Narrowband Tuning Tool

I'm an Excel user. The attached screen shots are from my WBO2 Tuning Spreadsheet. The example posted is the average if formula for 1000 RPM _ 50 Kpa filtering out AE / PE / Open Loop then using the Idle Flag for averaging the AFR's of RPM's greater than 900, RPM's less than 1100 and Kpa's greater than 45 and less than 55 Kpa's. The average if formula processes the data on the sheet named "Insert Datalog". Maybe this type of logic will help with your Narrow Band Tuning? There are similar formulas for Count If, along with Standard Deviation forumlas if desired.
