But this table needs to be set up to log your wideband O2 sensor. So click on the button to the right of #8 "Configure Histograms", rename it to MAF-WB-AFR from MAF-Commanded AFR. Then under plot value, click the PID:<click to insert or change> , now a box appears with the available PIDS. Click on the AUX>wideband O2 and click on the brand of wideband you have. I also set the decimals to 2.
    You also need to log commanded afr low res., maf freq. and your wideband O2 sensor in the table display as well. The help files show were to insert the wideband (EIO input 1) on the right of the table near the bottom. I use a FJO

    by "maf freq" do you mean "Mass Air Flow (SAE)" or "Maf Air Flow (lb/min)" which both should automatically already be on there?
