Anyone used this? having a problem with it atm, I've tried calibrating it twice now.
With the sensor out of the exhaust it takes readings and the green light stays solid, with it in the exhaust it doesn't and the green light just constantly flashes green
car no longer has a cat, this wouldn't effect the sensor taking readings surely?
