Luke,
Slow down there cowboy.
If you plan on bypassing Lambda Sensor fitment [run open loop] via TuneBoy you would be well advised to remove the assembly @ wiring loom connector.
Having the Lambda Sensor in the exhaust without heater power (unplugged) will trash the sensor in seconds.
Leaving the sensor plugged-in and not in exhaust is just plain dangerous and unnecessary.
With Lambda Sensor heater power applied (plugged-in) the sensor tip does get hot and set you and your beloved Rocket on fire.
Hope this helps..........
Gary
