    Getting Aem to read afr error MPVI3 with prolink

    I am working with a P01 PCM. I have an MPVI3 and PRO-LINK. I also have an AEM 30-0300. I have wired the AEM to the Pro-link correctly. I loaded the channel in the channel list correctly. I transformed the AEM read out correctly. I can scan the wideband in the channels list correctly and that part all works fine. The problem I am having is that when I try to "build" a graph to read AFR error, I can not figure out the math parameters for that. I will include my log file so it can be seen and maybe some of you know how to help me. I have looked everywhere i can think of to find the answer and decided to finally ask for help after 3 days of frustration.SKETCH FIRST DRIVE ON NEW ENGINE.hpl

    You're missing AFR commanded is why. Nothing to compare to.
