Hey guys,

I'm just getting into Paintball, but my endless need to tinker has overcome my sensibilities.

I have an older Impulse (non-vision) with a Shocktech Supafly bolt, Shocktech heavy hammer, EVIL LPR, Trinity Feedneck, Freak Barrel kit, and a PE Modified Mag trigger.

I want to refine the trigger/grip assembly, but that's now what my questions are about.

Here are my questions:

1)  I just ordered a WAS board from PBNation.  The previous owner wasn't sure what version it was.  Is there a way to tell?  How do I update it without buying the link cable?

2)  I'm a little nervous about my LPR setup.  The guys at the field recommended it to help improve air efficiency.  My imp (before the LPR) was EATING air like nobodies business.  I had to fill up after ~600 rounds on a 72/3k tank.  They suggested an LPR would help a lot.  Is ONLY swapping in the Evil LPR assembly going to help?  Is it safe to just swap out the LPR?

3)  How do I tune the gun?  You know my basic stats, so how do I best tune it?  I don't have an LP pressure gauge, but it does seem like I get a good bit of FBDO now that the LPR is on.  I know I need to increase dwell, but I don't know how to do that or what it means.

4)  What is the Impulse limited to ROF wise?  Like, in ramping mode on the WAS board, how fast can I really expect the IMP to fire?  I've heard that it is mechanically limited to ~21bps, but I don't know why.

5)  I haven't swapped on the Freak barrels yet (haven't arrived), but with the stock Progressive barrel, the gun seems really inconsistent shot-to-shot in terms of accuracy.  On two trigger pulls, the paint will go drastically different directions.  I'm shooting RPS Nightmare or DXS Blaze (I prefer the blaze.  The RPS doesn't seem to work very well in the woods, where I spend most of my time).  Is there a reason besides the stock barrel?

6)  Are there any other mods you guys could suggest to help improve air efficiency and consistency shot-to-shot?  What about weight saving mods?  This gun seems pretty heavy.

7)  Are there any other "must do" mods you'd recommend?  What will I gain from those?

I know it's a lot of questions, but I really appreciate any help I can get!  This sport is awesome, and for some reason I really like the IMP!

nice work Michael - also - if you DO NOT have the new software for the WAS board a user on this forum (RB211) has it. If you send your board to him he will gladly flash it I am sure. He's cool like that

i'd recommend taking things one step at a time - don't go out an buy a ton of upgrades just yet. Put the LPR on and get the freak barrel setup - see if that helps with accuracy and efficiency and then go from there!

good luck!

what reg are you using?

I'm using a MaxFlo Vertical regulator.

1.  Get the WAS manual and read it well.  Go into programming mode and pull the trigger 6 times.  If the LED isn't alternating orange/green, you have an older board that needs to be flashed to the 2.4 software.  I can flash it if you need it.

2.  LPR's aren't that bad to set up - but as stated, you will need to find the "balance" between LPR, HPR, and dwell.  As every Imp is different tuning wise, you will have to experiment.  Don't expect your shot count to drastically go up - If you want more shots, go up to a 4500psi tank.  3000psi tanks just don't hold as much air.

3.  You are going to get FSDO until you tune the LPR - regardless of what your dwell is.  Increase the pressure on the LPR before you go jacking up your dwell.  7.5ms is a good place to start, increase your LPR until the gun fires consistantly.  Once again - the WAS manual is your friend.

4.  ROF?  That depends on the board you are using.  The WAS is capped at 30, but you will never make it that far.  25-26bps is the best I have ever seen.  Why you say?  The Imp is pneumatically limited to that range.  In other words, some of the internal air passages are too restrictive to be able to handle anything higher.  Can this be remedied?  I don't know.  Widening the air passages going to the solenoid might be able to be done, using larger air fittings and hose between the LPR and solenoid air tube may be possible, but no one has done this to my knowledge - probably due to the possible consequence of screwing the gun up.  I haven't picked up a junk body yet to screw around with.  I might......

5.  Shooting oversize / undersize paint through a fixed bore barrel will mess with accuracy.  However, if you are expecting to put ball on top of ball at 50yds, you are dreaming.  Get a decent barrel, match your paint, and hope for the best.

6.  Mods - Since you are using an Evil LPR, you really need to find an Evil valve.  Evil mods were meant for high pressure use.  For example:  Mixing a Evil LPR with a NDZ RIP valve will increase the aggravation factor in tuning the gun.  The RIP was designed for pressures of 160 and less, the Evil Lpr was designed for pressures higher than that.  Mix finding the correct dwell to that and you will have your hands full.  Weight - Sorry bud, but your stuck with it.  It's an Impulse.  Get rid of the aluminum tank and swithch to a CF tank - that will save you a pretty good chunk.  72/3000's weigh a ton.

I am running evil internals and yes they run higher. I am at 200Psi on HP reg and about 110 or so on the LPR. I like how the gun feels all personal preference, ebay has some valves for 25 bucks shipped other than that good luck they are almost extinct.

sounds like it...

you guys are awesome!
