INTRODUCTION
This quick start provides simplified installation instructions for the TCFI6 Fuel Injection Kit and covers most common installations and set ups. Additional tuning may be required. See additional information, instructions, and
Tech Notes which can be found at www.daytona-twintec.com. We strongly encourage you to read that information as this system is a very powerful tool which can be very simple to use provided the installer understands its features and functions.
1. Unpack and verify all components are included.
2. Make note of the motorcycles VIN#. The VIN# MUST BE CORRECT and will be entered in the software later. Remove saddlebags, seat, or other items to gain access to the factory ECM and Data Link Connector.
3. Remove the main fuse but ensure the alarm is deactivated if equipped. This can be easily done by turning the ignition switch on and the run stop switch to run. Turn the ignition switch off and within 5 seconds remove the main system fuse. Remove the factory ECM. For
2008-2009 models utilize the included adapter kit to connect the factory oxygen harnesses to the WEGO. For 2010-2013 the adapters are not required.
4. For 2008-2009 models only, you must access the main ECM connector and remove the factory
wire from Terminal 48. For 2010-2013 models skip this step. Gently pry the tabs on the connector cover to release them from the body. Remove the cover. Cut the factory zip tie from the connector harness. Slide the green retainer from the connector body. Using a pin, remove the factory wire from pin
48 and install the green wire from the adapter harness shown in step 3. Replace zip tie and reinstall cover.

5. Install the WEGO3D unit onto the TCFI controller with the supplied screws. Final routing and securing of the oxygen sensor harnesses can be done at a later time once the sensors are installed in the exhaust pipes.
6. Skip to step 10 for exhausts with 18mm oxygen sensor bungs in the exhaust pipes. Carefully plan the sensor location approx. 2-6” from the exhaust port and use a permanent marker to locate the position where you will drill a hole for your oxygen sensor bungs. If you have free flowing pipes, the closer to the exhaust port, the better. Remove the exhaust from the motorcycle and drill small pilot holes.
8. Using a step bit, drill a 3/4" hole in each pipe.
9. Weld a bung into each pipe. After the pipe has cooled, use an
18x1.5mm tap (standard spark plug tap available at most parts stores) to clean the threads. Reinstall the exhaust system.
10. Locate the front and rear factory oxygen sensor harnesses.
Disconnect the factory oxygen sensors and plug the matching connectors from the WEGO into the factory harnesses. 2008 and 2009
FL models (equipped with factory 18mm oxygen sensors) will require the use of the included adapter harness. Connect the wideband oxygen sensors included in the TCFI kit to the 6 pin connectors in the
WEGO harnesses but do not install the sensors in the pipe at this time.
Connect the four wire Deutsch connector from the WEGO to the factory diagnostic connector. The WEGO harness provides for a new datalink connection so route that harness to an easily accessible location.

11. Reinstall the main fuse.
The WEGO harness with the yellow band is for the front sensor (sensor 1).
The harness without a yellow band is for the rear sensor (sensor 2). Use a permanent marker to mark the sensors front and rear for correct placement after calibration. Hang the sensors away from fuel, oil, or other chemicals.
12. To calibrate the sensors, leave the off/run switch off. Turn the ignition switch on. This will power up the WEGO. The two red LEDs on the WEGO should illuminate. Use a small screwdriver to turn the two trim pot screws gently counter clockwise until they stop. Let the sensors warm up for two minutes. Caution: the sensors will get hot.
13. After two minutes, use a small screwdriver to slowly turn each trim pot screw on the WEGO clockwise until the corresponding LED just starts flashing. This will calibrate your oxygen sensors. Turn off the motorcycle.
After the sensors cool down, you can install them into the exhaust.
Complete install of the WEGO, and secure any wiring appropriately.
14. SOFTWARE INSTALLATION: DO NOT PLUG IN THE USB INTERFACE UNTIL YOU COMPLETE THIS
STEP! Make sure you have the latest software available for the TCFI system. All necessary files can be downloaded from www.daytona-twintec.com. Download and install the latest versions of the following software:
PC Link TCFI
TCFI Log
USB Driver
15. Plug the USB interface into the 4 pin data link connector coming from the WEGO Harness and the USB Cable into your computer.
Make sure the switch on the USB interface is set to the TC88A and All
Others position.

18. Proper operation of the fly by wire system depends on an accurate, repeatable, and in-range TGS and TPS signals and TCA response. You can use the TCFI Log Software to test and diagnose the ETC system without the engine running. After testing, values will need to be recorded and uploaded to the TCFI controller.
The ETC Manual Test Mode command on the communications menu allows you to test the electronic throttle control system without the engine running. Remove the air filter to view the throttle plate. Turn the ignition switch on and the run/stop switch to run. In the TCFI Log software, select Communications, ETC Test Mode, and ETC
Manual Test. In the pop up window, enter “1” to enable ETC manual test mode. You should hear a humming noise coming from the throttle body. Move the throttle back and forth slowly and observe the throttle plate. It should move relative to the twist grip position. Access the same pop up window through the menus and enter “0” to disable. The humming noise from the throttle body should stop. If you observe the above conditions, you are safe to proceed.
