I'm using pid E67_AFRATIO_DMA for E67 Camaro ZL1 to show the commanded AFR then to find the AFR error and correct it using CALC_BEN1_E67
But in some new 2013 models it seems there is some thing wrong because the commanded AFR shown as 0.28 ?!! while it should be 14.68
attached a log Log_2198.efi
Thanks in advance
