Here are the dipswitch settings for the LED Matrix. You need to determine whether you have a Gun 12 chip (standard) or the Gun 20 (enhanced). I cannot tell you how to figure that out, but once you do, this is the dipswitch chart. The "d" and "u" represent down and up, respectively. Forward is the bolt forward time, expressed in milliseconds. Back is the bolt back time, expressed in milliseconds. The Forward time also corresponds to the dwell. If you are having difficulty feeding before the bolt closes, increase the "back" time. This also gives more time for the valve to recharge. Increasing "forward" will raise the velocity, of course, so don't forget to re-chrono. Also, don't forget to get air more often as your efficiency will suffer. Lower forward time requires a better lubed bolt, so be consciencious if you want that speed.
