Your AFR/Lambda units are all screwed up......For Lambda you need to start with Equivalence Ratio Commanded in channel (OK). Add that to your Chart. Then you need the wide-band. The WB EGR.xml you sent is for AFR, not Lambda. I hve included an updated version called WB EGR Lam.xml. The WB EGR Err is also for AFR so I updated to perform in Lambda, called WB EGR Lam Err. Also updated the Chart with these changes. You will have to reload the math parameters from your locations
