Tried to get a wideband O2 reading today by sticking the sensor in the exhaust outlet but didn’t get a good reading (usually works on cars with more cylinders). I guess the one cylinder sends the exhaust in strong pulses so I need to locate the sensor closer to the engine.

Can I get a reading by welding a bung in the second to last chamber in the muffler?
