53 ms.
For recharge, 0=26 ms, and every next setting adds approximately .5-.53 ms.

It is very helpful if you own a stock board. Aftermarket boards use different settings, so this will only work for the stock Ion board. I am posting this so Ion/SP8 owners can determine their ROF, or to help them better understand their marker.

Nice info, just pretty old. Thanks for taking the time to post though.

I just recorded my shots on the computer through a mic, saw the sound waves, and counted the # of shots within a sec

Ah, the fancy road. lol jk. I don't have goldwave or a mic, so I have to use this equation. I haven't seen it anywhere on this site, so I posted it. The main reason for the post is the chart though. It's like the bible of Ion tuning for me. It's the only way I can find my ROF.

Of course by now, I have made my own chart in Excel that has 5 different rates of fire, and different Dwell/Recharge combos for each number. I might add that tomorrow. A lot of people don't have goldwave or a chrono, so it would be useful information.

No, it's capped at 17. But theoretically, the Ion is capable of achieving up to 24 bps timing-wise, because the marker will still fire with dwell as low as 12, and the recharge at 0. Your cycle time would actually be short enough to were you could fit 24 cycles into a one second time period. But, unfortunately, that bolt will never move more than 17 times in one second until you upgrade the board. :(

i believe this will work for the blackheart board as i'm pretty sure it uses the same setting system.

There is also a calculator here:
http://www.warpig.com/paintball/technical/...parts/ion_calc/

Interesting that the TechT chart says 5.53ms increase per step, when Smart Parts chart (they have one in the Epiphany manual and the new Ion manual) says 0.5

Actually, both of those are wrong. I don't know why Smart Parts did this, but it changes for different settings. I guess since they already invented the most complicated board out there, they wanted insurance, so they made it more complicated :laugh:

EXAMPLES
Dwell
Increase from 0-1: 8.08ms to 8.59ms= .51ms

Increase from 12-13: 14.22ms to 14.74ms= .52ms

I guess that .01 milliseconds won't make a very large difference, just remember that at 17bps, that adds up to .17ms. :laugh: I guess it isn't that important, but it's still not the professional way to do it.

What did you use to measure that?

The chart shows it. Also, you can use mathematics and an accurate chrono to prove the digits, but they might interchange (dwell/recharge). You can use the chart, enter the setings, and use an accurate chrono and see if the chart is accurate. I have tried 6 or 7 settings, and it was dead on every time, so I trust that chart a lot.

Actually all that tells you is how fast the board can fire, not the marker, if you want to know how fast you're shooting by a mic for your pc and use the recorded that comes with Windows.

Thanks, thats a good idea. I have a mic somewhere in the attic, I just have to go and find it. If that works, I will probably do that from now on, just gotta make sure the 'rents aren't home :P

Yeah, this is old info, and it was determined along time ago that it was false info. The board is capped at 17 bps. Good luck getting anything more out of it.
