The settings are programmed into the EPOCH screen and can be adjusted from 10-50 in increments of 1 in program mode. The valve and transfer port are very large relative to other PCP designs. It seems to work well with their valve and flow design. I believe the dwell in this case is how much LP air is let in over time thru the solenoid until the high pressure side over rides it to close the valve. I have also noticed that the LPR will follow the HPR up/down but can also be throttled down or up manually for specific tuning. My question would be if you have a higher LP setting should the dwell be decreased since you don't need as much due air, due to the higher pressure, to open the valve??I would rather say 3 milliseconds
