Build 2x 3d table lookup formulas
Put idle air multiplier table into the first

Do a datalog (just use one you've done already) and export to csv.
In the csv locate the timestamp, rpm, ect, min air and dyn air columns. Save those to a new workbook.
In your new workbook slice up the timestamps to 1 every 10 seconds to reduce the row count considerably.
Going back to your table lookup workbook, create a new sheet and insert your log data.
Then write some vb code to iterate over your log data which references the multiplier and min air tables
Plot the output against min air
Make adjustments to the ect table in your spreadsheet and re-run the sim
Review plot and iterate again if needed.
Make adjustment to tune, flash, re-test
OR, look at min air against dyn against rpm over a warm up. Adjust ect table as best you can by your interpretation of the log data. Rinse repeat the next day.
