In this old thread from may: https://www.airgunnation.com/topic/impact-m3-first-regulator-issues/
...there was discussion on the first reg washer stack. FX support said ()()()()(). Member @weatherby successfully used )) (()) (()) ( , but needed extra washers. Very recently in the AEAC RMAC video, one competitor said he worked with Ernest and found a better stack. Also there were some competitors using very low delta between regs of like 10-20bar. I fully expect new things have been learned about this system since launch.
What I'm really chasing is fine tuning the air system to slow down reg creep while maintaining or tightening shot consistency. My first reg is set to 150 bar but can swing by about +-18 bar in operation. My second reg is set to 95 bar and velocity is set to 96.4% of max . My last 23 shot string when the gun was cooled down with some starting shots, was ES 8, SD 3, so pretty good when it isn't sitting around.
After sitting for an hour, the second reg creeps by about 1-2 bar and my first shot is 10-12fps slow. Usually 1-2 shots are needed before the gun is settled in. After sitting for 12 hours, the second reg will have creeped up to 5 bar total, so the reg creep appears to have an exponential decay component to it. First shot after sitting 12 hours is about 30fps slower and 4-6 shots are needed to settle the gun in.
From my searching and reading, reg creeping 5 bars overnight is fairly normal. Ex: one member explained that his FX regulator creeped 10 bar overnight, so he replaced it with a Huma and that creeped 5 bars.
What I'm thinking is that if that first reg can be tightened up so that it is performing better and with less swing, that the delta between regs can be dropped which may slow normal second reg creep. I am not sure what effect this will have on the second reg performance, though. Slower fill? Less or more consistent?
We're living in the worst possible ammo supply times to get to the bottom of such things, so hoping to narrow testing down with community feedback on this.
