SMART 75 Shift Box - Product Support Page
Last updated 1/25/17


Forced Four SMART 75
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 75 must be properly configured for your transmission type before operating

  • Mount the SMART 75 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 75 shift box:
Any wires not used should be capped to prevent damage or unwanted behavior!

USB type mini connector

        Use of a USB cable with a mini connector is necessary to connect to your pc or tablet

 

Display 8 pin connector

  • SMART handheld, SMART display, or SMART gauge simply plug into the display connector

 

Main 8 pin connector [power, output, and input]

  • Red wire is +12 volt power from the ignition switch or TCU fuse (18VDC max)

  • Black wire is ground, connect to a good clean chassis ground

  • Yellow wire goes to Shift Solenoid A (SOL-A) (3A max)

  • Brown wire goes to Shift Solenoid B (SOL-B) (3A max)

  • Green wire goes to Shift Solenoid C OR Lockup Converter (SOL-C) (3A max)

  • Purple wire is Digital Input #1 (DI1) configured as up shift button by default, active when grounded

  • White/Purple wire is Digital Input #2 (DI2) configured as down shift button by default, active when grounded

  • White wire is Digital Pulse Input #1 (DPI1) configured as the RPM input / tachometer signal input

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 2nd 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.

  • 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.

  • The torque converter lock-up feature, when enabled, will illuminate the green LED when the solenoid is turned on

  • 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 75 is updated instantly. 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.
