[QUOTE="Denver_SVT, post: 16176148, member: 72321"] I am kind of confused right now. What you're saying above that means most of the time at idle and cruise i will multiply the maf by 2.xxx For ex: Measured_afr = 1.088 Target_afr= 1.000 STFT= 1.016 LTFT= 1.008 Going through the math: 1.088 - 1 + 1.016 + 1.008 = 2.112 Is it correct this way? Because even if you have A/F wideband you will get the Actual AF ratio divided by Commanded AF to multiply it to the maf. For examble at idle: Actual AF (13.8) / Commanded AF (14.7) = 0.938 then this calculation will be multiplied to the maf at the period point. This way you will have big differences of dailing the maf and thats why i am confused right now. Please clerify it more. Thanks Sent from my HUAWEI matte 20 pro [/QUOTE]
