I have set up my wide band through the egr and it is working as it should, showing on the chart vs time. I have tried to set up a graph for egr error and the it is bouncing around the cells as though it is set up right but it does not record any data. I will attach pics of all the settings and math I have done. I have watched numerous videos on this and believe I am doing it right. Can some one see where I have made a mistake?afr err.PNG
