I just purchased and installed a Spartan 2 WB02. Previously I was use an AEM UEGO that I was borrowing from a friend. I am not sure how the AFR value is actually calculated for logging in the ADX? I am using a mildly modified "Advanced $OE TP5 v250" and it uses the formula X * 0.039063 + 10.000000 to arrive at its result but I have no idea for which type of sensor that was adjusted for or how to tweak it for mine. Can anyone shed some light on this for me?
