Basic instructions:

  • Once installed, this shift box is simple to use. Simply press the up-shift button to advance to the next gear, or press the down-shift button to drop to a lower gear.
  • This shift box will boot up in 3rd gear every time as a safety in case the shift box would ever reboot due to a power connection problem.
  • By default the downshift protection RPM is 4500RPM, see below to change this, or disable the downshift protection.
  • Note that the shifts are made at full line pressure, so learning the timing on when to make the shift will make using this shift box much more pleasurable on the street.
  • Note that the transmission has a delay of 500ms-1000ms for the actual shift to complete. This will vary some with engine speed and power level, and transmission adjustments. Be sure to shift early until you learn how long your transmission takes to perform the shift at WOT to prevent a possible over-rev of the engine.

Configuring downshift protection:

  • To adjust the downshift protection RPM you will need to open the cover to the shift box enclosure. On the inside is a small dial with the numbers 0-7 on it. See the image below for the exact location if the dial. Using a small screw driver turn the dial until the desired selection is made. The default position is #3 which is 4500RPM.
  • 0=off
  • 1=3500RPM
  • 2=4000RPM
  • 3=4500RPM (default)
  • 4=5000RPM
  • 5=5500RPM
  • 6=6000RPM
  • 7=6500RPM

Testing the downshift protection:

  • On the inside of the shift box is a yellow/orange LED. This LED does a bulb test when the shift box is first powered up. See image below for an exact location of the LED.
  • This LED is used to indicate the downshift protection is working. When the engine RPM's are brought up above the set RPM, the LED will turn on. When the RPM's drop below the set RPM the led will turn off.
  • Note some flicker on this LED is normal, especially when near the set RPM due to timing belt flex and noise. If excessive, this may indicate your cam or crank angle sensor needs to be replaced.

Updating the firmware:

  • The most recent Shift Box LITE firmware version is 001
  • Please send an e-mail to sales@forcedfour.com to inquire about updating your firmware. Please note this shift box does not support USB firmware updates and will need to be shipped to Forced Four to be updated.
  • (Note: All settings will be set to factory defaults when the firmware is updated)
