Forced Four SMART 50
INSTALLATION INSTRUCTIONS

• If used with a TCU or other method of controlling the transmission, only one way of controlling the transmission should be powered on at one time to prevent unexpected control of the transmission or damage to the TCU. Use of our TCU package or similar suitable switch/relay must be used to power the TCU or shift box one at a time.
• Use of diodes, provided with the TCU package, is necessary to prevent damage to TCU.
• The SMART 50 must be properly configured for your transmission type before operating
• Install the SMART 50 unit in the vehicle cabin away from heat and moisture, routing wires away from a CDI ignition box or high voltage coil wiring recommended to prevent erratic behavior.

Wiring the SMART 50 shift box:
Any wires not used should be capped to prevent damage or unwanted behavior!

GENERAL USAGE 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, unless configured differently by the user, 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.
• TCU mode will be active by default with DI4 input grounded, if not in limp mode or disabled by user, when a manual shift is made you must disable and re-enable TCU mode to make active again.
• Solenoid C by default is used for soft shift function, soft shift must be disabled to use as shift solenoid or lockup.
• TPS and speed signal inputs required for TCU mode to be active.
• Brake switch and engine speed inputs recommended for most applications.
• TPS must be calibrated to prevent out of range error codes which may cause limp mode.
• Speed signal pulse per mile (PPM) must be properly set for accurate speed measurement.
• Engine speed pulse per revolution (PPR) must be properly set for accurate engine speed measurement.
• Digital inputs may be configured for your purpose, inputs are active when pulled low to ground
• To use the RPM up-shift feature, you must set the shift points to your desired RPM in the menu. Set the shift point ~1000RPM sooner than you want the shift to be made to start, and adjust as necessary. This is due to the delay inside the transmission to engage the clutches. You must enable the UP-SHIFTER in the menu to use this feature.
• The overdrive off feature can be used by up-shifting to overdrive gear. Press and hold the up button until the O/D off LED illuminates and the shift box downshifts to the next lower gear. To turn O/D back on, up-shift to the max gear and press and hold the up button until the O/D off LED turns off and the shift box up-shifts to overdrive gear.
• Click on the question mark for helpful hints on each application tab page.
• Note that the shifts are made at full line pressure, learning the timing on when to make the shift will make using this shift box much more pleasurable on the street.
• Download and install the PC app from our website, www.forcedfour.com/downloads.htm driver installation may be necessary. Connect the USB cable to your PC and turn on the shift box before launching the PC app. Select the com port and press connect.
• As you make your changes on the PC app the SMART 50 is updated instantly when you press the enter key. Changes are not saved permanently to the flash memory though until you press the save changes button on the connect tab. If you fail to save changes, the settings will be reverted back after a power cycle.
