If you have the Ragnarok the programming instructions are here:
How do I adjust or make custom rapidfire speeds?
User can program speeds from 1.0-99.0 shots per second. First the "tens" digit is programmed, then "ones" digit, then "decimal" digit. Start out by scrolling to the rapidfire mode you want to program. For example if you want to program Rapidfire Mode #2, then go ahead and scroll to Mode #2 (refer to the basic rapidfire instructions to do this).
Next, we must put the controller into programming mode. Hold the mod switch + tap the sync button. Player 3 and Player 4 LED's will blink rapidly. The mod is now in programming mode, and is waiting for you to make a selection. The user must now press one of these buttons to initiate programming of that feature:
- Fire Weapon (right trigger in default button layout) - Program Rapidfire speed
- Melee (right thumbstick in default button layout) - Program Quick scope speed
- Reload (button X in default button layout) - Program Fast Reload delay
- Throw lethal (right bumper in default button layout) - Program Perfact Active Reloads delay
Of course, you want to press your Fire Weapon button to Program Rapidfire speeds.
Once the user has entered rapidfire speed programming, the mod will flash the "tens" digit on Player3 LED. Hold right trigger to increase tens digit, hold left trigger to decrease tens digit. A quick LED flash means digit is "0". Press mod switch to move to next digit.
Mod will flash "ones" digit on Player 4 LED. Hold right trigger to increase ones digit, hold left trigger to decrease ones digit. A quick LED flash means digit is "0". Press mod switch to move to next digit.
Mod will flash "decimal" digit on Player 3/4 LED. Hold right trigger to increase decimal, hold left trigger to decrease decimal. A quick LED flash means decimal is set to 0. Press mod switch to save new speed. Player3/Player4 led flash to confirm saving of new speed.
I programmed a custom speed and now my rapidfire isn't working?
The most common mistake is dialing in a speed that is simply too high. If your rapidfire stops working, you've dialed in a speed that is above the "cap" set by the game developer. A good starting speed for Call of Duty games, for example, is 8.0 shots per second.
