O2 Sensor Calibrate Idea
Posted: Tue Jun 01, 2010 11:13 am
Perhaps others have had similar idea, on calibration of wide band O2 sensor without removing it from exhaust tract.
I have used a vacume cleaner on the tail pipe, then ensure at least one cylinder has valves on the "rock" (one closing, one opening) and throttle opened. This allows clean air to purge through and past the sensor, then it can be cycled on and calibrated as per wishes.
On my bike I have the sensor just past a divider that goes back to twin outlets, so it has its own built in circuit to provide air regardless of valve positions.
Just a way to save some time.
