correct - i think it needs to be a 45 degree angle or thereabouts for best results. O2 Sensor by Rob E, on Flickr Oxygen Sensor Installation Issues (Tech Edge) (wbo2.com)
Mine was slightly more vertical than yours, you can see better on here. The VS position is horizontal and fine. Go figure! Perhaps the fitting I used to get it a bit out of blocking the tailpipe made it too cool, I think it's possibly intended for a header.
There is a minimum distance it needs to be from tailpipe. Need calibration And they don’t like moisture
Modern wideband sensors dont need calibration. My sensor is upright in the collector of a stainless single quiet pack . They last about 50k miles , die covered in soot or if water hits the 600 degrees C heated sensor, or if you smash it fitting or removing the engine with exhaust in place.
That is the Innovate software. PLX Devices digital sensors do not need calibration messing around. Neither do 100% of production cars that use the same five wire wideband sensors, they work with the built in atmosphere sensor fed from the loose cable sleeving going to the sensor that provides the oxygen reference 100% of the time. It's the one (probably relic )software misfeature that put me off going Innovate for a permanent installation. They probably lost the software guy who did some clever work originally, and now they can only bolt different displays around the "magic" source code. Also I expect now that it is "traditional" for aftermarket AFR meters to require calibration, so one that does not must be worse in the eyes of a typical USA customer.
