Hewlett-Packard laser and inkjet printers and Epson inkjet printers. We recommend using a color inkjet printer.

SOFTWARE INSTALLATION

The software is supplied on CDROM media or in the form of a compressed file downloaded from our website. The installation process uses InstallShield. This industry standard installer is based the new Microsoft Windows Installer service that greatly reduces potential problems such as version conflicts and allows for application self-repair. Since Windows 98 systems did not originally include the Windows Installer service, the required installer software is included in the distribution media.

Before proceeding with installation, shutdown any other applications that may be running. For Windows Vista, you must disable the User Account Control (UAC) during installation. If you are not familiar with the UAC, please refer to the Vista UAC Tech Note on our website's Tech FAQ for details.

Use the Windows Explorer or the Run command from the Windows Start Menu to launch setup.exe in the TCFI_Log folder on the CDROM or the setup.exe file downloaded from our website. InstallShield will install the software in an appropriate folder under Program Files.

Once InstallShield has completed the installation, TCFI Log will appear on the Windows Start Menu. You can then launch it just as you would any other Windows program.

TCFI Log requires the Monospace 821 BT fixed pitch printer font in order to properly align columns when printing. The Monospace 821 BT font is included in the distribution media and automatically copied to your Windows Fonts folder during installation. A backup copy is also placed in the program folder. If you accidentally delete this font, use the Install New Font command from the Fonts folder File menu. The filename associated with Monospace 821 BT is monos.ttf.

TCFI CONNECTION

If you are using the new USB Interface, refer to the supplied instructions for details. No additional hardware is required.

If you are using the original RS-232 PC link cable, connect the cable to the OE data link connector and PC serial port. The OE data link uses a four terminal Deutsch connector that is usually found near the TCFI unit.

Turn the ignition key and engine run/stop switches on to provide power to the TCFI unit. Do not start the engine if you want to download data.

If the TCFI unit has been removed from the motorcycle, you can do bench top programming by using an adapter harness (P/N TCFI-ADAPT) that includes a small 12 volt DC power supply.

COM1 is used as the default port. If you are using a different COM port, use the Port Setup command on the Communications Menu.

REAL TIME ENGINE DATA DISPLAY

When the engine is running, you can display real time engine data on an instrument panel type screen by using the View Real Time Data command on the View menu. Please note that real time engine data cannot be directly saved by means of the TCFI Log program. However, this data is constantly being logged by the TCFI unit and can be downloaded (for example at the end of series of dyno runs).

Real time engine data is displayed on an instrument panel type layout with round tach and speedometer gauges and bar graph type gauges for most other parameters. Barometric pressure (In-Hg), any diagnostic codes, status of the user output, and status messages are displayed in additional windows. If the engine is not running most values will appear as zero.

Displayed parameters include:

RPM – engine crankshaft RPM (numeric value displayed beneath gauge)

VSS – vehicle speed in MPH (numeric value displayed beneath gauge)

TPS – throttle position (0 to 100%)

MAP – manifold pressure in In-Hg (29.92 In-Hg corresponds to atmospheric pressure)

ET – engine cylinder head temperature (deg C)

IAT – intake air temperature (deg C)

BAT – battery voltage

IAC – idle air control stepper motor position (higher number means more idle air)
