TCFI II & VRFI View Software for Palm OS

·  Use Palm OS based handheld organizer (PDA) to view engine parameters on  motorcycles equipped with a Twin Tec TCFI Gen II, Gen III or VRFI fuel injection controller

·  Facilitates initial tuning and diagnostics, especially on motorcycles without a tachometer

· View any three engine parameters logged by the fuel injection  controller, engine status and diagnostic codes 

· Displays status and allows manual override of the user output

· Works on any PDA with Palm OS 3.5 or later (requires serial HotSync cable)

 Typical Twin Cam Handlebar Mounting

Typical V-Rod^TM Handlebar Mounting

You can mount the PDA on a flat surface with Velcro tape or on the handlebars using an appropriate mount as shown above. View software displays three selected engine parameters, the user output status, and engine status. While the program is running, all user interaction is by means of the hard buttons on the case. Stylus taps on the digitizer screen are ignored for maximum immunity from wind buffeting and bug hits. 

You can select from the following list for each of the three engine parameters. An arrow appears to the right of the active parameter. The right button (Memo Pad) moves the arrow between the top, middle, and bottom parameter. The scroll buttons in the center change the selected parameter.

RPM – engine crankshaft RPM

VSS – vehicle speed in MPH

AFR – exhaust gas oxygen sensor based air/fuel ratio (10:1 to 20:1). Separate front and rear AFR display for new systems using dual channel WEGO.

AF CMD – air/fuel ratio command from current AFR table cell.

BLM – block learn multiplier (main fuel table correction factor based on exhaust gas oxygen sensor feedback, shown as percent value from 75-125%). Separate front and rear BLM display for new systems using dual channel WEGO.

TPS – throttle position (0 to 100%)

TPS V – throttle position sensor output from zero to +5 volts. Used for idle TPS adjustment

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

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

BARO – barometric pressure in In-Hg

IAT – intake air temperature (deg C)

ET – engine (cylinder head or coolant) temperature (deg C)

BAT – battery voltage

F INJ – front injector pulse width in milliseconds

R INJ – rear injector pulse width in milliseconds

F ADV – front cylinder ignition advance in degree BTDC

R ADV – rear cylinder ignition advance in degree BTDC

Engine status and diagnostic codes are displayed at the lower right side of the screen. Available data varies with controller version. Refer to instructions for details.

The left button (Date Book) allows you to override the user output. This feature can be used as a diagnostic aid to test accessory systems connected to the user output. Repeatedly pressing the left button cycles between manual on mode (USER MAN ON), manual off mode (USER MAN OFF), and automatic mode (USER AUTO). When you cycle to automatic mode, the display changes back to indicate the actual status of the user output (USER ON or USER OFF) after about 2 seconds as the fuel injection controller regains control.

REQUIREMENTS 

Choice of an appropriate Palm OS PDA depends on the intended application. Newer units such as the Palm M130 feature a color display with backlight that offers great indoors visibility (for example in a dyno test room) but are not suitable for outdoors use in direct sunlight. Older units with monochrome displays such as the Palm V offer the best visibility in direct sunlight. While the Palm V has been out of production for some time, used units are readily available on eBay for under $60.00.

View software runs on PDA units using Palm OS 3.5 or later (an upgrade to OS 4.1 is recommended). To use  View software, you will require two cables: our Palm link cable (P/N PALM-TCFI-C) and a RS-232 serial HotSync cable for your PDA. The Palm link cable has a male 9-pin connector that mates with your HotSync cable and a four terminal Deutsch connector that mates with the data link connector on the H-D^® wiring harness. Please note that the standard PC link cable (P/N TCFI-C) cannot be used because different handshake signal requirements exist for the Palm application. 

The RS-232 serial HotSync cable has a female 9-pin (DB-9) connector that mates with our Palm link cable and the specific connector for your PDA. Please note that USB HotSync cables cannot be used, even with a USB adapter. Most of the RS-232 serial HotSync cables for the Palm series will work OK. Handspring Visor units require signal conditioning electronics in the serial HotSync cable. Thus potential compatibility problems may occur. For the Handspring Visor series, we have tested and approved the Belkin F8R0101 Y-combo Sync Cable. This cable is available direct from Belkin at www.belkin.com. The Auterra website at www.auterraweb.com or www.auterraweb.com/supportedpalms.html lists an extensive cross reference of serial HotSync cables for PALM compatible PDAs including units from Garmin, Handspring, Kyocera, PALM, Samsung, and Sony. In addition to HotSync cables, Auterra also sells an awesome PDA based scan tool for automotive applications. Auterra uses the same type of interface we do, so any PALM compatible units and HotSync cables listed on their website should work OK.

View software is installed using HotSync from the Palm Desktop running on a PC. You must have access to an IBM-compatible PC with Windows and the Palm Desktop for this purpose. HotSync can be done by means of serial (RS-232) or USB cable or cradle. 

DEMO VERSIONS

Two demo versions are available. The first one, TCFI II Demo, is included with TCFI II View software. TCFI II Demo allows you to try the software out on a PDA without a Palm link cable (the standard TCFI II View program exits if it cannot communicate with a TCFI unit).

The second version, TCFI II Demo Emulator, actually emulates a Palm PDA running TCFI II Demo on your Windows PC. You can download the program file (TCFI2_Demo_Emulator.exe) from our website when you click on the link below. After you download the file, double click on it to start the emulator. Use your mouse and left click on the PDA buttons. To stop the emulator, right click with your mouse and then click Exit on the pop-up menu.
