the site i use is down at the moment (angel-owners) but when it's up i'll post a link of all the settings that stockholm joy use with their guns, or if you'r going to the 7 man take it to lips and get them to set it up for you
here's the settings that i use
dwell 6.5ms, shot filtering 5%, de-bounce level 1, loader speed 12, ABS 1.25 ms
have a look round this forum, it should answer any other questions you have http://www.angel-owners.com/forumdisplay.php?f=209
yeah the dwell is far too long at that, my gun is set up with the same settings as the joy devision and it works perfectly. but at the end of the day it's down to you
