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 the menu below to change this, or disable the downshift protection.
  • Note that the shifts are made at full line pressure by default, so learning the timing on when to make the shift will make using this shift box much more pleasurable on the street.
  • The "soft shift" feature can be turned on using the menu, see below. By default this feature is disabled, and when enabled is only used for downshifts at this time. A firmware update may add more features in the future. Please note that the downshifts may still be quite firm depending on the timing the shifts are made, and you must practice to learn when to make smooth shifts.
  • 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.

Using the menu:

  •  To enter the menu, downshift to first gear using the down-shift button. Press and continue to hold the down-shift button for ~ 5 seconds, until the menu pops up.
  • To select, toggle, or advance a value press the up-shift button
  • To save and move on to the next menu option press the down-shift button
  • To exit the menu at any time just wait ~ 5 seconds without pressing any buttons, or continue to press the down-shift button until you find 'save & exit menu'
  • Follow the on screen instructions to finish the setup of your shift box

Configuring the Programmable up-shifts:

  •  Configure the up-shift RPM to be at least 500-1000RPM sooner than your desired shift point. Due to the lag inside the transmission, some trial and error testing will be needed. Start on the safe side and slowly increase the RPM's until you reach your desired shift point.

  • You must configure the delay that it takes for the gear to change and the engine speed to be pulled down below the next shift point. If this delay is not long enough, you will notice double shifts. By default this is set to 750ms and this should suffice in most applications.

  • Finally you must enable the RPM up-shifter in the enable/disable menu option.


Testing the downshift protection:

  •   By default the engine RPM is displayed in cell 2 to verify correct engine RPM. If it is not displayed, In the menu, select display engine RPM on one of the user configurable cells to display on the home screen to verify correct engine RPM.

Testing the TPS input:

  •  By default the TPS value is displayed in cell 3 to verify proper TPS operation. If it is not displayed, In the menu, select display throttle position sensor value on one of the user configurable cells to display on the home screen to verify correct throttle position configuration. Note the value may not be exact with your ECMLink datalogs, this is to be expected.
