o2 Sensor
I want to install a Wideband AFR gauge to my build but not really sure what to do.When Supercharging a 2zz using a PFC and adding a Wideband AFR gauge, are you using your existing wiring harness and just replacing the sensor or are you doing a fresh install and running the guage on its own? I' sorry if this is a stupid question, ever looked into this until recently.
