In simple terms it proves the Broad Band sensor, used as it is today, is NO better than reading the stock Narrow Band sensors.
How exactly does this prove that? That broad bands are no better than narrow bands? You have often posted that the broad bands come with in accuracies, but where is the data to support the narrow band equivalency statement?
I know based on the testing I have done comparing lambda based narrow band calculated ve cells in heavier load ranges to those same cells being measured by broad band sensors, the reported values from the broad bands were outside the range that you suggested as the accuracy of the broad bands. I also know that when moving the ve table values based on the broad band readings the torque line reacted favorably. This leads me to believe that the broad band readings are better than narrow band readings in the heavier load cells.
This isn’t a cut on using stock narrow bands. I have no issues with using narrow band sensors in some light load and cruise ranges, but I prefer broad band sensors at richer settings for heavier load areas. I think that narrow bands should be used in any areas that will be running in closed loop.
Funny how I've been telling people this for years and you have been part of the discussions in the past, so your well aware of what I've said. While I did state the range was about 1 AFR error and the chart clearly shows 0.72 AFR you need to remember the temperature error is not shown on the chart.
I’m aware, but you and I seem to always disagree on what the data means.
I’m not at all alarmed by the potential for pressure and temperature error. Perhaps the target value and natural allowable margin of error of the target afr plays into my favor, which is why I haven’t seen the negative accuracy results of using broad bands. I really wish you would develop a scalable analog input into the Data Master program to incorporate broad bands into your system. To me, if you did that your system would eliminate the need to use a secondary data collection and software option. I see this as a huge potential for you.
