Ive played with my impulse several times and the problem i keep having is that when i go to chrono my velocity is up VERY high. Naturally i first try to make small adjustments to my dwell. Problem is my dwell doesnt show any sort of consistent increasing or lowering of velocity. First i chrono and its at something insane like 335; ok too high then i try turning dwell slightly to right- 325; ok then try a little more; wo back up to 333; ok turn it back to the left 324; little bit more to the left its 317. etc. Bottom line is i cant get it down and the dwell pot switch isnt showing any sort of consistency anyway. All this and my reg is still set down at 150. Its got a normal 20 oz co2 on/off anti siphon etc. whats the matter? Is it a defective board or what? This is really messing with my mind. Someone who thinks they know whats up help me out.

I have a feeling you have a bad dwell pot.

try going all the way clockwaise (about 4 o-clock) and see if you are still shooting in the 300s. If you are, the dwell pot is not working. Unfourtaly we have seen a few of these latly-- See if the place you got it from has a replacement board- or contact Smart Parts to exchange the board.

Which way do you turn the pot switch to increase the velocity?
