5.0 Main Menu

There are six drop down menus at the top of the T-Com™ WP interface.

5.1 File Menu

Provides access to save or load files.

5.1.1 Read All Tables from a File

Permits the retrieval of previously stored calibration data from a disc file. T-Com™ WP uses the .TCT file extension for calibration files. (The hot key for this operation is F11.) Note: When working Off-Line, a calibration file must be loaded before any configuration tables can be viewed.

5.1.2 Save All Tables to a File

Permits storage of calibration data to a disc file. (The hot key for this operation is F12.)

5.1.3 Dashboard Setup

To assist the user in calibration and monitoring, an array of sensors is available for display in any of the dashboards. All of the sensors have pre-programmed warning limits that will change the color of the sensor reading when the value exceeds these limits. Sensors are selected when editing a dashboard or when selecting an auto-trigger for data-logging.

The Edit Dashboards interface permits up to 15 custom dashboards to be configured in addition to the Global Dashboard, which, by default, contains all the available sensors. Simply highlight the desired sensor/sensors and click the Add button to place those sensors on the dashboard. Note: For best performance, keep the number of displayed sensors at 14 or less. When more than 14 are displayed, the data update rate decreases.

The name of each dashboard can also be customized by selecting the desired dash and clicking the Edit button.

5.1.4 Custom Colors

Permits the colors used for tables and to represent data to be customized. Simply double-click the color box beside the desired parameter, select a color and click OK.

5.2 View Menu

Provides access to the various system configuration options and transmission operational parameters.

5.2.1 System Configuration

5.2.1.1 Operational Parameters

There are four discreet parameters that must be entered first in the Operational Parameters menu in order to properly configure the TCU for your application. These are Rear Tire Diameter, Rear Gear Ratio, Number of (engine) Cylinders and select the correct transmission being used. Note: It is also highly recommended to set your TPS parameters before test driving the vehicle.

These parameters and the others in this menu are manipulated as follows.

5.2.1.1.1 Rear Tire Dia. (inches)

Allowable Limits: 12.0 - 35.0 inches

Enter the actual rear tire diameter (not wheel size) in inches. Used to accurately determine vehicle speed.

Use the handy calculator below by simply entering the numbers from your tire's sidewall. The example numbers would be for a P255/60R16 tire.

5.2.1.1.2 WOT Minimum Shift Time (sec.)

Allowable Limits: 0.0 - 25.0 seconds

Contains a default setting; no need to change. Must be set to a minimum of 0.5 seconds. Allows for time delay from shift signal to actual shift by transmission to avoid stacked shifts.

5.2.1.1.3 Part Throttle Shift Time (sec.)

Allowable Limits: 0.0 - 25.0 seconds

Contains a default setting; no need to change. Must be set to a minimum of 0.5 seconds. Allows for time delay from shift signal to actual shift by transmission to avoid stacked shifts.

5.2.1.1.4 Minimum TPS for WOT (%)

Allowable Limits: 50 - 100%

While this parameter contains a default setting, it's best to adjust this for your application. Determines what throttle position the TCU interprets as Wide Open Throttle to place the shift timing to RPM control. With the ignition on, key off, depress the accelerator to WOT and note the TPS reading on the dashboard. It's recommended that this parameter be set a couple percentage points below actual WOT. Example: The dashboard shows TPS at 85% at WOT. Enter 83% in this parameter.

5.2.1.1.5 Maximum TPS for Idle (%)

Allowable Limits: 0 - 100%

While this parameter contains a default setting, it's best to adjust this for your application. With the ignition on, key off, note the TPS reading on the dashboard. It's recommended that this parameter be set a couple percentage points higher than actual idle position. Example: The dashboard shows TPS at 17% at idle. Enter 19% in this parameter. Note: This affects TCC Lock-up operation at idle. Also, the TCU will interpolate between your idle TPS setting and WOT TPS setting so that the part throttle shift schedule (TPS vs. MPH) can be determined.

5.2.1.1.6 Downshift Hysteresis (MPH)

Allowable Limits: 0 - 25 MPH

Contains a default setting; no need to change. This figure is the difference in upshift to downshift mph during part throttle driving; e.g., if the 2nd gear upshift occurs at 20 mph, then a downshift will not occur until the vehicle mph falls below 15 if this is set to 5 MPH. This is to prevent gear 'hunting' or busyness.

5.2.1.1.7 Drive Gear(Speedometer)

Ford Applications Only: Enter the number of teeth on the transmission output shaft that drive the speedometer driven gear. The VSS is used to accurately determine vehicle speed for part throttle shift scheduling.

5.2.1.1.8 Driven Gear(Speedometer)

Ford Applications Only: Enter the number of teeth on the speedometer driven gear that engages the output shaft. The VSS is used to accurately determine vehicle speed for part throttle shift scheduling.

5.2.1.1.9 Gear Ratio

Allowable Limits: 1.00 - 7.97

This is the actual rear gear ratio for the vehicle. Used to accurately determine vehicle speed.

5.2.1.1.10 Rev. LP Kick (%)

Allowable Limits: 0 - 25%

Contains a default setting; no need to change. Defines the percentage increase of line pressure when the transmission is in Reverse.

5.2.1.1.11 Econ/Perf LP Kick (%)

Allowable Limits: 0 - 25%

Contains a default setting; no need to change. Defines the increase of line pressure curves when the performance mode is selected in the Econ/Perf wiring option.

5.2.1.1.12 Number of Cylinders (4,6,8)

Allowable Limits: 4, 6 or 8 cylinders only

Enter the number of cylinders in the engine. Used to determine proper engine RPM.

5.2.1.1.13 Radio Buttons (Transmission Type)

Select the appropriate transmission model for your application.

5.2.1.2 Wide Open Throttle Parameters

When the TCU interprets WOT based on the TPS settings (see Part Two-5.2.1.1.4), these shift parameters come into effect.

5.2.1.2.1 Wide Open Throttle Upshift Parameters

Allowable Limits: 0 - 12,750 RPM

In this menu you can enter the RPM that you desire for each gear change independently. You will find three boxes, one for each gear change; (1-2), (2-3) and (3-4).

5.2.1.2.2 Wide Open Throttle Downshift Parameters

Allowable Limits: 0 - 255 MPH

There are also three boxes determining downshifts at WOT. Enter the maximum MPH you desire for a forced downshift to the stated gear. The MPH must be below the specified amount before the transmission will allow downshift to the stated gear. Caution: If set too high for any given gear, you may float the valve springs or hit the engine rev-limiter.

5.2.1.3 TCC Lock-up Parameters

These variables control the torque converter lock-up functions.

5.2.1.3.1 Minimum MPH for TCC Lock-up

Allowable Limits: 10 - 255 MPH

Enter the MPH that you DO NOT want the torque converter lock-up to function below. Example: Entering 45 will prevent the TCC from operating below 45 MPH.

5.2.1.3.2 TCC Lock-up Rate

Allowable Limits: 1 - 255

This function only applies to the 4L80E/4L85E, which is equipped with a pulse-width modulated TCC solenoid. The smaller the number you enter in this field, the longer the amount of time between the solenoid starting to open and being fully open. The smaller the number, the softer the apply feel of the torque converter. Note: Although 1995 & later 4L60E/4L65E transmissions are equipped with a PWM TCC solenoid, it is operated as an on/off solenoid.

5.2.1.3.3 Converter Lock-up Delay (sec.)

Allowable Limits: 0 - 25 seconds

Contains a default setting, no need to change. This provides a time delay between the converter lock-up apply and release. This prevents the torque converter from locking and unlocking in rapid succession, which is known as hunting. Once the torque converter is signaled to unlock, it will not apply lock-up again until the designated number of seconds has elapsed.

5.2.1.3.4 WOT TCC Lock-up

Checking this box enables the TCC to apply at WOT once the specified minimum MPH parameter is satisfied, bypassing any specified time delay. If not checked, the TCC will apply exactly according to all set conditions.

5.2.1.4 Engine Braking Parameters

Contains a default setting, no need to change. This controls line pressure if the transmission is downshifted at too much speed for the selected gear to avoid harsh deceleration.

5.2.1.5 Slapstick Parameters

Used only when the Manual Shift Mode is selected (see Part One-2.2.11).

5.2.1.5.1 Manual Mode Shift Time (sec.)

Contains a default setting, no need to change. Must be set to a minimum of 0.5 seconds. This is a time delay to prevent advancing more than one gear per shift within a set time period. This parameter has a .1 sec. resolution and allows for settings between 0-25.5 seconds.

5.2.1.6 Enable Option File

This is to facilitate upgrades or options to the TCU through a file furnished by the manufacturer.

5.2.2 Force Motor Tables

5.2.2.1 Overview

These tables enable you to edit individual pressure curves for each gear. This allows you to adjust the 'feel' of the shift relative to the TPS position. The number on the Y-axis is the percentage of duty cycle of the pulse-width modulated (PWM) solenoid that controls line pressure. The closer the number is to zero, the higher the line pressure. At zero, the solenoid is not bleeding off any pressure; thus the transmission will be operating at maximum line pressure. Typically, the user will want less line pressure at the lower throttle positions (lower percentage opening). This will provide for a smooth (mild) shift when the vehicle is being driven at an easy throttle position, building to a firmer (harsh) shift as the driver gives the vehicle more and more throttle. It is recommended that you increase the line pressure of he curves when installing torque converters with higher-than-OEM stall speeds.

Caution: Setting duty cycles to minimum line pressures on the force motor tables can result in slipping clutches/bands. Changes in the line pressure tables should be made in small increments to avoid severe transmission damage.

5.2.2.2 Example of Force Motor Table

5.2.3 Part Throttle Shift Table

5.2.3.1 Overview

This table controls what gear the transmission is in at any given time as long as the TPS position is lower than the percentage designated as WOT (see Part Two-5.2.1.1.4). Decisions are a function of TPS position and road speed. Each curve can be edited to adjust the transmission shift timing to the vehicle or driver preference.

5.2.3.2 Editing Part Throttle Shift Points

Use the Tab key to move the cursor to the next curve. The Page Up and Page Down keys (or arrow uparrow down keys) will increase or decrease the upshift MPH for a given throttle position.

The mouse can also be utilized to manipulate the shift timing curves. See Part Two-4.2.2 for more details.

5.2.3.3 T-Com™ Table Tuning Tips

The following types of changes can be made in all graphs. Multiplying, adding, subtracting and forcing values can be accomplished by doing the following.

5.2.3.3.1 Increase/Decrease by Percentage

To multiply by a certain percentage, right click the graph and select Percentage Trim or use the following keystrokes. Hit the Shift and 8 keys simultaneously or *. The program will then prompt you for the percentage change. Example: 100 would represent 100% (no change). For 10% more type 110 or for 10% less, type 90. Then hit the Enter key. This will automatically change the curve/graph.

5.2.3.3.2 Increase by Addition

To add a fixed amount, right click the graph and select Additive Trim or hit the Shift and the + simultaneously. The program will then prompt you for the amount. Enter the number and hit the Enter key to make the change take place.

5.2.3.3.3 Decrease by Subtraction

To subtract a fixed amount, right click the graph and select Additive Trim or hit the Shift and the + simultaneously. The program will then prompt you for the amount. Hit the minus or - key, then the number and hit the Enter key to make the change take place.

5.2.3.3.4 Change by a Forced Value

To force a value, simply type the number, followed by the Enter key.

5.2.3.3.5 Highlight Function
