Frequently asked questions

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. 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.

Refer to the TCFI instructions for details. Call tech support if you need help.
