OLSD tune and Trims section

[willn]

I have a pretty basic question and just curious as I am getting my base tune together.

If I am in OLSD, do I even need to worry about the Trims section of the tune? To me, if the O2s are not used for feedback, this section should not even come into play.

If you are OL then trims do not come into play at all...

however, if your O2S's are physically present, watchout for semi-open loop (SOL) which can enable in OL under the following conditions:
COS: for any cells set to stoich in table B3647.
Non-COS: for any cells set to stoich in table B3605 if B4206 is enabled.

SOL uses STFT to trim.

But, if your O2's are physically removed, then you don't have to worry about the above.
