Bird bung.

Today’s project of the day was welding an O2 bung into the exhaust of the 2 door bird. I had been running narrowband simulation from my JAW wideband controller, but since the factory sensor mounts into the exhaust manifold which is very short, the sensor was really too close to the head. Supposedly this will shorten the life of the wideband sensor and I’m sure it affects the readings too. I read in the instruction sheets for the AEM widebands (which I am running in the Mustang) that it should be at least 18 inches from the exhaust port. So I added in a new bung further downstream. I replaced the factory narrowband in the manifold location and hooked it back up to the computer and will now see what the wideband reads – it always read pretty rich with the narrow-sim setup.  See picture of: 1. below freezing working conditions, 2. my rust bucket daily driver bird, and 3. new bung welded into the way too small restrictive factory exhaust pipe.
