I found this, seems pretty simple...
#26 Smallies' Guide to fixing FSDO with an LPR
This guide to fixing First Shot Drop Off (FSDO) is for people who have solenoid related FSDO only. That is, their hammer assembly and solenoid are both properly lubed, however their board is just not supplying enough power to operate the solenoid properly at a low dwell setting. If yours aren't properly lubed, go read the guides to find out how to properly lube both of them.
Set your dwell to zero. Put your LPR at maximum pressure. Set operating pressure to 160psi.
Shoot your gun. If it has FSDO, raise the dwell 5 beeps. Wait 5 minutes. Shoot, if it has FSDO, raise 5 dwell beeps, wait 5 minutes. And keep doing this until FSDO goes away.
Once it goes away, lower the dwell 1 beep, wait 5 minutes, and shoot. Keep repeating this until FSDO comes back. Once it comes back, raise the dwell 1 beep. FSDO should be gone now.
Now, adjust your LPR so your gun shoots 280fps. Wait 5 minutes, shoot the gun. If you have FSDO, raise dwell a beep, and compensate by lowering your LPR until it shoots 280fps. Keep repeating this process until you have no FSDO and you're shooting 280fps.
If you find your gun is inconsistent, raise the LPR pressure a tiny bit, back off on your main operating pressure a tiny bit. Keep doing so until the gun is consistent & shoots 280fps. Your dwell should not be changed while doing this.
Now take the back cap off the back of your hammer assembly and using a Q-tip, clean all the lube out of the rear area of the ram. Trust me you'll never see FSDO again, and your gun will be properly lubed.
When you lube your gun, a big wad of the lube ends up in the rear of your hammer assembly and this causes massive FSDO.

#27 Smallies' Guide to fixing FSDO without an LPR
Take the back cap off your ram, clean out ALL lube you see. Move the hammer/ram forward and use a Q-tip to remove ALL lube out of the hole where the ram is... now put the cap back on. Do NOT re-lube your imp.
Cycle the ram 10-20 times with your finger (by pushing on the pin obviously), gas up your gun, shoot. If it has FSDO still, its solenoid related.
If FSDO is gone, your FSDO was hammer assembly related and is now gone.
If its still there, clean your solenoid. Then raise your dwell a few beeps (2-3 beeps), lower operating pressure until you shoot 280. Wait 5 minutes. Shoot. If its still there, raise dwell again, lower op. pressure, until u shoot 280. Wait 5 min, shoot. Repeat this process until FSDO is gone.
One other thing:
In the future, when you lube your pulse, lube the o-rings on the hammer assembly and then put a little lube into each of the holes on the hammer assembly.
Shoot the gun 50 times or so with air to cycle the lube through your gun.
Now take the back cap off the back of your hammer assembly and using a Q-tip, clean all the lube out of the rear area of the ram. Trust me you'll never see FSDO again, and your gun will be properly lubed.
