Forced Four SMART 150 TCM
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 150 must be properly configured for your transmission type before operating
Mount the SMART 150 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 150 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 B connector is necessary to connect to your pc or tablet

SMART2 Expansion Port (8 pin plug)

SMART2 handheld, SMART2 display, or SMART2 gauge simply plug into the expansion port

Main Connection [Power, Inputs, and Outputs] (16 pin plug)

Purple wire is Digital Input #1 (DI1) up-shift button (Active when pulled low to ground)
Orange/Yellow wire is Analog Input #1 (AI1) typically Throttle Position Sensor (TPS) (0-5VDC)
White/Purple wire is Digital Input #2 (DI2) down-shift button (Active when pulled low to ground)
Orange/Brown wire is Analog Input #2 (AI2) (0-5VDC) OR Digital Input #6 (DI6) (Active when pulled low to ground
Gray wire is Digital Input #3 (DI3) brake switch (Active when pulled low to ground)
Pink wire is speed signal input for vehicle speed MPH
White/Gray wire is Digital Input #4 (DI4) (Active when pulled low to ground)
White wire is engine speed input for engine RPM tachometer
Blue wire goes to Shift Solenoid D OR Pressure Control Solenoid (SOL-D) (3A max)

Forced Four SMART 150
GENERAL USAGE INSTRUCTIONS

Once installed, this SMART 150 TCM is simple to use. Install our SMART PC app to configure.
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. When auto TCU mode is active, it will automatically enter the correct gear after boot up depending on driving conditions. Manual mode will require manually down-shifting to desired gear.
By default the downshift protection RPM is 4500RPM.
TCU mode will be active by default, 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.
Economy shift map is used by default, grounding the sport/eco input will enable sport map or using adaptive shifting will automatically switch to sport map when adaptive conditions are met.
Solenoid C by default is used for lockup function, lockup must be disabled to use as shift solenoid.
Solenoid D by default is used for soft shift function, soft shift must be disabled to use as shift solenoid.
TPS and speed signal inputs required for TCU mode to be active.
Brake switch recommended for most applications, by default the digital input for brake switch is active when pulled low to ground, this can be accomplished with a relay. Alternatively you can invert the input on the inputs tab and connect the digital input directly to the 12V brake switch signal. It may be necessary to use a 1K-4.7K ohm resistor on the digital input connected to ground to ensure the input is pulled low when the brake switch isn't active.
TPS must be calibrated for correct operation of TCM auto 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. You can invert the signal on the inputs tab making the input active when pulled high. High is considered over 2.5VDC and the inputs are 12V tolerable so direct connection to inputs like the factory overdrive off switch works just fine. When the signal is inverted a pull down resistor of 1K-4.7K ohm is recommended connected between the digital input and ground. This will guarantee the signal is low when power is removed. The inputs are pulled high to 5V internally through a 10K ohm resistor.
Digital outputs may be configured for your purpose, when active the output will be connected to ground, maximum 500mA current draw, use of a relay is necessary to switch higher current loads.
To use the RPM up-shift feature, you must set the shift points to your desired RPM. 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 RPM-UP-SHIFTER to use this feature.
Overdrive off can be configured to a digital input and connected to the factory overdrive off switch. Using this switch requires a 1K-4.7K ohm resistor connected between digital input and ground to properly pull the signal low when switch is open if the signal is a switched 12V type.

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 150 is updated instantly when you press the enter key. Changes are saved permanently to the flash memory by default, you can change this for faster configuration but changes will be lost at power cycle if you forget to press the save changes button on the connect tab.
Data log files will be saved to c:\ForcedFour\ directory on your PC. Use the Haltech Datalog Viewer or Megasquirt Datalog Viewer or similar universal CSV viewer to view saved SMART datalogs. Download Haltech Datalog Viewer here.

IMPORTANT NOTE:

You may experience issues with the default Windows driver configurations causing application crash or odd behavior with your mouse if you do not turn off ‘Serial Enumerator’ which is typically on by default. We recommend you follow these few simple steps.

1. Plug in the USB cable with the shift box powered down (ignition off)
2. Open Device Manager (Click on start button and type Device Manager then select it)
3. Locate the correct COM port (shown under ports) on the device manager. Right click and select ‘Properties’
4. Click ‘Port Settings’ tab then click ‘Advanced…’ button
5. Un check the ‘Serial Enumerator’ under Miscellaneous Options

That’s it. If you have multiple devices it may be necessary to perform this for each one as the COM port will vary and this change is ONLY for the selected COM port.
