[QUOTE="Denver_SVT, post: 16175595, member: 72321"] Thanks for your usual support Decipha :) [b][U]Here you go the update: [/U][/b]So, as I thought the Crank Relearn test successfully completed and the issue has been fixed. Thanks GOD. No Flashing Check Engine anymore. Now, for proper tuning the Coyotes MAF do you correct the MAF like old models by looking at: 1- STFT B1 and take the Peak value and Valley value (Peak + Valley )/2 to get the average then (1/Average) to get the correction factor at the Period reading which I don't think it will work properly with these models or 2- by multiplying the LTFT Bank1 reading to correct the MAF or 3- Measured AFR B1 / Lambse B1 to get the correction factor and multiply the lbm/min at the period point Note: Those methods above, if we don't have A/F ratio wideband gauge or tuning it at dyno to make the tune much easier. So, Which methods is mush easier and accurate for dialing the maf for Coyotes engines without Wideband gauge or dyno? Thanks, [/QUOTE]
