i.e. I'm saying you have to set those cells to Lambda 0.99 or 1.01 to avoid SOL/STFT.

That is what I am saying... the COS will trim on B3647 cells that are 1.00.
If the COS hits a cell in B3647 that is 1.00, the COS will trim to 1.00 using STFT.
This is a feature of the COS's.
If you set it to command 0.99 lambda, and your wideband measures 0.99 lambda, the BEN will be 1.00 and VE is good.
i.e. you should be adjusting the VE to make BEN converge on 1.00 regardless of what is being commanded.
If you notice, the COS does not have B4206 (enable/disable STFT on 1.00 cells in OL table)...
the OL table cell value being 1.00 enables STFT trimming on it.
Ok, so if I set this to .99 or something else other than 1.0 it will disable trimming?

Interesting and exactly what I want. Trim off idle and cruise, no trims at idle and wot. Fantastic
Now, if I could only figure out why when I first start the car the maf is not failed (CEL is OFF), it runs poorly for a few seconds until CEL kicks on (indicating maf is failed)....the maf wire is removed from the harness

Yes these were set properly along with 101, 102, and 103 to tell me the MAF has been failed (which I turn off to deliver the car).....9 out of 10 times it happens where the CEL would not come on, it would run poorly and then once the CEL comes on it would be perfect. That 1 time, which I cannot attribute to any condition, it is perfect
