So the VE provides the airmass, and the richer of CFOL and/or PE (if PE enabled) provides commanded AFR.
Then the ECM calculates the fuel required.
We then measure the result with the wide band.

Using FlashScan V1 with NGK-AFX Wide band
Yes voda1. Good description.
wesam, do not command stoich at any time with a custom OS while doing AutoVE. By default, any time you command stoich with a custom OS STFT's are active.(Short Term Fuel Trims) This will skew your data & make the data incorrect.
In the low load areas (up to 75kpa) I use an AFR of 14.5 while doing AutoVE. This is far enough from stoich to prevent the trimming from occuring.
The Tremor at AIR
i tried to put 14.63 as in the AutoVE tutorial and i reached to EQ=1 +-.01 in nearly all cells in 4 runs so should i now go back and command some thing like 14.5 instead of 14.63 to not let the STFT to come active ?

Yes, correct, do two things:
- make sure there are no cells set to stoich in B3647,
- disable B4206.
B3647 is not available in COS1
B4206 already disabled
should i change the 14.63 in the CFOL B3605 to 14.5 ?
