I see where you have a table for PE Active AFR however, I don't see anywhere that this is used to create an adjustment for the VE map. Is there a different spreadsheet where this is used?
My other question and please keep in mind this is coming from a Excel/Data geek and not a tuner. Is there a reason you are using the Fixed AFR for Closed loop only rather than using the Desired AFR input which would appear to also work with open loop and PE data and allow you to move into the higher RPM ranges as well. Functionality wise it seems like an easy switch since the desired AFR data is already there. Just insert another table populate it with the Desired AFR and compare that to the WBO2 data. I guess if the issue is related to closed loop data you could use this of the Open Loop and PE data.
Anyway, nice work on the spreadsheet.
