    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

    No....they are in equivalence ratio (EQ) which is the compliment of lambda. To convert to lambda, it's 1/EQ. And you can even convert lambda to EQ with 1/Lambda.

    Thank you...

    PE EQ ratio IS the inverse of lambda.. there's nothing different there.
    Post a log and tune if you want help
